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.

PGB network switch upgrades on Monday, June 3, 2019 from 11am to 1pm

In order to be ready for VoIP, we will be upgrading the network switches in PGB on Monday, June 3, 2019 from 11am to 1pm.  Network connections will be temporarily unavailable while we do the upgrades.  If all goes smoothly we expect to have just two 10-15 minute outages to complete the transition.

Network switch upgrades on Wednesday, May 1 from 11am to 3pm

We will be upgrading the last four network edge switches for our main math network in Bahen on Wednesday, May 1st from 11am to 3pm.  The following offices will be affected:

BA6120 BA6191 BA6193 BA6200 BA6202 BA6204 BA6206 BA6208 BA6209
BA6211 BA6212 BA6214 BA6216 BA6218 BA6224 BA6226 BA6228 BA6230
BA6232 BA6234 BA6236 BA6242 BA6244 BA6246 BA6248 BA6250 BA6252
BA6256 BA6258 BA6260 BA6262 BA6264 BA6266 BA6268 BA6270 BA6283
BA6290 BA6290A BA6290A BA6290C BA6290G BA6290G BA6290J BA6291

The lw2 and lw3 printers will be affected by these outages, so they will be unavailable while their network connections are being upgraded.

The Computer Room (BA6200), as listed above, will also be affected.

Power outage at Bahen

At approximately 19:30 on Thursday April 4th there was an extensive power outage across campus which also affected the Bahen building. Power to Bahen returned at approximately 20:15, and efforts to restart the computer systems at the Mathematics Department commenced at 20:30. All systems were back online by 22:15.

Default resolution for Ricoh scanning is now 400dpi

Since the scanning done on the Ricoh photocopiers in BA6290A and PG104A is primarily for Crowdmark and the photocopiers had different resolution defaults we decided to make them the same.  It was suggested that 400 dpi would be good, so we have done that.  If you think that 300 dpi would be a better default please let us know.

There seems to be no way to change the default contrast setting and whether one wishes to have the scanning set to one- or two-sided on these photocopiers.

Short network outage for some rooms on Wednesday 2019mar20 from 4:15-5:00pm

On Wednesday March 20 during the server upgrade time from 4:15-5:00pm we will be testing one of the new switches that we will be installing for VoIP.  People in the following rooms will be affected:

BA6102  BA6103  BA6104  BA6106  BA6107  BA6108  BA6110  BA6112  BA6114  BA6116  BA6118

This will be a short test and we expect that computers in those offices will not be without network connections for more than 15 minutes.
