When Froyo came in, I noticed the Exchange calendar became `combined' with the Google calendar. This was a bit alarming, as I don't use the Google calendar and the Exchange account completely disappeared. I re-setup the Exchange account and spent some time coaxing it to sync the calendar. Every few days I get a notice that the email service requires a FC and the Exchange account disappears. Start again from Go. I have Sync turned off, as well as auto app sync. I do not pull mail unless I need it. Calendar and Contacts are set to sync when I turn on Sync. Not sure if this impacts anything but this only started after Froyo. Getting tired of replacing the Exchange acct. Thanks.
