Pc outlook data to 2215 device activesync

There is a setting in Options>Rules> Conflict Resolution which states:
Desktop: with the options:
- Leave unresolved
- Always replace the item on my device
- Always replace the item on this computer

That is what I was refering to.

I assumed you changed the same appointments on your Laptop as were already on your device and you had "Always replace the item on this computer" selected.

If this is not the case then I would do the following:

Delete the current partnership on your PC. (When not connected) Open ActiveSync and go to File>Delete Partnership (save the files when it asks).

Then soft reset you iPaq and connect - during the connection wizard it will ask you which you want to do use the items on your PC/ Device/ or Combine choose which one you want.
