|Message:||process name (process id) %3The database name has reached its maximum size of number MB. If the database cannot be restarted, an offline defragmentation may be performed to reduce its size.|
The disk volume that contains an Exchange database has reached the maximum allowed database size.
Exchange Server 2003 Standard Edition has the following limitations regarding mailbox stores and public folder stores:
When you exceed the 16-GB limit on any database, the Microsoft Exchange Information Store service shuts down automatically.
If you have exceeded the 16-GB database limit, you can temporarily increase the database size limit to 17 GB, and then restart the Microsoft Exchange Server Information Store service. Temporarily increasing the maximum size of the information store to 17 GB allows the Exchange database to mount while you reduce the amount of data on the database.
Important To enable this functionality in Exchange Server 2003 Standard Edition, you must create the required new registry value.
For detailed information about how to temporarily increase the database size and resolve this error, see Microsoft Knowledge Base article 828070, “Exchange Server Mailbox Store Does Not Mount When the Mailbox Store Database Reaches the 16-GB Limit” at http://go.microsoft.com/fwlink/?LinkId=3052&kbid=828070.
