Which version of Exchange 20043 will all partition of the Information Store

Microsoft Exchange 2003
In the article - Partition the Information Store,By Mike Daugherty - 14 Jun 2004 | SearchExchange.com, he stated that the Information Store could be partitioned into 20 databases. He did not say whether the Standard version of 2003 or the Enterprise version of 2003 was required. Do you know if the Standard version can be partitioned? And if so, can you get 16 gig per each of the 20 databases or does the 16 apply to the total of the 20 databases? If this will not work on the standard version, do you know of a method to work around the 16 gig limit? I did not see the limit back when I purchased the license and have not installed and upgraded to 2003 yet so I am trying to find a way the school system can use what we have.

Thanks. We'll let you know when a new response is added.

My understanding is that the standard version of Exchange 2003 is bound by the same limitations as version 5.5–a single storage group with a limit of 16 GB. For multiple storage groups or to have a store larger than 16 GB, you must use the Enterprise Edition of Exchange 2003. There are articles out there on how to upgrade from the Standard version to the Enterprise version of Exchange. Microsoft’s official article can be found at http://support.microsoft.com/?id=170280.

    The Standard Version of Exchange is limited to 16 GB per Store, and you are only allowed one Mailbox Store. However, you also have a Public Folder Store that also has a 16 GB limit on it. So one way to work around the limitation problem is to create a User Folder in the Public Folder Store with the same rights as the Users mailbox. This way the user can copy any information from their mailbox to their Public Folder. This essentially doubles your storage capacity (if you don't use PF to a large extent) and all information is backed up and accessable remotely. Another option is to purchase an Email Archiver that moves messages to a near offline storage device (Share, NAS, SAN) and is extracted as needed. These products often combine with Outlook and OWA so it appears all information is sitting in the users mailbox. This also allows you to keep all information server side without pushing your Standard Exchange limitations. Hope this helps!

    You can increase the 16Gb limit to 17Gb with a registry change... Requires Service Pack 3 for Exchange 2000 and the following registry entry: Click Start, click Run, and then type regedit.exe. Locate the following key in the registry: HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesMSExchangeISPrivate- On the Edit menu, click Add Value, and then type the following in the Value name box: Temporary DB Size Limit Extension Select REG_DWORD for the data type, and then click OK. Enter a value of 1, and then click OK. Quit Registry Editor.
