Activesync / Exchange delays? as items arrive doesn't always work

[jwoodall]

I have an Alltel Diamond and run Activesync to an Exchange 2007 server.

I get very unreliable connections with Activesync when it is set to "as items arrive". Each morning I should have about 20 messages that were delivered overnight, but they are not there until I run a sync manually.

Sometimes they won't arrive at all until I reboot the phone.

I have tried "every 5 minutes" with some success, but that doesn't work 100% either.

I am the Exchange admin of the system that I am using, so I am aware of all the standard troubleshooting stuff. (hard reset, reconfigure the account, etc.) It just appears that Activesync is not stable on the Diamond.

I don't have any other users complaining of the same issue (there are hundreds of users on WM6.x where I work), so I don't think the server is the cause.

Has anyone else had this problem?

Is there a solution?

Thanks!
