Other common problems:

• You may not be licensed for Office 365 - active faculty, staff, and students are eligible. If you are part of one of these groups, and there is no Install option on the Office 365 page, please contact the Technology Services Help Desk.

Repeated prompts to Activate or Login when using netid@illinois.edu:

• The most common fix is to check that Time/Date are set automatically and ensure that the person is logged into the software.
• The second most common issue is that a netid@illinois.edu address has been used for a personal, or consumer, Microsoft Office 365 account.

To check for this issue, login on the OneDrive.com site using your netid@illinois.edu address. If you are redirected to the campus Office 365 password page, but are still getting repeated login prompts, contact the Technology Services Help Desk. If you get a message that indicates your email address has been used for more than one account, or asks you to select your work/school account or personal account, you will need to log into your personal Microsoft Office 365 account and change the associated email address to one that is not netid@illinois.edu.
