HTC mobile - ActiveSync not working

December 2016


I can no longer sync my HTC TynII smartphone, hence unable to download my email, applications or synchronize contacts ...

Here are the instructions that I get when I try to connect the device with the PC:

Microsoft ActiveSync

  • Synchronization failed.
  • Reconnect and try again.
  • If the problem persists, see "Troubleshooting Microsoft in Microsoft ActiveSync Help on the desktop computer.
Troubleshooter for ActiveSync
  • Progression ...
  • Results: A known problem detected
  • Unable to obtain an IP address for the device.

What happens is that the phone is not being recognized by Activesync, follow this manipulation under Windows Vista and XP (for Vista - Windows Mobile Device Center):

Connect your HTC mobile to your PC. Wait until the sync to start and if there is any error, go to start> setting> connection> USB to PC and uncheck the "Advanced

features" and it should work.
