Hello,
Could you please state the :
1. The exact error message as seen in the job log.
2. What changes were made to the account or elsewhere that provoked these failures.
3. is the exchange Db locally installed or remote.
4. Check the system event log for any error related to the store.exe closure.
5. Check if you have any alerts in backup exec.
Apart from this also ensure that you backup only the mailboxes in a seperate backup to isolate the issue.
