Make sure you have sperate backup created which is backing up just the Exchange information Store and the AOFO option is not selected in the backup job properties ...
If you have the Aofo option selected uncheck it and retry the backup job again ...

Removing the AOFO option would prevent the server getting lock and also will allow the users to send and recive email even when the backup is running . Howerver GRT based full backups of Exchange databases may run at an acceptable rate, however, incremental backups may run comparatively slow (i.e. there is a considerable difference in the backup speed of full and incremental backups).
 Solution:
 1. Make sure Backup Exec is fully patched and the Backup Exec Remote Agent on the Exchange server (if it is remote) is updated afterward.
2. Run an offline defragmentation of the Exchange database.  Refer to the Microsoft KB Article below for additional information on how to run a defragmentation on the Exchange database.

Please check/try the following:

1) in the exchange server check the vss writers:from the CMD type vssadmin list writers and check if the Exchange writer is "ready" or ina "retriable" state..in the last case do a reboot of Your exchange server.

2) did you manually deleted the log files on exchange or the full backup missed to delete some log files, if so, clean the log files with the exception of today and the day before than run a full backup.

3) delete all the exchange job backup and recreate them completly before test the job again.

let me know if it works.
