I have a mailbox on an Exchange 2010 server running Windows 2008 R2. I noticed that I have a mailbox that is selectively rejecting email. Some email will be accepted by the mailbox and show up, but other email does NOT. The mailbox was
set up to not reject any email so the email should pass through.
I am only seeing this on this mailbox and not on *any* other mailboxes in the organization. I can send the same email to other mailboxes and the email shows up immediately, but if I send that email to that mailbox I will sometimes receive the email and sometimes I won't. In addition, sometimes the Exchange server will kick back a undeliverable message even though that message was delivered.
Please advise
