General Background Information:

A user in Business Central must be first added to Office 365 and assigned a valid Business Central license.  This adds the user to the list of users in Business Central.  A user must have valid permissions granted via permission sets to the expected companies for the user to login.


To add users in Business Central, your company's Office 365 administrator must first create the users in the Office 365 Admin Center. For more information, see Add Users to Office 365 for business.
