iPhone and ActiveSync: Message received

So... the user received my test email ...

I think the order of checks if you have problems with iPhone and ActiveSync on Exchange:

1) Check the ActiveSync is working using Microsoft's Online Test Tool
2) Switch on Proactive Scanning and Background Scanning in MSExchangeIS\VirusScan.
3) Check timeout values on all routers under your power. If possible, make the value greater than the MaxHeartbeatInterval registry setting in Exchange. (See previous post). (If not possible, perhaps make the Exchange MaxHeartbeatInterval just lower than the router timeout?)

No doubt he'll update to iOS4.1 soon and we'll get yet another problem...
