User gets NDR #550 5.1.1 RESOLVER.ADR.ExRecipNotFound when she receives any email
Hi Experts -
This is a weird one. I have a user that is getting a bounce back when she receives email from internal senders. The senders do not get a bounce back however. So if I send her an email, she gets the original email, but then she immediately gets an NDR with error "#550 5.1.1 RESOLVER.ADR.ExRecipNotFou
From: USER.NAME <USER.NAME@DOMAIN.com>
To: USER.NAME
<IMCEAEX-_o=COMPANY+20NAME
As you would expect, this appears to be an issue with caching (The IMCEAEX string leads me to believe that), but nothing I try is helping the situation. I've cleared her NK2 file, added her LegacyExchangeDN value as an X500 address, and quite a few other little things in hopes to fix this. Nothing has worked.
Remember, this happens when she receives an email, not when she sends one. I had the assumption that maybe some how her email was being forwarded to an old/non-existent account of hers, but everything is clear as far as I can see. No delegates assigned, no forwarding set up, etc. Any help here would be hugely appreciated. Thanks!

It is possible what you could do is check her mailbox using MFCMAPI
https://mfcmapi.codeplex.com/
Another thing you can try is moving her mailbox to another database and see if that corrects the issue. I know it sounds weird but moving a mailbox has corrected similar issues like this in the past. If all else fails what you could do it export all of her mail to a PST, create a new mailbox and then import the PST into the new mailbox.

Ok, I will give MFC Mapi a shot, and move her mailbox to a different database. I'll post results when I get them. If there's anything else anyone can think of, by all means, throw them at me.

The user did in fact have a corrupt rule. Once removed, the issue went away.
