Hello everyone. We had an exchange server running 2 accepted domains lets say Domain-A and Domain-B. domain b split off and went to a hosted solution. We removed the accepted domain, made sure all smtp addressed for Domain-B were cleaned up and all seemed okay. There is only one under still setup on both our internal exchange server on Domain-A as well as the hosted exchange server that Domain-B moved to. That user is the owner of the company so we need to try and fix this as soon as possible. He has a problem where he tries to send to himself a test from Domain-A to Domain-B and he gets an undeliverable message. If you look at the message (which I have included) the error is "IMCEAEX-_O=Company_OU=EXCHANGE+20ADMINISTRATIVE+20GROUP+20+28FYDIBOHF23SPDLT+29_CN=RECIPIENTS_CNfirstname.lastname@example.org
#550 5.1.1 RESOLVER.ADR.ExRecipNotFound; not found ##"
It's taking his email@example.com to address but trying to send it to an address that is firstname.lastname@example.org which does not exist anymore. To try and troubleshoot I thought maybe his outlook client was caching it somewhere so I had him delete the auto generated email for email@example.com in his outlook history but when he types out the address to recreate the cached address it does the same thing when he send the message. Is this being pulled from the AD schema or something? I'm not sure where this is coming from. The full error is listed below. Thanks for any and all help! cheers
