BES Calendar wipe

I have a user who was just recently added to our BES, but now he has duplicates of all his calendar entries. One for the Desktop calendar (The one that syncs to the BES) and the old calendar (the one that doesn't sync).

Anyways, after browsing on crackberry one of the solution is to go to the calender options and type in "wipe". The message states that it'll wipe out all entries for all calendars. Will this wipe out calendar enties that is on the BES? I'm hoping after it would just resync with the BES to get all the entries back and not have dupes from the old calendar, but I'm afraid that I might wipe out all the data all together.

Anyone know if this method would work without wiping out all the data on the bes as well??

thanks in advance.

Anyways, I went ahead and did an wipe, then immediately typed in RSET to reload the data from the server, and everything is back to normal.
