Opening, sharing, and managing OneDrive-stored documents directly within Teams
Hi Angus,
May I confirm if the issue only occurs when viewing the documents in the Browser version of Teams and OneDrive?
What will happen if using the Teams desktop client or open the file via OneDrive sync client?
Also, if it only happens in the browser, please suggest your end users to clear their browser cache and cookies, or using the Incognito session to open Teams or OneDrive. See if the same issue persist.
Meanwhile, if the suggestion above does not solve the issue, it would be appreciated if you can provide us a screenshot of the HTTP 404 page.
Appreciate for your understanding.
Regards,
Alex Chen
