*Important Update Fall 2022*

Microsoft Transition to Modern Authentication for Increased Security.

After October 1, 2022, your access to e-mail or other services may be impacted.
Read Below to determine if you will be impacted and start preparing now to avoid any disruptions.

If you are actively enrolled in Duo, this issue has already been addressed for you.

After October 1, 2022, all clients and apps that use Office 365 Basic Authentication will be affected and unable to connect.

Microsoft will be fully moving to utilize Modern Authentication for Office 365 services and will disable support for Basic Authentication.

This change will primarily impact access to Microsoft Office 365 email that are using apps that do not use Modern Authentication. Read below for other impacts.

What do I need to do to Prepare for this Change?

Users are strongly encouraged to use the Outlook app, which is easily configurable on Windows, macOS, iOS, and Android.

To ensure the best level of support for our users, UIT will offer end-user support for email using the Outlook client. This is because our email system is Microsoft and Microsoft only supports the use of the Outlook App.

You may continue to use other email clients, e.g. native email clients on phones, Mac mail etc., but these will not be supported by UIT.

Apple Note* If you are currently using a supported version of native email client, after the sunset of Basic Authentication, you may need to delete your account (from the mail app) and re-add it to see if it will work.

UIT will provide guidance on adding your account, but if this does not work UIT will not be able to troubleshoot these issues.

What are the impacts of this change?

This change will primarily impact access to Microsoft Office 365 email that are using apps that do not use Modern Authentication. This affects older mail clients that use IMAP, POP3 (such as Thunderbird), and ActiveSync connections (such as Android Mail and older versions of iOS Mail) as well as Outlook 2010 or older. 

Any other apps that connect to other services may be impacted too.

The Gmail “Send As” feature will no longer function. This feature does not use Modern Authentication. Google has, to date, not implemented support the Modern Authentication Protocol (OAuth2) for this feature. 

Other authentication methods that may also be impacted include Exchange Web Services (EWS), Exchange ActiveSync (EAS), POP, IMAP, Remote PowerShell, MAPI, RPC, SMTP AUTH, and OAB.

More information

Modern Authentication and Basic Authentication are terms for connection methods between a client (for example, your laptop or your phone) and the Office 365 servers. Currently, MSU’s Office 365 environment allows users to authenticate with Office 365 services using both Basic Authentication as well as Modern Authentication. This will be going away on October 1, 2022.
