Good afternoon!
The Exchange 2016 server freezes periodically and stops working for several minutes for all users. In the Windows log events, there is a “Warning” with event code 2002 “The number of outstanding requests for guard TargetBackend has exceeded the max limit 150.Current request will be rejected”, which occurred when Exchange hung. Please help me understand who is the source of the warning.
