Exchange mailbox Server response timeout: Server: [] User: []. 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.

Unexpected Exchange mailbox Server error: Server: [] User: [] HTTP status code: [409]. Verify that the Exchange mailbox Server is working correctly.

The Exchange mailbox Server: [] has reached its timeout threshold. The mailbox server will be protected from new requests for [60] seconds.

The average of the most recent [200] heartbeat intervals used by clients is less than or equal to [540].  Make sure that your firewall configuration is set to work correctly with Exchange ActiveSync and direct push technology. Specifically, make sure that your firewall is configured so that requests to Exchange ActiveSync do not expire before they have the opportunity to be processed.  For more information about how to configure firewall settings when using Exchange ActiveSync, see Microsoft Knowledge Base article 905013  -We are not using an ISA server

It turns out that there was some old mailscanner applications installed that I uninstalled that were inteferring with IIS, also rebooted server.

How did you determine that it was the mail scanner app that was interfering with IIS? I am also running into this issue and have received about 159 errors just today its 4pm now.
