Failing to backup Exchange 5.5 mailboxes

Failing to backup Exchange 5.5 mailboxes

Failing to backup Exchange 5.5 mailboxes

WinNT 4 sp6 Backup Exec 8, Exchange 5.5 sp3.

Error message has started occurring stating that the mailboxes are not being backed up, "Access denied".

I have read the Technote (Veritas Knowledgebase) article on the Edbbcli.dll, and re-named the existing dll and re ran Exchange sp 3 install to reinstall the dll to no avail. The user that Backup Exec is configured with has Admin rights within Exchange.

When I try to select Mailboxes in Backup Selections the dialog box pops up requesting which mailbox it should use, when I input the correct mailbox name for Backup Exec it "Cannot attach". The Exchange Information Store and database are being backed up (at least no error messages).

The only thing that I can think of that may have triggered this is the removal of some users from NT/Exchange on this server.

RE: Failing to backup Exchange 5.5 mailboxes

I had the same problem last week, after doing some housekeeping on Exchange Server.

The Information Store, and Directory backed up okay, but the mailboxes failed, saying 'Access Denied'.

Having deleted some obsolete mailboxes, I had also taken the opportunity to make the Backup Exec mailbox 'hidden'.( to hide it from the address book of other users )

Unfortunately, it seems that BackUp Exec could not see it either! After clearing the 'hidden' flag, the backup ran fine.

I hope this helps.

Yep that seemed to do the trick - Thank you. I suppose this is another 'feature' of NT!

RE: Failing to backup Exchange 5.5 mailboxes

I'm glad it worked!
