TokenFactoryIFrame

Hello,

I am using outlook in a Safari browser on my Mac. Whenever I visit outlook "TokenFactoryIFrame" downloads every 5-10 seconds. I have not clicked on any of these as I do not know if it is malware or not.

Does anyone know what this is and how I can fix it?

* 2022-05-04: Seems this is still happening to a lot of people and there is no full solution yet.

Thank you

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

    I am an Exchange Online users as well with this issue. I have submitted via admin.microsoft.com both a report an issue and a support case. For an issue with this many users providing the same issue starting today. Why has this not been declared an incident and a notice sent out?

    I have recreated the issue several times. It only happens in Safari ADN it only happens with Outlook Web Access. I login to Office 365 and don't have the problem until I go to Outlook. If I go back to Office 365 the problem disappears. I have also tried Word, but it doesn't happen there. If I login directly to Outlook Web Access, it starts right away.

    In Safari, in the developers Console, I found several:

    failed to load resource: The server responded with a status of 400:

    https://webshell.suite.office.com/iframe/TokenFactoryIframe?origin=https%3A%2F%2Foutlook.office365.com&shsid=3b04f390-15af-4d4b-ba92-84376de13ce5&apiver=oneshell&cshver=20220405.3

    There are many of the failed to load resource messages, they vary slightly but then repeat. They all point to the same url, which very much looks to be a Microsoft URL. It drops a TokenFactoryIframe (Zero Bytes) into my Downloads folder. There is only 1 file. The repeated action, just overwrites the previous file.

    Where is this on the IPAD? I see solutions for the Mac, but I need a solution for the IPAD Air since I don’t know where to go on this device.
