You can now use a dot in the email alias. We are working on providing the ability to edit the email address of a group after creation.

I agree with Dan Holme, but I do not want my users to be able to select from a list of domains. I want, as a global admin, the ability to designate the default domain for Groups separate from the tenanat default domain. I want all tools that use a "default domain" to have a configurable setting as to what the domain is so each could be separate (IE: Groups = groups.rootdomain.com, Distribution Lists = lists.rootdomain.com, etc).
