Microsoft Edge: Allow M365 authentication popups in work profiles

Summary

When users are signed in with a work account, some Microsoft 365 sites (for example, microsoft.com, cloud.microsoft, and microsoft365.com) may open authentication pop-up windows to Microsoft sign-in endpoints such as login.microsoftonline.com, login.live.com, or login.microsoft.com. These pop-ups are required to complete sign-in. Microsoft Edge now allows authentication pop-up windows from Microsoft first party services by default. Admins can control availability to this feature using the M365AuthPopupsInWorkEnabled policy.
