UTOS Emergency Maintenance

18:00 July 21 to July 24, 2023, any access from outside

[Performed on 7/19] Maintenance to remove alumni accounts that cannot use MS Teams from the team

This maintenance was performed on Wednesday, July 19, 2023.
Due to some errors, some users could not be removed from the team.
This will be addressed in the future.


From the end of last academical year (this March), graduates can use their  @u.tsukuba.ac.jp mail address even after graduation.

However, because they are no longer the licensees of other Microsoft (MS) products such as MS Teams, confusions may rise like the following.

  • In a Team which the graduated member belongs to, other members can send he/she messages.
  • The graduated member who can no longer access MS Teams , cannot read the message, neither know that he/she has been sent a message.

To avoid such unnecessary confusions, graduate accounts will be removed from any teams by the system administrator on July 18 or 19, 2023.

It may take some time before the removed accounts disappear from the teams.

Remarks : Please be assured that in the teams, chat logs and/or files uploaded/created by the removed users will not be deleted.

Changing Default Values for Sharing in SharePoint and OneDrive

We have changed the default selection for the SharePoint and OneDrive sharing range when you “Copy Link” in Microsoft 365 from “All users (anyone who knows the link can edit it)” to “Users with existing access rights”.

Please refer to the screenshots below and change the selection according to the scope you wish to share.

*The default value when “copying a link” has been changed, and the default value when sharing a file on a chat between individuals in Teams may also change as a result.
In addition, the default values for other Microsoft 365 applications and functions may also change in the future, so please be careful when changing the public range settings when sharing files again.

*Please note that changing the default values will not change the accessibility of items that have already been shared.

(SharePoint)
SharePointーdefault
(★ Clicking on “Users with existing access rights use the link >” will allow you to select the scope of other sharing.)

(OneDrive)

(★ Clicking on “Users with existing access rights use the link >” will allow you to select the scope of other sharing.)
