Sometimes when I reinstall my PC get a new Work PC or buy a new home PC ,ActiveSync, now the Device Center asks me to delete an existing partnership to setup a partnership with the new PC, since only two partnerships are allowed.

When I delete that partnership all contacts that originally came from that partnership get deleted too. How can I prevent that from happening. Do I really always have to remember to frequently backup all my contacts in a safe place? How much redundancy is needed. I hat them on one of my PCs and on my phone.

Go into root of your device and make a copy of *.pim file. Delete partnership and you will notice that there are no contacts any more. Restore saved *.pim file and your contacts will reappear.

Do notice that sometime you will get "file in use" errors when replacing *.pim file. Just reboot your mobile phone and try again.

If you do not see *.pim file in root of your phone, download some file manager.

That works. Allthough it is too late for me now. Why (oh why) is this implemented that way? Do you happen to know how I can make my phone and ActivceSync/Device Center FORGET that the contacts once came from a PC and breakup the association? – bitbonk Jul 28 '10 at 7:11
Only method of forgetting I know is this one. I am not aware that you could "disconnect" contact from it's source any other way. – Josip Medved Jul 28 '10 at 7:47
