Duplicate Contacts/Calendar... ugh!

[akarol]

So, I started with a clean slate last night after finally getting my EVO rooted and since my Exchange server was down, I decided to sync my contacts and calendar via HTC Sync. However, today, the Exchange server is back online. Now I have duplicate calendar events and Contacts on my phone. How can I delete all my HTC Sync contacts and calendar events? I know I can Hide those items via VIEW, but I'd rather remove them completely from the phone.

Thanks in advance...
