Thousand of multiple calendar entries

I did a one way sync FROM DEVICE TO OUTLOOK and now I have all my calendar entried duplicated 5 or 6 times.  we are talking aboout almost 20000 entries.  I have no back up so restoring to a previous back up won't work.  I checked on my handheld and i only have one calendar so I don't know now what to do.  Can anyone help me?

Re: Thousand of multiple calendar entries

Hello -- and apologies for the delay.

Since you have no backup (your error, btw...), your only choice is manual. Use Outlook to cleanse your data and then re-synch one-way to the device. Be sure to keep a backup of your clean data (a PST works quite well for this purpose).

Good luck!
