For the last few days, I haven’t been able to get my most used mobile device: My Windows Mobile Smartphone to sync with the Exchange server. I kept getting error 0×86000107. The way I fixed it this morning was to deselect the calendar from the Exchange Server sync options, let it sync, and then add it back. Voila – now I’m back in the saddle with my Smartphone! I’m posting this here because although I found a few options for troubleshooting through seaching Google, nothing else worked for me. Maybe this will help someone else one day.
I hope you licked it because it could rear its ugly head once you sync with the “other” computer. Or so most of these problems with 86000107 happen, syncing between two computers.
