Current status: Our monitoring systems identified an issue where users may be unable to leverage the Immersive Reader feature in some Microsoft 365 services. Our investigation has determined that an update to authentication components coincided with an Immersive Reader feature update, which is resulting in an outdated authentication call and subsequently causing the service to deny authentication requests. We’re correcting the feature update to utilize the updated authentication method to resolve the issue.<\/p>\n

Scope of impact: This issue can potentially affect any user that’s attempting to leverage the Immersive Reader feature in the services outlined in the More info section of this communication.<\/p>\n

Start time: Thursday, July 17, 2025, at 3:00 AM UTC<\/p>\n

Root cause: An update to authentication components coincided with an Immersive Reader feature update, which is resulting in an outdated authentication call and subsequently causing the service to deny authentication requests for the Immersive Reader feature.<\/p>\n
