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, "Enterprise Firewall Configuration for Exchange ActiveSync Direct Push Technology" (

I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

No big problem. This means the push email will not be working, rather than ActiveSync clients getting alerts the very second an email lands in their inbox, it will need to be polled.

"Push" in this context is really more of a "slow pull", when a client requests an update, Exchange just leaves the TCP/IP session hanging, until an email arrives. A lot of firewalls time out partly established TCP sessions, this generated he event log message you see.

Not sure with a Fortigate, but this looks good: 0 73772977

Personally, I have never bothered, the way that ActiveSync implements a "push" is pretty dodgy IMHO.
