I understand that Microsoft Exchange 2007 has a maximum size limitation of 256GB. My edb database file reached that capacity today. I moved mailboxes out, but the size stays at 256GB. I understand that offline defrag will change that, but since there is now some white space, will the database dismount based on the file size that I see or the actual size of the message store? Am I are still at risk of having the Information Store dismount even after I've moved mailboxes out? We are on MS Exchange 2007 Standard, with SP 3 (Rollup 6) Thank you.

With the introduction of Exchange Server 2007, there are some changes to the Standard Edition so that it now supports up to 5 Databases and up to 5 Storage Groups with Standard Edition. Each of these Databases has a size limit of 16 TB. However, you need to use the Registry Editor to modify a database size limit.

Hi, I was pretty sure they removed the limit on Exchange 2007 Std and Ent edition but you still need to set the registry key (same as Ex2003SP2) to continue to have the store size grow. Check your registry key it's probably been set to 256GB. Start regedit, browse to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MSExchangeIS\<Servername>\Private-GUID and check theDWORD key Database Size Limit in GB". Follow these steps - they are still ok for 2007 - http://www.msexchange.org/tutorials/Explaining-Database-size-limit-changes-Exchange-2003-Service-Pack-2.htmlSean Massey | Consultant, iUNITE Feel free to contact me through My Blog, Twitter or Hire Me.
