|Message:||Exchange store ‘<storage group name>‘: The logical size of this database (the logical size equals the physical size of the .edb file and the .stm file minus the logical free space in each) is <number> GB. This database size has exceeded the size limit of <number> GB.If the logical size of this database is not reduced to less than the maximum size limit, this database will be dismounted the next time a database size check is performed.|
This event is logged if the first size check after a database is mounted identifies the logical size of the database to be greater than the limit that you have configured. The text in the event description identifies the database that has exceeded this limit and the current logical size of the database. The logical size of a database equals the physical size of the .edb file and the .stm file minus the logical free space in each. By default, Exchange Server checks the size of each Exchange database at 5 hours after midnight (5:00 AM). The database specified in the event text has been dismounted.
Because this event indicates that you have reached the maximum database size, you should take immediate administrator action to avoid any disruption of e-mail service for your users. The database that has exceeded the database size limit will be dismounted the next time the size check determines that the size limit has been exceeded.
If you are running Exchange Server 2003 Service Pack 2 or later, you can configure the maximum database size, the threshold at which a warning event is logged, and the time of day at which database sizes are evaluated. For information about how to configure these settings, see “Configure Database Size Limits” in Exchange Server 2003 SP2 Online Help.
To reduce the size of the database:
Note If you have not configured the size limit for an Exchange database to the maximum allowed size, you may want to increase the size limit for the database specified in the event description. See the Explanation section of this article for the maximum configurable size limits depending on the version of Exchange Server that you are running. However, backup and restore operations will take longer if you increase the size of the database.
