Deprecation of Microsoft Basic Authentication

ICT can unfortunately offer little to no assistance in getting unsupported email clients working.

If you wish to continue to receive College emails using third-party providers, you could try the following general advice:

• Check whether your email offers "native Exchange" support (very few clients that don't come from Microsoft will do this).
• If it doesn't offer native support, then it is almost certainly using the IMAP protocol to access the Office 365 Exchange server. You will need to check whether the client supports IMAP authentication via "OAuth2", the industry-standard protocol for authorization. If it doesn't, then it's time to start planning a move to an email client which will continue working, such as Microsoft Outlook. Follow the Instructions on our website to setup Outlook for your device.

Most mobile device built-in email apps typically support modern authentication and are compatible with Outlook.

If you are in the minority where Outlook does not work, you can verify that your device is running the latest version of its email app. If the email app is at its current version, sign out and back into your account.

If you are notified that you are still using basic authentication after you have done the above, you might need to remove the account from the device and then add it back.

Some non-browser applications do not support modern authentication processes such as MFA. If you are having difficulty accessing your College emails on one of these apps, you may be able to set up an app password, which will still allow you to securely access your email. 

Visit our app passwords webpage, which lists the most used apps and outlines how you can setup an app password. If the app type or version you have isn’t listed there, please check the vendor’s website to see if your app is supported by modern authentication.

This email client is not supported by ICT, but our general advice is:

If are using Mac Mail and you aren't prompted to re-enter your password or can't see any of your email, you'll need to remove and then re-add your account from Apple Mail on your computer to enable modern authentication.

How to remove your email from Apple Mail

1. Open the Mail app on your computer.
2. Go to Mail in the upper-left corner.
3. Select Settings.
4. Select Accounts.
5. Select an account.
6. Click Remove.

How to add your account

1. Go to Mail.
2. Select Add Account
3. Select Microsoft Exchange
4. Enter your account information.
5. If you're asked about your account type, you'll need to choose Work or school, not Personal, to continue.

After successfully removing and re-adding your email account, it should automatically start using modern authentication.
