I’ve had to do this a lot recently, so I thought I’d make a permanent place-holder for the information on how to manipulate the server registry to allow Exchange 2003 to work with an Information Store larger than 14GB. Exchange 2003 SP2 added the ability to configure database size limits.
To modify the size limits for either the mailbox/private store or the public store…
- For a mailbox store, click the following registry subkey:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\MSExchangeIS\Server name\Private-Mailbox Store GUID
- For a public folder store, click the following registry subkey:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\MSExchangeIS\Server name\Public-Public Store GUID
Note These integer values represent the maximum size of the database in gigabytes (GB). For example, a value of 75 represents a database that has a maximum size of 75 GB.
- Click Start, click Run, type cmd, and then click OK.
- At the command prompt, type the following command, and then press ENTER:
net stop msexchangeis
- After the Microsoft Exchange Information Store service has stopped successfully, type the following command, and then press ENTER:
net start msexchangeis
- Click Start, click Run, type eventvwr, and then click OK.
- In the Event Viewer tool, click Application.
- Double-click event ID 1216 to verify that the database size has been set successfully.
