Emails to Outllook.com members of a group
I have created a group for my authors for my site. I have added group members and for the first couple of days everything was working well.
Now the members of the group that use outlook.com (Hotmail, live) email don't get any emails. Even when I delete them from the group and re-add them, they don't get any confirmation messages. Other members that use organization email or Gmail and Yahoo get the emails just fine.
