I'm running Exchange Server 2003 and Backup Exec 10d on the same server. I try and select the Microsoft Exchange Mailboxes to backup but I get the "logon account failed to access the mailbox" error.
I have reviewed several technotes and have done the following.
The service account that I use is unique and has a unique mailbox name
The service account is NOT hidded from the Global Address List
The service account has Full Exchange Administrator rights to the Exchange Organization
The service account is a local machine admin (and has domain admin privs as well)
The point at which I run into trouble comes from KB article #249456 ( http://seer.entsupport.symantec.com/docs/249456.htm ), specifically instructions #18 and #27
at #18, it say I need to grant the service account Send As and Receive As permissions, however, the account (in fact all the accounts) have inherited explicit Deny on those permissions (which can't be turned off without turning off inheritance), and if I recall from my A/D training, if you have both allow and deny rights to something, the deny always wins.
at #27, it says I need to Select Allow for everything except Associated external account, but like above, everything is inherited and i can't select any of those items.
What can I do to fix this?
