Active Sync 3.7.1 -- Outlook 2003 -- Ipaq 3955

I am working my way through an active sync problem, of which there seem to
be many in this forum.

The very first time I connected the Pocket PC to the laptop and stepped
through the setup the device synchronized the inbox and contacts from the
Exchange 2003 server at the office. It did not sync the calendar. Every
attempt since then the sync of the contacts, inbox and calendar fails with
Internet_31 as the reported error.

There is a good and stable connection between the pocket pc and the laptop
at all times. I can use the browser on the pocket pc with no issue and it
will sync items from the laptop. It is the sync with the Exchange Server
that won't work.

I have tried this will mutliple PC's, all with the same result or nearly the
same results. Active sync doesn't seem to work reliably.

I can get a reliable update of the inbox by switching it to IMAP. That
works all the time. However, I really want the calendar to work and so far,
that isn't happening.

If anyone has had similar experiences and managed to troubleshoot them
please weigh in.

Thanks very much.
