Office 365 comes with a subscription license for Microsoft Office Desktop Software

Users are able to download and install the latest version of Microsoft Office through the Office 365 portal on their personal and home computers or mobile devices such as tablets or smartphones. This desktop version of Microsoft Office is activated using a subscription license that is tied to your University of Guelph Office 365 account. This subscription license is provided to all users for no charge as long as they are affiliated with the university. Unfortunately, when you leave university and your account is locked or deleted, you will no longer be able to continue using this version of Microsoft Office and your ability to use the desktop software will be reduced. In order to continue using the desktop Microsoft Office software after you no longer have a valid subscription through the University, you will need to purchase a personal Office 365 subscription from Microsoft with a separate Microsoft account - not your U of G Gryphmail account. There are five downloads allowed per PC, Mac and mobile device. That's right! 15 downloads!


Before downloading O365, please check the following to avoid common installation issues.
