When using DiRT to backup Unity, we are facing three issues:
1) error backing up UnityDB
2) error backing up ReportDB
3) unable to backup mailboxes because Administrator account has no "Send As" and "Receive As" privileges on the Exchange.
For issues 1) and 2) we tried to add more privileges to the Microsoft SQL Enterprise Manager Administrator account, but the result was the same. We even tried creating a new account (with all privileges) and performing the DiRT backup with that account, but got the same errors.
As for the 3rd issue, the Microsoft Exchange System Manager application has no way to provide "Send As" and "Receive As" privileges to accounts. Where can those privileges be assigned?
