We have an issue in our front end server which redirects OWA and activesync requests. The server has only 700MB memory. Notice high memory utilization for w3wp.exe process and the page file utlization is also quite high. OWA and activesync stops working at a particular time daily. The only fix is to restart the server.
Getting event 3007
Exchange mailbox Server response timeout: Server: [server name] User: [user email address]. Exchange ActiveSync Server failed to communicate with the Exchange mailbox server in a timely manner. Verify that the Exchange mailbox Server is working correctly and is not overloaded.
Also getting the below event: 3014
The Exchange mailbox Server[Server name] has reached its timeout threshold. The mailbox server will be protected from new requests for  seconds.
