How can I participate as a guest on Teams for job searching, joint research, etc.?

If you want to participate on Teams as a guest for a job search or joint research, the procedure is as follows.

  1. If there is a participation URL, access it and participate
  2. 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.

    Even someone’s account is permanently deleted, the posted files to “Team” are still stored on the SharePoint site and the members can access that data.
    You can also browse previous posts by being invited by the relevant team again on your new account.
    Files posted to “Team” will be stored on the SharePoint site associated with the team, and the items will be shared with team members.
