I have a BB 9900 and have just started using Outlook calendar for work. I am using the BB desktop application to sync them.  It synced great for the first 2 months and now my latest sync I cancelled still wiped my entries from my phone. I took a chance and tried to sync again and when I synced it it wiped it all from my outlook calendar also. I have not changed any of the settings on either my phone or outlook. I was wondering if I just missed something that maybe wipes it out after a certain period of time? Is there any way I can recover the entries?
