Multi-factor Authentication (MFA) in e-mail applications

E-mail and calendar apps that come with MacOS 10.14 (Mojave) and later work normally. However, depending on your Mac settings, you may need to delete and re-add your e-mail and/or calendar account in order for the service to work.

In these instructions, the previous account will be deleted and re-added. This is method is, at this time, the surest way to make multifactor authentication work.

Deleting an account

First, we'll delete the previous account. If you don't already have an account, you can skip this step and go directly to the next step.

• Open System Preferences > Internet Accounts (@ icon)
• In the list on the left, select the account you want to delete. The account may be named Exchange or you may have named it, e.g. “UH”. In any case, you will see an E logo on the account.
• Then, press the minus button at the end of the list on the left. 

• You'll still be asked to confirm if you're sure you want to delete the account. This confirmation shows your username in a long format: username@ad.helsinki.fi (e.g. rkeskiva@ad.helsinki.fi or hy12345@ad.helsinki.fi). Click OK. 

You have now successfully deleted the account and we can re-add the account to enable multifactor authentication.

Adding an account

• Ensure you are in the Internet Accounts view (System Preferences > Internet Accounts  (@ icon)).
• In the list on the right, select Exchange. 

• Ensure your name is correct in the Name  section and, in Email Address, enter the long form of your username: username@ad.helsinki.fi (e.g. rkeskiva@ad.helsinki.fi or hy12345@ad.helsinki.fi). 
• After entering the data, click Sign In. 

• Next, you'll get a confirmation that your login details will be sent to Microsoft for signing in. Select Sign In. 

• You will then be presented with the university's login window, where you will need to enter your password and select Sign in. 

• After logging in with your username and password, you will be redirected to the Multifactor Authentication you have selected. Once authenticated, you can choose which programs you want to use with the account you have added. Here, we recommend ticking at least Mail and Calendars. 
• When you press Done, your account is added and you can start using it. Then, open the programs you want to use your account with.

E-mail and calendar apps work normally. However, depending on your device settings, you may need to delete and re-add your e-mail and/or calendar account in order for the service to work.
