Attention on use of Dropbox etc. on the Zengaku Computer System
Users can install and use online storage client software such as Dropbox. It is useful, but there are some points that you should be careful. Please use it at your own risk.
- Be careful for the capacity difference between the online storage and your home area of the Zengaku Computer System. When data on online storage are synchronized with your home area of the Zengaku Computer System, the usage may reach the upper limit without noticing it, and causes trouble such as losing your files.
- For the reason described above, we recommend that you do not use it synchronously on the Zengaku Computer System but only upload and download through a browser. If you want to synchronize, please set the online storage client software carefully so that there is no problem. Especially make sure of folders to be synchronized.
- ACCC will not deal with troubles related to online storage client software installed individually. Please use it at your own risk.
Warning: Do not use outlet in satellite computer rooms
There were smoke emission and ignition accidents of personal devices plugged into electrical outlets in satellite computer rooms. Except for permitted devices such as satellite terminals and projectors, do not use power taps and outlets in computer rooms.
Do not remove connected plugs without permission, because removing them causes to interfere with classes and maintenance works.
On Measure against Account Abuse
Recently, yet more news articles report damage caused by phishing or account hijack. In fact, also here in our university, we receive reports about such damage caused by account abuse. We’d like our users to be very careful about managing accounts.
As an emergency action against incidents such as supposedly abnormal transmission of mail messages, we may temporally lock user’s account without notifying the owner of the account. Under such circumstances, we will interview the user for more information.
We ask for your kind understanding and cooperation.
Usage restrictions due to temporary suspension of the core network
Due to maintenance on the core network system, network serviceswill be temporarily suspended during the following times.

How to resolve the problem when authenticating Microsoft Office products on a satellite device (Update 10/16)
A problem has been observed when launching Microsoft Office products on satellite terminals.
Please check the following links for solutions to the problems that have occurred.
- Office product does not start / A dialog box appears and “Error code 80090016” is displayed.
- When starting up the Office product, a screen appears asking for a multifactor authentication code number even though I do not remember setting up multifactor authentication, and I cannot proceed.
- Office product does not start / The screen goes blank at the authentication operation and does not proceed.
Office product does not start / A dialog box appears and “Error code 80090016” is displayed.
Solution
- Open [Start] – [Settings] – [Accounts] – [Access to work or school].
- Click [Disconnect] when the connected accounts are displayed.
- Two confirmation dialogs will appear in succession. Click [Yes] on the first dialog and [Disconnect] on the second dialog.
When asked to restart, do so. - After completing the above, start the Microsoft Office product again and enter your @u email address and password when the dialog box appears.
This trouble may also occur when you use a satellite device with an account that you signed in to without following the settings below when signing in at the time of Office product startup on your PC.
This procedure is different from the setting when using Office products on a satellite device. Please be careful.
The following is a reference to an image posted on the A.C.C.C. Web.

If the above does not resolve the issue, please try this as well.
When starting up Office products, a screen asking for a code number for multi-factor authentication appears even though I do not remember setting up multi-factor authentication, and you cannot proceed.
Solution
You can reset your authentication system on the following URL.
<https://portal.cc.tsukuba.ac.jp/member/microsoft365-reset-mfa/>
(When accessing this system, please log in using your Unified Authentication ID/PW).
As indicated on this page, you can reset the settings by clicking on the ‘Start to reset my MFA setting’ button.
The screen goes blank at the authentication operation and does not proceed.
When launching Microsoft Office applications on Windows Remote Desktop or Satellite Terminal of The Zengaku Computer System, the screen may go blank at the authentication process and you may not be able to proceed. In some cases, you may be asked to perform the same authentication operation several times.
Solution
You can improve the situation by disabling the multi-factor authentication setting at the following site.
Academic Computing Communications Center,University of Tsukuba
Cloud mail service authentication setting system (Microsoft 365)
https://m365setting.u.tsukuba.ac.jp/
Even if the authentication appears to be disabled on the screen, the authentication behavior may be improved by enabling it once and then disabling it again.
Alternatively, the error no longer occurs when the multi-factor authentication settings are completed to the end.
To reproduce the problem
The problem was reproduced when Office was started with the multi-factor authentication setting halfway completed.
If multi-factor authentication is enabled and the associated authentication application or phone settings are not completed, the authentication screen of the Office app version will go blank or an error message will appear.
Solution #3 added on 7/28
A new solution has been found and added to the FAQ. “Change account settings” in Windows.
Please see below for details.
