Configure circular logging for a mailbox database

When you enable circular logging for a mailbox database, the type of circular logging you get depends on whether or not the mailbox database is replicated using continuous replication:

  • If the mailbox database is not replicated, it will use JET circular logging. In this case, enabling or disabling JET circular logging will require a dismount and mount of the database.

  • If the mailbox database is replicated, it will use continuous replication circular logging (CRCL). In this case, enabling or disabling CRCL takes effect dynamically; there is no need to dismount and re-mount the database.

For more information about circular logging and CRCL, see Exchange Native Data Protection.

  • Estimated time to complete: 1 minute

  • You need to be assigned permissions before you can perform this procedure or procedures. To see what permissions you need, see the "Mailbox Database Permissions" entry in the Recipients Permissions topic.

  1. In the EAC, go to Servers > databases.

  2. Select the mailbox database you want to configure and click Edit icon.

  3. Check or uncheck the Enable circular logging checkbox, and then click save.

  4. If a dismount and mount operation are required, a warning message will appear. Click OK to close the warning message.

    1. To dismount the database, click More More Options Icon, and then click Dismount. Click yes when the warning message appears.

    2. To mount the database, click More More Options Icon, and then click Mount. Click yes when the warning message appears.

Set-MailboxDatabase DB1 -CircularLoggingEnabled $True

This example disables circular logging for database DB1.
