I'm not the Google Apps Admin but he wants me to create a gmail account and add it to chat so that everyone else in the domain can talk with this gmail account.
The problem I'm having is I that most of the invites aren't showing. I've sent an invite from firstname.lastname@example.org to email@example.com, firstname.lastname@example.org, email@example.com, etc. and only the accounts from the IT department have the invite show up from firstname.lastname@example.org
Now I just want to know if there's a setting that blocks chat invites from outside the domain? Because if there is, I think he probably enabled it since he restricts a lot of other stuff.
