This tweak is very useful when you going to recreate a pairing with a desktop Outlook (on Vista)... if you don’t delete all these things from your mobile device before connecting it to your desktop, all the things will be merged. Also, if you have the same entries on the mobile and on the desktop, those entries will not be synched after the pairing.

You will need the .net Compact Framework 2.0 SP2 in order to use this application.

Please note that in order to install CAB files you need to copy them into the device and then, from Explorer, tap on them.

Important information:
The installer does NOT create a shortcut in the program menù, this is a known bug for ther version 1.0. In order to run the application you need to open explorer, navigate into the "Programs > PocketOutlook Eraser" directory and tap the "PocketOutlook Eraser" file.

Update Description:
v1.1:
- Resolved problem with shortcut, added ability to send feedback and bugs.

v1.0:
- First release.
