Experts weigh in on Exchange 2013 Server Role Requirements Calculator

Matt Gervais Matt Gervais Profile: Matt Gervais

If you’ve been following the Exchange team’s blog with any sort of regularity recently, I’m sure you’ve probably seen that they’ve been dropping a lot of updates and new tools.

Just to name a few, there’s the:

  • Updated Exchange 2013 Deployment Assistant,
  • The new Message Analyzer tool,
  • The Exchange 2013 Management Pack, and
  • The Exchange 2013 Server Role Requirements Calculator.

The last item in this list is one that’s really seemed to get a lot of press, so I asked a couple of my most trusted Exchange experts — Dave Stork and Michael Van Horenbeeck — on their thoughts regarding the calculator.


To start, Stork pointed to the importance of the expansion of the calculator since the 2010 version, which only accounted for the mailbox server role.

“Remember, Exchange 2013 has a different infrastructure. Where in Exchange 2010, the UM role was separate, it’s now part of the 2013 mailbox role,” said Stork. “Those changes in infrastructure explain the difference in results of both calculators.”

Both experts also noted the dramatic memory increase from an eight GB minimum in the previous iteration (multi-role), to the now 24 GB minimum in the Exchange 2013 version:

“I think a lot of people will be surprised when crunching numbers. I admit, I was too at first,” said Stork.

“[When I saw the] numbers change so drastically, there was a bit of a shock. It’s not that it’s a problem though, memory is relatively cheap and CPU is usually under-utilized,” added Van Horenbeeck.

The important point to understand here is that these new memory requirements will more-than-likely affect Exchange 2013 deployments.

“For smaller shops, having to split up 24 GB for a deployment of limited size might prove too much,” said Van Horenbeeck. “The same applies for virtualizing Exchange 2013; even though it’s fully supported, who wants to virtualize a memory-crunching machine like that?”

“These requirements could mean that the adoption of [Exchange] 2013 will be slower for smaller companies; the Netherlands has a lot of companies in the 100-500 range, vastly smaller than the U.S.,” added Stork. [It’s also possible] that the adoption of Office 365 or other hosting providers will gain traction.

Upon reading this post, another trusted Exchange expert, Michel de Rooij wanted to share his thoughts as well.

“People should also be aware that the calculator tries to make recommendations based on available DIMM sizes, for example eight, 16, 24, 32,” said de Rooij. “That makes less sense of course when virtualizing Exchange. Also, for small memory amounts you get a ‘penalty’ as the minimum amount for the Content Indexing (new engine) already starts at 10 GB.”

What are your thoughts on the new calculator? Let me know.

Until next time,

Profiling the best Exchange Server professionals (May 2013) – Oliver Moazzezi

Matt Gervais Matt Gervais Profile: Matt Gervais

I’m quite pleased to announce the latest recipient of our monthly “Profiling the best Exchange Server professionals” program – Oliver Moazzezi.

Another individual who was nominated multiple times by his peers, Oliver runs a terrific blog, is a prolific tweeter and has been awarded the title of Microsoft Exchange MVP.

I recently spoke with Oliver about a hosted Exchange feature I was working on, (which you’ll find in our June Modern Infrastructure e-zine) but I was also fortunate enough to catch up with him this week to ask him a few questions about how and where he got started with Exchange, as well as his plans for the future.

1. Can you give a brief description of how you began working with Exchange Server and related technologies?

This is a funny one. I studied animation and computer visualization at university, gaining a BA (Hons), but simply could not get a job after graduation. In 2001, I took a part-time job at Cobweb Solutions, as I was adept at computers. That part-time job turned into a full-time one, and I worked my way up to the second line support team, and later became a systems admin.

From there, I really got into Exchange and Active Directory, having a large part in Cobwebs’ Exchange 2000 and Exchange 2003 hosting platforms. I then became the Exchange team lead, and I later designed — as one of two principle architects at Cobweb — the Exchange 2007, 2010 and 2013 hosting platforms. As you can see, it has been one hell of a ride through all the various support roles to where I sit now, overseeing our Exchange and Lync hosting platforms.

2. What’s your favorite part of working with Exchange Server and related technologies?

For me, I think it has always been the scale of the platform. I was just always really into Exchange once I got my hands on it. It’s something I picked up more naturally than any other Microsoft server technology. My primary focuses are Exchange, Lync and Active Directory, and they excite me just as much as when I first started working with Exchange 10 years ago.

3. What are you excited to work on in 2013 and why?

I have to say the cloud. The last 24 months have really been the era of the cloud, and I’m excited to finally see companies take it seriously. It was a hard sell 10 years ago, but through perseverance and the Google/Microsoft fight, it has really gotten into the mainstream. For that, I am proud of what myself and the teams at Cobweb have achieved.

Please join me in congratulating Oliver by tweeting this post.

Until next time,

Profiling the best Exchange Server professionals (April 2013) – Jeff Guillet

Matt Gervais Matt Gervais Profile: Matt Gervais

Since beginning the “Profiling the best Exchange Server professionals” program last October, I’ve relied on those in the Exchange community to nominate worthy candidates for the award. This month, I decided to flex a little editorial muscle and go outside that process. As the April 2013 recipient, I’ve personally selected Exchange MCM and MVP Jeff Guillet.

I somehow became aware of Jeff’s contributions only during last September’s Microsoft Exchange Conference, but I’ve been following his helpful and insightful tweets and blog posts ever since.

Over the past few months, Jeff has written some really noteworthy blog posts, and I’m sure if you’ve read them or follow him on Twitter, you’ll agree that he’s incredibly deserving of the award. As I do with all award recipients, I asked Jeff to share how he got started with Exchange, what he’s excited to work on this year and more.

 *Please join me in congratulating Jeff by tweeting this post.

1. How did you begin working with Exchange Server and related technologies?

I began my career as a BASIC programmer in 1984. This background helped me hone my skills troubleshooting and debugging. In 1996, I took a position for a company in the San Francisco Bay area managing its IT infrastructure, including upgrading the email system to Microsoft Mail 3.02. It was here that I earned my MCSE certification for Windows NT. 

I then made the jump to a consulting company and began specializing in Exchange in version 5.5. I’ve been awarded Microsoft MVP status every year since 2009 and have upgraded my Microsoft certifications for each version of Exchange and Windows. I also earned my Microsoft Certified Master for Exchange in 2011.

2. What’s your favorite part of working with Exchange Server and related technologies?

I enjoy working with Exchange Server because it’s so important to every business. I also enjoy working with customer email systems to solve business needs and security requirements. I take a lot of pride designing and implementing highly available and fault tolerant solutions for customers.

3. What are you excited to work on this year and why?

There are several projects this year that I’ve enjoyed working on, including bringing customers up to the latest version and features. I’m excited to be working with Exchange 2013 and to offer design solutions that provide automatic site fault tolerance through global server load balancing.

Until next time,

Profiling the best Exchange Server professionals (March 2013) – Paul Cunningham

Matt Gervais Matt Gervais Profile: Matt Gervais

Since launching our “Profiling the best Exchange Server professionals” program, we’ve had numerous deserving nominees and winners. This month, I’m happy to present the award to the most oft-nominated individual, and with good reason, Paul Cunningham.

If you’re not familiar with Paul or his terrific site, allow me to put it very simply. Paul writes about anything and everything Exchange Server-related. He’s has a multitude of terrific in-depth articles on Exchange migrations, PowerShell code, backup and recovery, ActiveSync, DAGs and, well you get the point.

Don’t take my word for it though, visit his site and follow him on Twitter if you don’t already.

Paul was nice enough to answer some questions on his background, including how he started working with Exchange, favorite aspects and much more — which you can read below.

Please join me in congratulating Paul by tweeting this post.

1. How did you begin working with Exchange Server and related technologies?

Back in 1999, I got my first job in IT working on the help desk in a government department that ran Exchange 5.5. I still remember the tiny mailbox quotas and heavy .pst file use. I’d never even had my own email address before then.

Over the next few years, I worked in a bunch of different operations and projects roles, but Exchange Server was always a part of that. I had moved into a consulting role right around the same time Exchange 2007 shipped, and one day my boss asked me if I wanted to take over for the messaging lead who was leaving to go live overseas. That was the beginning of my focus on Exchange Server in my career, and it’s been that way ever since.

2. What’s your favorite part of working with Exchange Server and related technologies?

Exchange Server integrates and interacts with so many different things. I like to think about all the people in all areas of a business, as well as the various aspects of IT infrastructure like storage, virtualization, load balancers, firewalls, WAN, mobile and more.

The complexity can be challenging, but also a lot of fun. I really do enjoy dealing with the constant stream of new things that crop up. You can work with the product for years and still be learning new things, or coming across new scenarios that expose you to different facets of the product.

3. What are you excited to work on this year and why?

I’m looking forward to Exchange 2013 CU1 shipping so that we can accomplish coexistence with Exchange 2007 and Exchange 2010. Getting involved in some migration projects here should be very interesting.

I didn’t get the chance to dive into Lync or Office 365 much last year, so I also want to spend more time on those products.

Finally, I’m also co-authoring a new ebook on Exchange 2013 and PowerShell at the moment. We’re hoping to finish that in the next couple of months.

Do you have someone you’d like to nominate? Email me.

IT pros OK with Exchange 2013 CU1 delay

Matt Gervais Matt Gervais Profile: Matt Gervais

IT pros are going to have to wait a little longer — two days actually — before they can begin migrating to Exchange 2013. And many are fine with waiting, as long as all the kinks are actually ironed out.

In a proactive announcement earlier this week, the Exchange team announced that the cumulative update for Exchange 2013, previously promised by the end of Q1, would be pushed back two days.

In February, the Exchange team announced a new way to service Exchange Server. It would roll out cumulative updates (CUs) at the end of each quarter. The updates replace past rollup updates, and the schedule was intended to give IT shops a better idea of when updates would become available. The hope was that the predictability would not only help Exchange shops, but the Exchange team and testers as well. It would give them a set amount of time to fix the bugs present in the product.

The first Exchange 2013 CU was to allow for coexistence with Exchange 2010 and Exchange 2007, helping Exchange shops begin the migration process to Exchange 2013. Now they’ll have to wait just a little bit longer.

“Of course I’m a little disappointed, but I fully support Microsoft’s decision not to release the CU just yet,” said Michael VanHorenbeeck a technology consultant at Systems Integrator Xylos Corp. in Belgium. “It proves to me that Microsoft is making an effort to improve the quality of the product — and its updates — a welcome change after the debacles with previous updates.”

Another member of the Exchange community shared a similar sentiment. “It’s basically just two days late, not really a big deal, and I prefer quality more than just having those bits, said Dave Stork, an IT architect based in the Netherlands. “I would have been more upset when it was delayed for a month or so.”

Another IT pro explained why the release would be delayed. “Waiting a few more days is a small price to pay when we’ll get an update that doesn’t require people on Exchange 2010 SP3 to install yet another update on Exchange 2010 CAS servers, said Michel de Rooij, a unified communications consultant in the Netherlands.

“Looking at the time required by some companies to test, accept and put updates in production, introducing another update for the current production platform would be unwelcome. I applaud this decision,” he added.

Look for Exchange 2013 CU1 on April 2.

Until next time,

Tool, info updates released as admins prep for Exchange 2013 migrations

Matt Gervais Matt Gervais Profile: Matt Gervais

About six months ago at MEC 2012, we heard that Exchange 2010 SP3 would be released in early Q1 to support Exchange 2013 coexistence. Well, Microsoft kept true to its word, and Exchange 2010 SP3 was released in February. It came with a caveat, however: Exchange admins would need the first cumulative update (CU1) before they could migrate to or coexist with Exchange 2013.

The Exchange team has held strong to its statement about CU1 being available “in Q1 2013.” Now as we get closer to the end of the first quarter, we’ve seen several announcements regarding tools and information that will be important as organizations look to move to Exchange 2013 and Office 365.

* First, there was a blog update on the TechNet URLs for Exchange 2013. This caused a stir when it was first announced, and folks still aren’t happy about the URL changes. However, the fact remains that the info contained within these pages will be critical as companies plan for and migrate to Exchange 2013.

* About a week ago, we saw an update on Exchange Server 2013 Deployment Assistant (ExDeploy). If you’re not familiar with previous versions, ExDeploy is a Web-based tool that helps administrators plan Exchange upgrades and installs. The tool asks several migration-related questions, then spits back a checklist on what you’ll need to do to properly deploy or configure Exchange.

The Exchange 2013 version helps admins plan not only for on-premises deployments of Exchange 2013, but also hybrid and Office 365 environments.

* Last week Microsoft also released the Exchange 2013 version of the Jetstress tool. This will be extremely important to organizations that want to be among the first to run Exchange 2013 in production. Simply put, the Jetstress tool tests disk stability and performance before placing an Exchange 2013 server into production. This is a highly recommended download.

* Today we saw an update to the Remote Connectivity Analyzer (RCA). This tool lets admins check Exchange, Lync and Office 365 connectivity problems. The updated version of the RCA includes several new Office 365 tests that are sure to be put to good use this year.

I, for one, am glad to see all this updated information prior to the CU release. Like others, I was surprised that the SP3 release didn’t officially allow for coexistence with Exchange 2013. But now that I’ve seen this information trickle out before the CU1 release, it certainly seems like a good sign of things to come.

Profiling the best Exchange Server professionals (February 2013) – Michel de Rooij

Matt Gervais Matt Gervais Profile: Matt Gervais

I’m very pleased to announce the recipient of our February 2013 “Profiling the best Exchange Server professionals” award – Michel de Rooij!

If you follow anything and everything Exchange Server-related on Twitter like I do, you’re sure to have seen any one of Michel’s countless contributions to the community.

  • Michel participates in the terrific UC architects podcasts (make sure to catch these – seriously).
  • He frequently blogs on Exchange and related matters.
  • As mentioned, he’s all over Twitter with helpful tweets.
  • He contributes helpful scripts.

This week, I was able to email with Michel in order to congratulate him on his award and ask him a few questions:

How did you begin working with Exchange Server and related technologies?

I’m actually a late bloomer when compared to the other great Exchange folks out there. I was involved in the migration/deployment scripting business for some time, but in 2004, I got the opportunity to join a global team responsible for defining and developing the email and collaboration (Exchange-based) standard at a large international banking and insurance company. This project required thoughtful planning. It also required me to dive deep into the product in order to understand it backwards and forwards.

Part of the job was also developing and maintaining a fully automated deployment tool (a set of scripts and HTML application as GUI) that allowed implementers to deploy Exchange using predefined building blocks. Long story short, it was a great learning experience and I decided to stay with Exchange and development.

 What’s your favorite part of working with Exchange Server and related technologies?

My background in software development has proved invaluable as PowerShell and scripting knowledge is becoming more important every day. Scripts are not only important in completing tasks, but also in accomplishing them faster and more efficiently.

While I like working with Exchange or related technologies like Active Directory, at the end of the day I get the most joy from helping others. This might mean helping them perform a task or solve a problem. This allows them to do a better job, do it faster and do it consistently. Depending on the complexity of the issue, I usually begin by setting out workflows or pseudo-code on a piece of paper and translating it to a PowerShell script.

If [the scripts] are considered potentially useful to the Exchange community, I work to make them general-purpose and fool proof before publishing. Note that developing a robust script shouldn’t be underestimated; it requires lots of testing and additional code.

What are you excited to work on this year and why?

I’m looking forward to all the challenges that are sure to arise after the Exchange 2013 Cumulative Update 1 release. Besides that, I’m working on some exciting side projects, like PowerShell-related workshops. I also plan on continuing to contribute to the Exchange communities and projects like the UC Architects podcasts. I also hope to to finally meet some overseas peers in person this year as well.

Please join me in congratulating Michel by tweeting this post. And don’t forget to mail your nominations for our March (and onwards) winners.

Until next time,

Well, I’m finally an user

Matt Gervais Matt Gervais Profile: Matt Gervais

Back in July, I blogged that the release freaked me out. Fast forward about six months and I’m finally an user. The truth is, I don’t hate it as much as I thought I would.

This morning I was explaining the impending wholesale change from to to a colleague and wanted to show him the difference. I logged into my account as I do every day to show him the interface. I then logged out and logged into with my Hotmail address to show him the interface. I didn’t realize I’d be waving goodbye to my Hotmail interface forever.

We both noted the semi-cleaner interface and change to a blue task bar. I’d seen this all before. When I went to switch back to the interface (sorry, I’m a creature of habit), I noticed that the option was no longer there:

From there, I Googled – sorry, I mean Binged — “how to switch interface back to” and quickly found out that it was no longer an option.

While I don’t like the fact that I was no longer given the option to use Hotmail, nor a heads up as a user, I understand that it’s part of Microsoft’s plan to get all their services under uniform product names.

Faced with my new life as an user, I decided to send some messages to test it out. I must admit, though it’s much different, I really like the new mail sending interface.

As you can see above, it takes up the majority of the screen. You can enter recipients’ email addresses in the To: field on the left-hand side of the page and autofill is still an available and much appreciated option here.

I’m sure it will take some time to get used to this new way of doing things, but I’m looking forward to it, as I’m looking forward to the Office 365 rollout next week. It’s certainly an exciting time to be a Microsoft customer.

And I always have my Gmail account to turn to if things don’t work out.

What do you think about the upcoming Office 365 rollout or the change? Write and let me know.

Until next time,
