Internal email flow affected for few users
Hello All,
So few days before we had a power outage and exchange 2013 server went down. When power was restored, we had database in dirty shutdown. We repaired the database and users were able to access emails. however, there were 2 mailboxes that showed quarantine. I ran a repair request on those mailboxes, but still, it didn't help.
Finally, I disabled their mailbox after taking PST and created a new mailbox for them. Now they were able to access emails from the new mailbox. External send receive from these emails works fine.
However, when any internal user emails them they receive NDR. Even the two user cant send emails to each other internally.
IMCEAEX-_o=First+20Organiz
Remote Server returned '550 5.1.1 RESOLVER.ADR.ExRecipNotFou
i tried to remove the autocomplete email from outlook and they fixed the issue for a day, but the same situation now. I tried to send emails from owa and it works fine.
I think there is some problem with x500 email addrerss.
Can someone help to find a resolution for this?

As mentioned above, you need to add custom X500 address into both new mailboxes. After which your issue will be resolved. You can find X500 address in bounce back mail.

@Hayes: most of the clients are usign outlook 2016 and 2019 so the NK2 file is not there to fix the issue.
@Amit: can you please explain me what will be the X500 address for me if i receive the following NDR
