I am having the same problems except connected to Exchange 2003. When offline
the calendar entries just dissapear. I have tried all the above. Online works
fine as do windows mobile phones. I have also stopped the AV scanning the OST
file just to make sure. Any other ideas please?

Thanks again, but I found the solution (see earlier post): I had
misconfigured my account. Solution was to:

Log into the email domain's Control Panel page on the Exchange 2007 server

Go to Configuration & Administration Exchange Mailboxes your_mailbox

Click on Edit

Change "Show in address book" to Yes
