We are running Exchange 2013 with a Windows 2012 Domain Controller.
The on-premises I.T person did the following:
1. Created Active Directory account.
2. Created an Exchange mailbox and associated it with the AD account.
3. Now, this is where things went awry. The I.T admin deleted the mailbox, and then created one again.
Now when users email the user, they received an NDR message – please see below.
I know that certain times like this, an X500 address needs to be created or edited, or at least I think that’s the case.
