Here at work we’ve just setup Public IM Connectivity (PIC) on our Live Communications Server setup. Although it’s not my project I’ve been slightly involved as I designed the original setup here a few years ago.
The good news is that it all seems to work quite well, you can’t quite do everything you could if you had a full MSN client but its ok. One problem we did notice was that we couldn’t add external MSN contacts that were using EASI passport domains – i.e. a personal domain ‘xyz.com’ rather than the default ‘msn.com’, ‘hotmail.com’ etc.
So if you want to add ‘firstname.lastname@example.org’ to your PIC enabled Communicator contacts, you’ll need to add him as:
An easy fix to find, but I thought I’d post it up in case anyone has the same problem.
