If you need further assistance, please contact the WTS Helpdesk.

Why am I getting an "Access is not allowed because you are not enrolled in Duo" error when I log into myoffice.uwo.ca?

This error indicates you haven't setup any devices with Duo Mobile, Western's Multi-Factor Authentication service. Visit https://mfa.uwo.ca for instructions on setting up MFA for your account.

Which Operating Systems are supported for Office installations?

Windows OS: Windows 11, Windows 10, or Windows 8.1.

macOS: The three most recent versions of macOS. When a new version of macOS is released, the macOS requirement becomes one of the then-current three most recent versions: the new version of macOS and the previous two versions.

How do I check which devices I've installed Office onto?

If you've already signed into MyOffice.uwo.ca, you can view provide a list of your active Office installations under the Devices dropdown at https://portal.office.com/account/?ref=MeControl#

To navigate to this page manually:

  • Sign into https://MyOffice.uwo.ca
  • Select your profile picture in the top right corner -> View Account
  • Select Office Apps from the left navigation
  • Under the Office section, expand the Devices dropdown

Why can't I access the personal Microsoft 365 account I subscribed to prior to 2015?
If you had a previous personal Microsoft 365 account that uses your Western credentials, you now have an option to choose either account:

  • Go to https://office.microsoft.com (instead of using the “microsoftonline” link)
  • In the top right of that page there is a “Sign In” drop down with two options, “For Home” and “Work, School or University.
  • Select the “For Home” option then log in using your personal Microsoft credentials

This will take you to your personal O365 account where you can manage office software, onedrive, use office online, and so on.

Why is it asking for an activation key when I install Office on my Mac computer?
The software is activated by signing into Office365 with your Western Credentials. On install, you should be given three options for activation; choose the second option:
      (1) Activation code - enter a product key
      (2) Sign into an existing office 365 subscription
      (3) Try office 365, including office for Mac

Can I use Office365 when I'm offline?
You don’t need to be connected to the Internet all the time to use Office desktop programs like Word and Excel, but you must connect to the Internet at least once every 30 days. This is so that the status of your subscriptions can be checked. If you don’t connect within 30 days, Office goes into reduced functionality mode. After you connect to the Internet and your subscription status is verified, all the features of Office are available again.

If I leave Western how long will MS Office continue to be available and what happens to the software?
The timeframe for deactivation of the software benefit will vary, depending on the nature of your relationship to Western.

  • Once deactivated, the software will go into a state of reduced functionality
  • In order to continue to use Microsoft Office after this point, you will need to purchase a full copy of the software or arrange for a personal subscription to Microsoft Office 365
