Usualy domain users use there domain credentials ([email protected]
) to login to their SharePoint online (Office 365).
Now there are another users from another company (domain) which try to login to this SharePoint online. They have to use [email protected]
to be able to login successfully. Now they think the user name is too long and want to skip entering @theDomain.onMicrosoft.com
somehow.
Is there a way to skip writing @theDomain.onMicrosoft.com
?
I read this article, however I think we need to have SSO on.
