A Windows Mobile 6 device may encounter a situation where partnerships with two separate PCs exist, but are recreated each time you change from one PC to the other.

This article describes how this issue can be resolved.

Warning: This includes modifying the PCs and the devices registries. Unintended changes to the registry may render your PC/device completely inoperable.

Under some rare circumstances where two partnerships are used, ActiveSync partnership settings on a Windows Mobile 6 device may become unstable. A single partnership seems to work well, but if the device is connected to the second PC, the device tells you that it does not have a valid partnership with this PC. You have the option to create a new, fresh partnership. If you do this, and then reconnect the device to the first PC, the same thing happens over there.

Though it is possible to recreate partnerships each time you change from one PC to the other, an effective synchronization between the device and both PCs is not possible.

Deleting all partnerships on the device or the PCs, as well as reinstalling ActiveSync, do not solve the problem.

To resolve this issue, all references to the defective partnerships must be completely deleted on both PCs and on the device itself.

You need a registry editor for Windows Mobile 6. We recommend CeRegEditor by mdSoft. This tool does not require installation on the device itself, but only on a PC. And it includes a soft reset function which is very useful.

CeRegEditor can be downloaded here: http://ceregeditor.mdsoft.pl/

If you have a registry editor installed, follow this procedure:

• On both PCs:

• Use ActiveSync to remove the partnership to the respective device. Partnerships to other devices may be left as they are.

• Using Windows Explorer, open the "\Documents and Settings" folder, open your own subfolder, then navigate to "Application Data\Microsoft\ActiveSync\Profiles".

• If there is a subfolder with the name of your device, delete it.

• Open regedit.exe and navigate to the following key:
  HKEY_CURRENT_USER\Software\Microsoft\Windows CE Services\Partners\

• There may be one or more subkeys with names like "17b8599f" or such. Check "DisplayName" inside each key. If it matches your devices name, delete the subkey completely.

• Reboot the PC to properly reinitialize ActiveSync.

• On the Windows Mobile device:

• Use ActiveSync to remove all partnerships. Try the menu item "Options", then select each partnership and use the menu again to delete.

• Use your registry editor to navigate to the following key (on the PDA's/smartphone's registry, NOT on the PC's registry):
  HKEY_CURRENT_USER\Software\Microsoft\ActiveSync\Partners\
  If you use a PC based registry editor like CeRegEditor, you need to connect your device to the PC first. A partnership is not needed, since the registry editor also works in guest mode. If you use a registry editor that is installed on the device itself, a PC connection is not needed to change the registry.

• There may be one or more subkeys with names like "{261675C1-195B-445A-8AE8-3CC763823373}" or such. Delete all of them completely.

• Navigate to the following key:
  HKEY_LOCAL_MACHINE\Software\Microsoft\Windows CE Services\Partners

• There may be one or more subkeys with names like "P1", "P2" or such. Delete all of them completely.

• Perform a soft reset of the device. If you use CeRegEditor, you can use the built-in soft reset function.

After completing all the steps above, you should be able to establish two properly functioning partnerships, as with a new device.

Warning: Recreating the partnerships may lead to lots of duplicate elements. You may want to delete elements on the device and/or on the PCs prior to recreate the partnerships. We recommend to backup all data before starting the above procedure.
