Has anyone else noticed that they can't sync Google Gmail via Activesync over the past few days? At first I thought it was just me but soon came to find that the "Error Synchronization" message was being displayed on other Windows phones.
The official error code is 0x8600050c (Communications Error) and in looking over at Google Mobile's Help Forum, there are a few solutions available.
The first suggestion is to delete the current Exchange Server relationship and re-create it. Another solution suggests to un-check the email option in Activesync, reboot the phone, re-check the email option and sync. The latter seems to have the most success.
We couldn't find anything official from Google on the cause of these errors or of a "official" solution. If we hear of anything we'll pass it on.
