I recently got a T-Mobile, MDA Compact II with windows mobile 5 and a generous GPRS option as part of my plan.

One of the first things that I wanted to do was hook up my Gmail account.. but found to my dismay, that it didn’t seem to work quite right. Messages would be downloaded and not displayed, or deleted on the next send/receive, or worse - just seem to do nothing at all.

Most of the various solutions I found online involved setting an option in my device to “download headers only” and download a large amount of the body (eg 999 kb). This solution had limited success in that I semed to read through a large number of headers, but still didn’t end up wiht any messages.

I decided to connect to my gmail pop using outlook to try and see what was going on. It turns out that I had a huge amount of email on my pop server (I have set gmail to provide all emails via pop). Something in the order of 300 mb - and all unread. I deleted all of my old emails from the gmail pop server… then removed gmail pop from outlook. Wow now Gmail seens to be working on my device!!! Hooray!

Hope this helps someone.
