Andy, Here's the deal. It depends on what version of Exchange that you are using. On Exchange 2000, Full Exchange Admins is explicitly DENIED and Exchange 2003 is ALLOWED (Microsoft thing). Here's the way I set it up. Create a user account "backupexec". If the media server is a member server, add "backupexec" to the local admins group. Under ESM, make sure that "backupexec" is a "Exchange Full Administrator" under "Delegate control". Under the First Administrative Group / Server / Your server properties, Security tab, make sure that "backupexec" has allowed "Send As" and "Receive As" checked as explicit "Allow" will overide the inherited "Deny". You will also need to do this at the "Mailbox Store" object in ESM as well. Then, logout of your media server and login as "backupexec" user and create or modify your jobs. Let me know how you make out.
