I have set up a trial site and been forced to create a domain called mycompany.onmicrosoft.com
Now I come to set up users (We don not use Office 365)
When I try to add a user I have to set them up with the email address of
username@mycompany.onmicrosoft.com and I want to set them with with their normal work address (username@mycompany.co.uk).
Previously when I set this up for my old company I could create liveID's using the normal email address, but it all seems to have changed now.
The long and the short of it is that I have now set up my users on my trial site but they can't logon unless they use the onmicrosoft.com email address.
