TokenFactoryIFrame

Hi All,

Service Health Dashboard has indicated that issue EX375556 has been resolved as of: End time: Thursday, May 5, 2022, at 7:32 PM UTC.

User Impact: Users were repeatedly prompted to download "TokenFactoryIframe" when browsing Outlook on the web via Safari on Mac OS.

Final status: Our fix addressing the impacting property mismatch has successfully completed deployment. We've confirmed via service telemetry and through additional reports from some formerly affected users that impact is remediated for all users.

Scope of impact: This issue affected all users leveraging the Safari browser to access Outlook on the web.

Root cause: A recent update to our Office User Experience (UX) changed a parameter from “conditional” to “required” in order to sync client-side and service-side properties. However, the Outlook on the web service didn’t receive the same change as intended, resulting in a property mismatch and repeated "TokenFactoryIFrame" download prompts.

If you are still experiencing an issue, please let us know by starting a new thread as this may indicate either a scoping issue or an independent problem.

Best regards,

Shyamal
