Receiving error code 0x8600050C while trying to sync with your gmail from a windows mobile device? (Microsoft Exchange Push Mail with Google Sync)

I fixed my error following instructions bellow:
Start > Programs > ActiveSync
[Menu] > Options

Turn off the “Tick” mark for E-mail.
[OK] (in top right corner)

Choose “OK” on the “Remove all Outlook Email” message.

[X] (in top right corner)

Reset your device.

After restarting, repeat the same steps, turning the “Tick” mark for E-Mail back on.

You should now be fine to sync again.
