| Description | Information Store (3160) The database D:\Program Files\Exchsrvr\MDBDATA\priv1.edb has reached its maximum size of 16383 MB. If the database cannot be restarted, an offline defragmentation may be performed to reduce its size. |
| Event Information | According to Microsoft: CAUSE: This issue may occur if the Exchange mailbox store database has reached the 16-GB size limit. The Messaging Database (MDB) shuts down automatically and will not restart as soon as the mailbox store database has reached the maximum size limit. This behavior is by design to keep the system from trying to insert more data into the mailbox store database than the mailbox store database was designed to handle. RESOLUTION: To resolve this issue, new functionality has been added to Exchange 2000 Standard Edition that allows an administrator to: 1. Temporarily increase the database size limit by 1 GB. 2. Selectively remove unnecessary database content. 3. Defragment the database to reduce the database to a level that is in the defined boundaries of the database size. |
