FIXED my problem... mine was crapping out while syncing record 233 of 1924 Outlook calendar records. I tried the GIF work-around above but had no luck.

I finally went into Windows and created a SAVED directory under "C:\Documents and Settings\`userid`\Application Data\Research In Motion\BlackBerry\Intellisync" and moved all of the files and directories into that directory.

Then I plugged in the BB and did another sync... it didn't know who I was so it went through the dialogs of adding a new user, ie, choose Outlook and sync calendar stuff... When I synced - it friggin worked with no errors.

What a pain to debug - but at least for my particular device... it's now working. Hope this workaround is the shiz for others having Outlook calendar sync problems.
