Ambigous Address issue Exchange 2010

Hi All,

Got an issue with an ambigous address issue in exchange. Whenever someone sends an email to (for example) 123@123.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?

Cheers,
Grant

If you don't use public folders, then yes it can be deleted or mail disable the PF

I recommend removing the PF through the EMC/EMS though

The address in question does not appear in the Global Address Book and doesnt appear anywhere in the exchange public folders. The only place it is visible at all is in the Microsoft Exchange System Objects OU. So It's not really possible to mail disable it.

The error means that there are more than one accounts that has the same address and Exchange is confused.

Delete the duplicate address and things will be fine.

Hi Rajith,

Thanks, but I'd already figured that part out. My problem is knowing if it is safe to delete the object within the Microsoft Exchange System Objects OU or if this may cause issues.

Thanks,
Grant

Have you tried the EMS command I posted?

Hi,

Yes, I tried the EMS command and got an error that the public folder did not exist.
