Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
Try signing in directly to Microsoft 365 instead of using the invitation or download link.
- Open a browser and go to
https://www.office.com. - Select Sign in.
- Sign in with the Microsoft 365 work or school account that has the assigned license.
- If sign-in succeeds, look for Install apps in the upper-right corner.
- Select Install apps > Microsoft 365 apps.
If the same redirect loop appears, test these browser checks in order:
- Open an InPrivate window and try again.
- Try a different browser.
- Clear cached images/files and cookies, then retry.
- In Edge, go to
edge://extensionsand temporarily turn off extensions one by one to check whether one is interfering. - Try a new Edge profile:
- Select the profile icon in the upper-left corner of Edge.
- Select Add profile > Add.
- Retry the sign-in and download in that new profile.
- If downloads start but then fail, check the download folder in
edge://settings/downloadsand verify the folder exists, is writable, and the disk is not full.
If the issue happens only from the email link but not from https://www.office.com, the problem is likely the invitation link path rather than the Microsoft 365 app installation itself.
If the issue occurs across multiple browsers, InPrivate, another device, and direct sign-in at https://www.office.com, the problem is likely with the account sign-in flow rather than the local browser session.
