Linked Mailbox and account rename

Posted on 2014-04-25
Last Modified: 2014-04-28
I had two users.  User One left and User two took over from the fist one.

User One was the master account as a linked Mailbox
User two had his own mailbox.

I deleted User Two and his mailbox
I renamed both the linked account, and the disabled account that are associated with the mailbox

User One can now send from outlook, but the reply email address still shows that of the account PRIOR to the rename.
Other users can email user one from external and OWA, but not Outlook.  They get a 550 5.1.1 Recipient not found.

Double checked all accounts (EMC and AD)
Checked Alias
Checked email Address in EMC
Rebuilt Address book
Restarted Address book service, sys attendant, Exchange mailbox assitant

Any idea's what I missed ..... out of idea's

If I understand correctly, you have deleted User2 and renamed User1 as User2. Now when Outlook users try to email User2, they get an NDR. This is due to Outlook caching the legacyExchangeDN of the old User2 mailbox. This issue is described in my article here -

To resolve this issue, you will need to add an X500 address to the mailbox, which matches the legacyExchangeDN of the deleted mailbox.
