Today something very bizarre happened, 95% of my calendar went missing. My setup for syncing is not simple, but it has been working flawlessly for the last several months. Just before boarding the plane today, I noticed my calendar was missing. I looked at my blackberry last sync log it was saying 89events deleted. needless to say I was sweating. I don't know what went wrong, what I did wrong, or what conditions the software figured it could just go ahead and delete. Somehow my google cal got into this state where it thought all the appointments in outlook were to be deleted, and so the sync deleted them. Thank fully Outlook has a trash, and I was able to sort deleted items by type and I think I was able to undelete all the events that were deleted, but i will never know until the said event is supposed to happen. Anyway I had to reset the sync - re-upload all my outlook into google, and re-set my bb to re-download all my google data, and now we seem to be back to normal... I think.
