Mail from a particular mail-enabled public suddenly starts bouncing after decommissioning Exchange 2003

Whilst public folders are now accepted as a bane of most administrators, they are still being used in a lot of organisations because…well…it’s a free but messy solution for company information management. Unfortunately, I still have to administer them in my organisation.

I recently started seeing NDR’s to a particular mail enabled address:

#< #5.2.0 smtp;554 5.2.0 STOREDRV.Deliver.Exception:ObjectNotFoundException; Failed to process message due to a permanent exception with message The Active Directory user wasn’t found. ObjectNotFoundException: The Active Directory user wasn’t found.> #SMTP#

A quick search led me here

The dreaded remnants of the old Exchange organisation. Sure enough, within my ASDI Edit search, I had to remove the ‘Server’ container.

This fixed my issue instantly. A test email delivered immediately.
