I have a very strange problem.

I am running the latest maemo release, running Excange 2003 with all service packs and updates.
I have my mfe account setup without SSL, using all other default settings.
I am connected via a very good 3G connection.
Syncing works fine.

I can send new e-mails ok, most of the time.
I can also reply to some e-mails, but only if they are very small, if it goes over a certain size it just sits in the outbox for ages and times out and fails after about 3 minutes. I am still experimenting to try and find the threshold at which it will fail. i also get the following error in the httperror log on the server:

Code:
2010-02-11 17:44:35 xx.xxx.xxx.xxx 30790 192.168.1.10 80 HTTP/1.1 POST /Microsoft-Server-ActiveSync?Cmd=Ping&DeviceId=<imeihere>&DeviceType=SmartPhone 400 1 BadRequest ExchangeApplicationPool
The kicker is: if i connect via wireless it works perfectly, all the time

any idea if this is a known bug or something wrong with my setup?

Thanks.
I notice the IP is 192.168.1.10... is that your local device IP on wifi? It doesn't seem like a likely 3G IP; if this is on 3G are you connected via VPN?

If you're mainly having trouble on 3G over non-ssl HTTP, it could be a broken transparent proxy they're forcing you through. Is there any way to use SSL with your company's exchange server?

What about setting up your own SSL proxy somewhere and using that? (ie. a server you have accessible from the 'net)
