A Microsoft file hosting and synchronization service.
Based on your description, the Authorize button should normally open a pop-up window or authorization dialog that allows you to grant permission for the OneDrive Migration Tool to access the required Canvas APIs. If clicking Authorize does nothing, the most likely causes are browser settings (such as blocked pop-ups or cookies) or an issue with the Canvas/Microsoft 365 tool configuration and permissions.
Please try the following steps first:
- Open Canvas in Microsoft Edge or Chrome using a normal browser window.
- Allow pop-ups and cookies, including third-party cookies, for your Canvas site and Microsoft OneDrive. Microsoft specifically requires cookies and pop-ups to be enabled for the OneDrive LTI authorization process.
- Temporarily disable browser extensions such as pop-up blockers or privacy tools.
- Sign out of both Canvas and Microsoft 365, restart the browser, and then sign in again using your school Microsoft 365 account.
- Try the Authorize button again.
If the issue persists, I recommend contacting your school's Canvas/Microsoft 365 administrator, as this is typically the fastest and most effective way to get assistance when using a school account. They can verify that Microsoft 365 admin consent has been granted, confirm that the Microsoft 365 LTI app is correctly configured in Canvas, and review any permissions or settings that may be preventing the authorization process from completing.
I hope these suggestions give you some helpful troubleshooting steps to try and point you to the right place for further support if needed.
Thank you for taking time.
