Some users report being unable to email another user.

I have a few users who are reporting that they are getting an undeliverable report indicating that the account can't be found when they try to email a specific user.

Most employees are able to email this user, but a small group of employees get an undeliverable message when they try.

I have had the effected users re-download the GAL into Outlook. But it made no difference.

I have attempted to trace the emails that failed to deliver, but they do not even appear in the originating mailboxes.

Everything I can see on the account in question shows that it should work, and I am unable to locate anything in any of the logs that even refers to AD account/mailbox in question.

I have included a couple of the undeliverable notices below so that you can see what I am seeing. Important information has been redacted of course. But all server and user account names are correct.

Have you had the users delete the problem user from the outlook type ahead cache (start to fill in the username in the TO box and when it appears press delete)?

You could provide more detail about the format of the problem account. Has the mailbox been moved, name changed?

This:
IMCEAEX-_O=RES_OU=EXCHANGE+20ADMINISTRATIVE+20GROUP+20+28FYDIBOHF23SPDLT+29_CN=RECIPIENTS_CN=TARGET+20USER@DOMAIN
#550 5.1.1 RESOLVER.ADR.ExRecipNotFound; not found ##

Normally means either a typo or there is an old address in a cache somewhere.

Perhaps also download the WHOLE address book, not just the changes.

They have downloaded the full address book, and that has not resolved the issue.

The name in the UD report is spelled correctly, and the account has not been moved anywhere since the 18th of last month. That being the last day that email from the users reporting the problem was successfully delivered to the user in question.

Examining the system logs from that time reveal nothing.

I have asked the users having the problem to try deleting the pre-cached name and try again from the GAL, but I have not heard back from them yet.

Apologies for the delay in closing out this ticket, I am working with guys in the field and they can have spotty access.
