Hi!
Just installed GroupOffice 2.18 following the wiki.
When users log on for the first time, they have to fill in their credentials. E-mail is greyed out, because it uses their (correct) SME server mailaddress. Yet when they try to save it, the error 'E-mailaddress is not valid' comes up. So they cannot login.
I can login, so can Admin. I reinstalled it because it got deleted. But the old users are still there. Maybe this has anything to do with it. Any idea?
