In our Microsoft tenant we have an Office 365 User with an Office 365 E3 license.
This user is member of a security group. This group has been used to restrict access to an environment to only the members of the group.
However the user is not visible in the Active Users view (or in any view for that matter!) (via Settings > Users + permissions > Users > Manage Users in Dynamics 365) (The user has been added weeks ago - this shouldn't be a sync problem)
The User is however able to log in to a Canvap app in this environment, since it's shared with the user.
What do I miss here?
