Searched the forum but couldn't find anything on this. I have my (non-rooted) Motorola Droid set up for Active Sync with my company's Exchange 2007 Server, using the stock Email and Corp Calendar apps. All was working fine until yesterday. I got a triangular "Lost Connection" notice in the notification bar and was offered a 'Resync" button. Without thinking about the implications, I did the resync. Now all my calendar items are duplicated in my Corp Calender, even past ones. Only occurs on the Droid; both my desktop Outlook and Exchange webmail display the calender correctly. I assume that my entire calender got "re-downloaded," thus the duplicate entries. Emails have not been duplicated, only the calender. I've been researching this but haven't come up with much. Is there a way to remove the duplicates or reset my Corp Calender without having to remove and reconfigure the entire Exchange setup? Any and all suggestions appreciated.
