Gmail Group Emails

Hi all ... new guy, switched over from a blackberry and while I'm happy, there are some pieces of functionality I'm confused on.


Created a group email list, all members have email addresses, otherwise it'd be pointless


When I try and use the group, the Eris says 3 of the people don't have email addresses. Odd because I can see online in GMAIL and also on the phone that all of them do.

Have forced a sync on contacts and groups already, doesn't resolve it
