Got an issue with an ambigous address issue in exchange. Whenever someone sends an email to (for example) email@example.com. The item gets held in queue with an error:
"Last Error: 420 4.2.0 RESOLVER.ADR.Ambiguous; ambiguous address"
I've located the object with the conflicting email address, and it is located in AD users and computers under the Microsoft Exchange System Objects OU, listed as a public folder. We've recently switched to Exchange 2010 and have stopped using Public Folders.
What I would like to know is if it is safe for me to go into ADSI Edit and delete this object. And will this resolve the email ambiguous email address problem?
