Hello all,
I have a user with several mailboxes he has Full Access and Send-As permission to. He is intermittently getting NDRs when he tries to send messages from one of them.
I can't find any pattern to the errors. Maybe 1 in 10 bounce.
We have Exchange 2010 and Outlook 2010.
The mailboxes were added automatically when the profile loads after I gave the user Full Access and SendAs permissions.
Thanks,
-John
