Its telling me that an address in which I'm sending or replying to is an "invalid address". Its still giving the red X even if I try to initiate or reply. In fact I tried to forward a message just to another member of the staff yesterday and it bounced back with the red X, saying their email was invalid. I and 2 others are all having the same problem, now. Should I consider just going "old school" with one of the old Motorola brick phones?
P.S. And we all don't have it happening to the same email addresses.
