Ok, just substitute Outlook with whatever app holds your contacts list to which you sync. I guess you use a hardwire or wireless to connect to the PC. So do the same like you might if you had BT.
BTW, I think the Outlook contact field that syncs with my phone is the "mobile number" field. My point before was to use the same field so that Phone Link looks in the correct place in whatever contact manager you are using. Interestingly, I think Phone Link needs an intermediary to access your phone. So could the problem be that the intermediary isn't kosher in Microsoft's ecosystem?
Have fun.
