ActiveSync does not ask if I want to establish a partnership with the 1945, but does with the 2795. When I connect the 1945, it tries to sync but fails to transfer the Contacts and the Calendar. It tells me that 433 items failed to transfer. The 2795 syncs just fine. The 1945 was originally synced using ActiveSync 3.7. Do you think this has any bearing on the problem? When I removed ActiveSync from my PC and reinstalled ActiveSync 4.1, the same thing happens, it does a sync with th 2795 but not with the 1945. The ActiveSync 3.7 will not install. Does this help any?
