Our Exchange 2010 Edge is still getting this error message, and reject the message
421 4.3.2 System not accepting network messages
We have a few receive connector only one receive connector got this error.
I try to review all the log Protocol; connectivity log still no idea it just show this error
I already change the MaxInboundConnection and MaxInboundConnectionPerSource to 5000 and 500 on the Receive Connector
How can i overcome this issue. it make me a lot of trouble
