Changing the store limits in Exchange 2003 Standard SP2 March 9, 2009

Just a few months ago, i encountered several errors messages in event viewer regarding MS Exchange Information Store,  I found that my clients exchange database had grown to 17GB, to fix this issue i installed Service Pack2 for exchange which allows the store limt to grow but does not change from default (16GB), below is the method to increase to store limt from 16GB to 75GB (maximum).

1. On the computer running Exchange Server, start Regedit.exe.

To configure the database size limit on a mailbox store, use the following registry key:

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\MSExchangeIS\Server name\Private-Mailbox Store GUID

Create a new DWORD entry called “Database Size Limit in Gb” and give it the appropriate value for maximum database size in GB. For Exchange Server 2003 Standard Edition type a value between 1 and 75 (the value represents in GB). For Exchange Server 2003 Enterprise Edition type a value between 1 and 8000 (the default is 8000 GB). Click OK.

Note: Entries should be in decimal format.

Create a new DWORD entry called “Database Size Buffer in Percentage” and give it the appropriate value between 1 and 100 to specify when you want events to be logged in the application log in Event Viewer to warn you that you are nearing the maximum size for a database.

The default value of 10 (i.e. 10%) will result in warning events to be logged when you have 10 percent capacity left before you reach the maximum size for that database.

Create a new DWORD entry called “Database Size Check Start Time in Hours From Midnight” and give it the appropriate value between 0 and 23 to specify when you want Exchange to check the database size. The default value of 5 results in Exchange Server checking the database size 5 hours after midnight (i.e. 5:00 AM).

Close Registry Editor.

For this patch to work you must dismount your information store and remount, a reboot seems to work best.
