I am getting a lot of errors during the backup of CERTAIN MS Exchange Mailboxes and this only started happening about a month ago; before which everything worked very well.

There have been no software or hardware changes.

Here are some of the relevant portions of a Job Log:

Job ended: 04 January 2007 at 02:42:37
Completed status: Failed
Final error: 0xa0008488 ? Access is denied.

Final error category: Security Errors

--------------------

Because these errors are only being produced on particular Mailboxes it cannot be that the BackupExec Logon Account doesn't have the required permissions to access these files. I also know that the relevant users have not got Outlook open during the time of backup so the particular files being skipped will not be 'in use'.

I will make the observation that ALL the errors are related to items in the 'Calendar' folder.

It makes Job Logs very uneasy reading when you see so many errors! :(

Does anyone have any ideas or fixes please?
