I recently migrated from exchange 2003 to exchange 2010. I decomissioned my exchange 2003 server about a month ago. Today after rebooting my exchange 2010 servers, mail enabled public folders stopped working. I get the following kick back when I try to send an email to my mail enabled public folders:
Delivery has failed to these recipients or groups:
The e-mail system had a problem processing this message. Exchange will not try to redeliver this message for you.
Diagnostic information for administrators:

Any ideas on what is causing this? Thanks.
