Temporarily increase the Exchange database size limit by 1 GB

Exchange 2000 and Exchange 2003 Standard Editions limit the information store size to 16gb.
It is the total database size, including the EDB and the STM file, not just the EDB file.

When the mailbox store database in Microsoft Exchange Server 2003 Standard Edition or Microsoft Exchange 2000 Server Standard Edition reaches the 16gb size limit, the mailbox store does not mount.

To resolve this issue, new functionality has been added to Exchange 2000 Standard Edition that allows an administrator to: Increase the 16GB limit by 1GB to allow for recovery.

In Exchange 2003, this functionality is built into the product. However, to enable this functionality, the administrator must create the new registry value:

Location: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MSExchangeIS\Private
Value: Temporary DB Size Limit Extension
Type: REG_DWORD
Value Data: 1

To resolve this issue in Exchange 2000, you can apply the September 2003 Exchange 2000 Server Post-Service Pack 3 Rollup. This update requires that you install Exchange 2000 Service Pack (SP3) and install the 813051 update on your server.
824282 September 2003 Exchange 2000 Server Post-Service Pack 3 Rollup
