Member of specific Team can't be added to Schedule

Copper Contributor

I've been trying every which way to get this to work. Office 365 Admin, Azure Directory, Sharepoint Site, everything.

 

I have a few team members that will not come up in the Add People to Schedule box. Despite being in no other Team or on any other Schedule, I cannot get them added to the Schedule that they're a Team member of.

 

Even making them Team Owners has no effect. It appears random and only affects a few members in differing Teams.

 

Any ideas?

How about removing a user and re-add that user to the Team. Can you try that?
Already tried. Using all the different methods for removing from group that I mentioned above unfortunately.
