As of April 20, 2020, the number of Office 365 users is increasing rapidly worldwide, and there are delays in functions such as team member registration of Teams.
Inviting students to a group created by faculty and staff does not complete registration.
Or, if the registration is completed and the student cannot see the team even if they open Teams, it is possible that the reflection is delayed, so please wait for a few days.
If that doesn't work, please contact the following address from the staff member who manages the group.
In that case, please fill in the following information.
