Latest Message<\/th>\nTitle: Users may be unable to leverage the Immersive Reader feature in some Microsoft 365 services<\/p>\n

User impact: Users may have been unable to leverage the Immersive Reader feature in some Microsoft 365 services.<\/p>\n

More info: Impact may have been seen in the following services:<\/p>\n

– Outlook on the web
– Microsoft Forms
– Microsoft Teams desktop and mobile apps
– Reading Coach
– EDU Assignments
– Word Online
– PowerPoint Online
– Excel Online
– Office Lens<\/p>\n

Final status: After monitoring our service health telemetry for an extended period, we\u2019ve determined that the previously mentioned fix was effective in resolving the issue, but was delayed in taking effect. Our telemetry has confirmed that the fix has now restored the Immersive Reader feature for the affected users as expected and impact is remediated.<\/p>\n

Scope of impact: This issue could have potentially affected any user that attempted 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

End time: Thursday, July 17, 2025, at 6:16 PM UTC<\/p>\n

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cause: An update to authentication components coincided with an Immersive Reader feature update, which resulted in an outdated authentication call and subsequently caused the service to deny authentication requests for the Immersive Reader feature.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

Next steps:
– We\u2019re reviewing our update procedures pertaining to the authentication components responsible for facilitating access to the Immersive Reader feature to prevent similar impact in future updates.<\/p>\n

This is the final update for the event.<\/td>\n<\/tr>\n
