On Exchange 2013/2016 You may Receive an Error like :
The number of outstanding requests for guard TargetBackend("ServER_Name.fqdn.local") has exceeded the max limit 150. Current request will be rejected.
The Solution :

After this change recycle the MSExchangeSyncAppPool and MSExchangeRPCProxyAppPool in IIS manager (if you have more then one server I recommended to take a delay of 5 min between Servers ).
