Renuka,
I have walked thru each and every item in the 266177 document you mentioned below as well as all "related" articles to no avail.
The BackupExec user logon and its password are confirmed as setup and consistent across the board on the local exch srvr as well as in ADUC.
When I am in BackupExec and Job Setup Full Properties | Source-Selections window ... when I select any such as C, D, E, etc. on any of the servers/drives it shows me the subselections. However, when I click on the Mailbox or Public Folders items ... it immediately pops up the Logon Account Selection window with a message at the top showing
Logon Account "NEWHOPE\Backup Service Account" failed to access "\\NHEX01\Microsoft Exchange Mailboxes". Access is denied.
Same error with Public Folders.
This is essentially the same issue as reported in the log files mentioned in the initial post .. which are re-occurring each day.
However, the BackupExec logon account is confirmed setup exactly the same way on each server, etc.
The only thing I noticed is that the logon account was located in a unusual place in ADUC so I moved it to my Managed Objects OU ... but that should not make a difference.
Any other suggestions are very appreciated.
Brian
