Exchanhe MAPI trouble

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.

    Please below review!

    1. IIS Manager -> Servername -> Worker process is duble click.
    2. MSExchangeSyncAppPool is duble click.
    3. Verify is Client IP.

      Thanks for the answer. I followed the indicated path. What should I have seen? I have two lines with identifiers.
