If you want to participate on Teams as a guest for a job search or joint research, the procedure is as follows.
If there is a participation URL, access it and participate
If you need to register as a guest in advance, inform your @u (@un) account to the person in charge of the Teams who are hosting the event.
* When you inform someone of your Teams account, teach them your @u address （not @s）.
You can participate as a guest account even with a @s address.
However, if you are using Teams with your university account (@u), you will need to sign out first.
If the @s is registered as your email contact for job searching or other activities, the organizer may register that address (@s address) as a guest.
We do not know about Teams outside of the university, please be aware of the above mentioned and contact the other party if you encounter any problems.
