The following page has a comprehensive guide as to how to continue your classes online:

A few notes regarding meetings via MS Teams:

  1. If you type in an email address and it does not show up in a drop-down (i.e. it’s underlined in red) you can still leave it on the list of emails and it will accept it and send an email to that recipient.
  2. If you have a list of emails in a text file, one email per line, you can copy and paste the whole thing into the Attendees field of an Outlook meeting. This also works if you have the emails in an Excel column, one email per line.
  3. Perhaps the simplest thing is to create the meeting and just invite yourself. You can then share the link which is emailed to you with whomever you want. For example, if you have a course web page you can just schedule all the classes, invite yourself to each, and then just post the list of links on the web page indicating when they should be clicked on e.g. “Class for Monday March 24, 10am: https://path.of.url”.

UofT Data Classification and Health-Related Research/Administration

In an effort to try to help prevent the exposure of sensitive data the University is moving on several fronts, including defining a new data classification policy:

which will help people determine how sensitive their data is. There is a Draft FAQ at the bottom of that webpage which may answer some of your questions.

It is likely that access for research and/or administration to any personal health records as defined by PHIPA, the Personal Health Information Protection Act:

will require some form of MFA (multi-factor authentication), likely a two-factor authentication, and the University has started the MFA application assessment. This will apply to any such data that is accessed or stored on departmental or faculty-owned systems.

If you do any research and/or administration that needs access to personal health records please let us know at so that we will try to let you know more details when the new MFA policy is put into effect.  Of course this IT Status site is a good resource for finding out about updates and you should check back here if this affects you.

UTMail+ and spam filtering problems — important emails being deleted

If you use a “” or “” email address then please be aware that UofT moved all email to Microsoft and that changed the way that anti-spam works for those accounts; incoming mail is now scanned by Exchange Online Protection (EOP).

There have been sporadic reports of EOP generating spam false positives (legitimate messages marked as spam and delivered to the “Junk Email” folder instead of “Inbox” folder) .

Please check your “Junk Email” folder regularly to see if this has happened to you.  Email in the “Junk Email” is permanently deleted (with no possibility of being restored) after a deletion period.  That period was 30 days but due to this problem they have temporarily extended that period to 90 days.

Instructions for minimizing the impact of the email move are supposedly available on however no direct link was given.

People receiving email on our departmental mail server at addresses “” and “” are not affected by the UofT email change.

Move to VoIP close to completion

This morning we moved another 51 Bell Centrex lines to VoIP.  There are still a few lines in the department that need to be moved but it may take some time before that will be scheduled by the central people.

Please see the Departmental VoIP Information Page for more information.

215 Huron network switch upgrade

We will be testing a replacement network switch for VoIP for 215 Huron on Wednesday June 5 from 3:30pm-4:00pm.  Users in 215 Huron may experience short wired network outages during that time.  If all goes well then on Thursday June 6 from 3-4:30pm we plan to move everyone to the new switch.

The UofT wireless network will not be affected by our switch upgrade.
