“

An attempt to prepare the database 'Mailbox Database <ID>' for backup failed because the database is already in the process of being backed up. The error code is -2403. (Note that if a backup was recently aborted, then it may take several minutes for the system to detect the aborted backup and initiate backup cleanup procedures, so this message may be generated if an attempt was made to backup a database before a previous backup attempt had fully terminated.)

“

Steps

1.       Dismount and remount the database.

2.       Restart Microsoft Exchange Information store service

Please note: The above action will disconnect your outlook client
