I have an exchange account where I keep all my contact info. However, I've noticed that IM screenname info that I input doesn't seem to work properly. On my Pre, it is labeled as IM, instead of AIM. And when I click on their screennames from my Pre contact pages, it gives me an error stating that the "specified IM type is not supported." I think the problem is that I only list their screennames on my exchange account, and not their AIM association. But does anyone know how to label an IM as AIM with exchange? Thanks.
