Unknown users: Why some guests appear as unknown

[lfgdp01]

I'm a Spanish teacher and we are using Teams for our lessons, because the town I work in is closed up.

For some reason, many students appear as Unknow Users even if they have introduced their names. Others aren't let to introduce their names.

It is important for us to know the names of our guests. Lately some students get into classroms the don't belong in. We should be able to send them away, but they are Unknow Users.

This issue should be corrected, or we will have to move to another platform.

Thanks for listening.

This is a longstanding issue (or a series of issues), the best thing to do here is open a support case and report it, so that Microsoft can (hopefully) fix it.

A work around while waiting for a fix is clicking the “participants” button in the meeting and then going back to chat. This usually updates the unknown users names. Assuming you are talking about in meetings.
