Legacy (basic) authentication, a less secure sign in method that can be used to access any email account, will be disabled by Microsoft in October 2022. Following this change, multi-factor authentication (MFA) will be required to sign in to all email accounts, which will help improve the security of your mailboxes and prevent unauthorized access. 

To address this change and ensure the Concordia community is well prepared, Instructional and Information Technology Services (IITS) will be progressively disabling legacy (basic) authentication on all faculty and staff email accounts in different phases over the coming months. 

What is legacy (basic) authentication? 

Legacy (basic) authentication is an email sign in procedure that allows users to sign in to their email accounts using a single user name and password, without multi-factor authentication (MFA).  This leaves accounts vulnerable to unauthorized access and information breaches due to limited protection. 

By turning off legacy (basic) authentication, MFA will be required at sign-in, providing greater security to your accounts and information. 

Why is legacy (basic) authentication being disabled? 

Concordia’s drive to disable legacy (basic) authentication is being undertaken to:

  • Ensure your information is secure from rapidly increasing cyber-attacks targeting Concordia.
  • To make sure the Concordia community is not impacted when Microsoft ends support for legacy (basic) authentication on October 1, 2022. 
  • To comply with governmental cyber security regulations. 

What you need to do

For colleagues currently using legacy (basic) authentication

To prevent any barriers from accessing your email account after Microsoft deactivates legacy (basic) authentication, users are required to have a modern email client that supports MFA.

No action is required until you receive detailed instructions from our dedicated support team. An IT representative will be reaching out over the coming weeks/months to assist you with configuring and/or upgrading to one of the following modern email clients that support MFA:

For detailed instructions on how to check if your email client is using legacy (basic) authentication, please check the FAQ section below. If you are using an email client other than the ones listed above, we strongly suggest installing Outlook on Windows and MacOS, or using OWA on Linux.

For colleagues not currently using legacy (basic) authentication

In the coming weeks, legacy/basic authentication will be gradually disabled for users that have not signed in to their email accounts using legacy/basic authentication for the past 30 to 60 days. No action is required, and this change should have no impact on your account.

How to upgrade or configure your email

It’s important to note that users should not upgrade or configure their email accounts until they have received detailed instructions to do so from IT services, doing so may require you to repeat the process at a later date. 

For configuration and/or upgrading details please select from the following options: 


Mobile devices: 

It’s important to note that once legacy protocols are disabled, you might need to reconfigure your email on your phone or tablet . 

Resources and support

During the upgrading and/or configuration process, a dedicated support team will be available via zoom to assist you remotely on the scheduled date legacy (basic) authentication is disabled on your account. 

For any questions or concerns, please contact the IT Service Desk by email at or call 514-848-2424, ext. 7613 between 8:00 a.m. and 11:00 p.m. on weekdays and between 9:00 a.m. and 4:30 p.m. on weekends. The legacy project support team will be working closely with the IT service desk to prioritize your calls. 



In your Outlook menu, go to "File" then "Office account". The version of your Outlook/Office suite is indicated in the Product Information section (see below). 


Please note: If you are using any other client than Microsoft Outlook, you are using a legacy protocol and will be required to update your account to Microsoft Outlook. Modern Authentication is used by default in Outlook.


On Apple/MacOS computers: Open your Outlook menu, choose "About Outlook", the version should be 16 or higher.
