We have a single Exchange 2010 SP2 RU5-V2 server and 2 Edge servers.
We use mail enabled public folders. This was working fine untill we recently added a new (3rd) Domain Controlller in the Exchange site. We now have an issue that messages received from internal users to some public folder are rejected at random. I suppose the "random" factor is when the new DC is used for authentication. When we exclude the new DC with Set-ExchangeServer -StaticExcludedDomainControllersthe problem is gone. When we enable it again the problem is back. When we add a new 4rd fresh DC the problem is back again, to be sure it was not a corrupted server. The third DC is a physical machine. The fourth DC we tried was a virtual machine. So I don't expect any hardware, netwerk or firewall issues. The firewalls on the DCs are disabled. Looking on the EventLog at Exchange or DCs does not show anything particular. I know the error looks the same like a spam reject but that is not in case. It looks like some kind of authentication failure, but I wouldn't know how to fix that.
Some months ago we already remove the old Exchange 2003 "Server" with ADSIEDIT which is a common issue:CN=Servers,CN=First Administrative Group,CN=Administrative Groups,CN=First Organization,CN=Microsoft Exchange,CN=Services,CN=Configuration,DC=domain,DC=local
I hope anyone can help!
The error we see in the reject mail to postmaster:
