Transaction logs were not purged because at least one database is offline.

Explanation

This Error event indicates that an error occurred when Exchange Server tried to delete the transaction log files associated with an online backup set. The reason that the transaction log files could not be deleted is because one or more Exchange database files were not online when the online backup operation started. All Exchange databases must be online for an online backup process to be completed successfully.

User Action

To resolve this error, use the information provided in the event to identify the database that was offline at the time that the online backup operation started. Use the Exchange Management Console to determine whether the database identified in the message is currently online. If the specified database is not online, bring it online. If the specified database is currently online, the database may have been temporarily offline when the online backup process started.
