Hi
I have upgraded a customer from Exchange 2003 to Office365.
All this has been smooth.
I can now setup Outlook anywhere from example a homecomputer and all are configured correctly
Customer is running a Windows Server 2012 Essentials and I have Connected the domain With the Dashboard and all seem to be working.
But I can setup Outlook for the users, it keeps asking for the username and password
Please give me some hint to solve this issue
