Out of the blue I started getting the error message "
V-79-57344-766 - Cannot log on to MAPI with the specified credentials. Review the resource credentia..."
It's a job that's always worked for the past year plus with no issues.
All that is selected in the job is the information store db's, nothing else.
I can see the DB's when I look at the job set up.
When I test the resource creds everything passes.
If I change it to go to disk, it completes in testing but I cannot restore from it and I need it to go to tape like it's been this whole time.
Things I can think of that might somehow play a factor, the service account that I use for backup exec (that has domain admin rights) had it's password recently changed. Everything was backing up without issue for 3 weeks after changing the password but this issue started specifically after failing over our Exchange mailbox server to the failover box, which is something we've done many many times over the past year plus with no issues, but this error started up as soon as we did the fail over this last time, which was the first time since changing the backup exec service account password.
We tried failing back over to the other mailbox server that it was working on but it didn't change the issue/error.
Nothing else beyond doing the Exchange MB failover was done on the Exchange side.
Any ideas?
