I had an issue logging into my work exchange account, so I had removed the account from the Preferences & Accounts screen. When I added the account back, I now have duplicate mailboxes, calendars, and email folders.

Without resorting to a full erase, is there a way of removing the duplicates?

I'm wondering if I'm running into this due to Synergy having what it thinks should be the active exchange account and throwing that back in?
