hmmm interesting problem... Right, all my appointments are stored on my Outlook calendar at work. I can't get activesync to work with my server, so let's ignore that option. What I have been doing is using Google Calendar sync running on my PC to sync entries to my Google calendar. So far so good. Now initially, I synced my Desire to Google Calendar using the "Google" account in "Accounts and Settings". that worked fine. The entries in the Calendar app were given a blue stripe to identify them as being from the Google sync account. Now the fun begins. I wanted to start using Google's own exchange servers to get my email and when I added that as a new account, I saw I could also sync calendar via the google activesync account. So I tried that too and predictably I got duplicate and double entries (oooo-er) in my Calendar app. So I just unticked the Google calendar and used the google-exchange one instead. Now today I wanted to do some large scale tidying up and noticed that in my Calendar, I have entries (orange stripe) which are listed as "Exchange" entries but under the Calendar settings - there is no longer an Exchange calendar! All I have is PC Sync - nothing on that one And Google sync! (the blue entries) So how do I get rid of the exchange entries?? Hmmm just read my post above and admittedly may not be very clear, so apologies if this leads to more questions than answers!
