Hi there,
a customer of mine has several sites with Exchange 2013 CU18 to CU21. Between two sites there are smtp transport problem. Sometimes Emails get stuck in the queue of the sending server, smtp errors
4.4.1 and 4.4.2 ( cannot reach other server and email dropped ).
The customer is reporting, that there aren't any network problems between those sites.
I searched for transport related events - and to my surprise all related servers are flooded with eventid 16022 "a forced configuration update for Microsoft.Exchange.Transport.TransportServerConfiguration
has successfully completed". - every 2 to 5 minutes a new event...
My be, that these two incidents have nothing in common...
Yours
Franz-Georg
