Microsoft doubles Exchange Online, Office 365 mailbox size

Toni Boger Toni Boger Profile: Toni Boger

In a blog post this week, Microsoft said user mailboxes in Office 365 and Exchange Online are doubling in size.

The company said the current capacity at 25 GB will go up to 50 GB. There is no price increase with this change.

The size increases begin rolling out to current customers this week and will continue through November.

Customers with Office 365 Small Business, Midsize Business, Enterprise E1, Exchange Online Plan 1, Government G1 and Education A1 service plans will be affected by the change.

The company said resource mailbox and shared mailbox sizes will also increase to 10 GB, more than doubling the current storage size.

Microsoft rereleases Exchange security update

Toni Boger Toni Boger Profile: Toni Boger

Microsoft rereleased a critical Exchange security update nearly two weeks after pulling it, assuring customers that it was tested before it was released.

The original issue with the security update, MS13-061, came from the Search Host Controller service. End users came across the problem when checking email with Office Web App (OWA) on Exchange 2013.

After update was pulled, IT pros questioned Microsoft’s plans to have quarterly updates for Exchange and suggested the plans were in jeopardy. One IT pro called the pull “the latest in a long line of cock-ups.”

Microsoft said the update was tested in its own Exchange dogfood environment before releasing it. The company also made sure search settings would be reinstated after installation.

The link to the Exchange Server 2013 CU1 update can be found here, and the link for Exchange Server 2013 CU2 can be found here.

Profiling the best Exchange Server professionals (June 2013) – Dave Stork

Matt Gervais Matt Gervais Profile: Matt Gervais

I hope everyone is having a good summer so far. This month, I’m again pleased to announce the most recent recipient of our monthly “Profiling the best Exchange Server professionals” program – Dave Stork.

You may recall from past posts that there have been a few recipients with multiple nominations. Well, Dave is another key member of the Exchange community who was nominated multiple times by his peers, Dave is another person with a solid blog, is always tweeting helpful information and offering helpful advice, and also partakes in the terrific UC Architects podcast series.

I can personally state that Dave is always extremely receptive and helpful with any questions I have, so when I saw that he had been nominated several times, it was an easy choice. I caught up with Dave this week to ask him a few questions regarding 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?

I had already had a little experience with administrating Exchange 5.5 and 2000, but my employer offered internal training for MCSA 2003 with Exchange 2003 as an elective exam. It took me three tries to pass the exam, but afterward I admitted to my manager that I actually liked Exchange. After that, I got mostly Exchange-related projects, since I had the most experience… me and my big mouth.

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

There are a lot of things I enjoy, but I mostly concentrate on transitions and migrations. A successful migration should have little to no unexpected negative effects on end users; that’s something I really enjoy seeing through. That said, I also quite enjoy training and coaching customers and co-workers in both old and new versions of Exchange. This is especially true when it comes to explaining new features that will ease folks’ burdens and result in higher productivity.

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

I’m very excited to continue working with Exchange, as it’s still my main focus and specialty. I also hope to see more and more Exchange 2013 deployments, especially those that would benefit from enhancements in 2013 compared to 2010.

We’ll probably see some interesting updates for Exchange 2013 this year. They’ve already lifted the veil on some of the new features coming in CU2, but I think we can expect interesting things in CU3 and perhaps CU4 as well this year. I also keep my eye on Office 365, Azure and Lync projects. I definitely see interest growing in those products and I think they can complement a lot of Exchange environments.

Do you have someone you think should be nominated for our monthly award? Write us and let us know.

Until next time,

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,

A spring pitch for our Ask the Expert section

Matt Gervais Matt Gervais Profile: Matt Gervais

Back in January, I urged readers to be part of our Ask the Experts revival. I’m here now not only to reiterate that suggestion, but also to highlight some of the terrific expert responses we’ve published since then.

For example, now that customers are free to migrate to Exchange 2013, we’ve covered numerous helpful topics that folks are sure to run into during their migrations, such as:

These aren’t the only questions we’ve answered since January, so do yourself a favor and head over to the expert answer section of our site and peruse commonly asked Exchange questions, both old and new.

Also, we’re always looking for new talent to answer reader-submitted questions and write expert tips. If you’re interested in the opportunity, feel free to email me at your leisure.

If you have questions of your own, feel free to either write me personally, or drop them in our editor mailbox. Either way, I’ll see them and pass them on to one of our experts.

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,
