My company is still experiencing this issue, so I opened a ticket with Microsoft support. They responded with the following notice:

SP867513- Some users incorrectly receive a security warning prompt when opening Excel or PowerPoint files in SharePoint Online

Title: Some users incorrectly receive a security warning prompt when opening Excel or PowerPoint files in SharePoint Online

More info: More specifically, users may incorrectly receive a security prompt when opening Word, Excel or PowerPoint files in their respective web apps within SharePoint Online. Also, affected users may see the following message "This content presents a potential issue".
While we're working to remediate impact, we recommend that users update their Microsoft 365 Office clients by accessing an application and selecting the following options:
File > Account > Microsoft 365 and Office Updates > Update Options > Update Now
Current status: The fix deployment is progressing slower than anticipated and we're looking into methods to expedite this process. We've also identified that this warning prompt is displaying when known safe links are selected and are investigating ways to streamline this process and prevent extraneous alerts going forward.

Updating the Office client did not fix the issue unfortunately.

Also interesting is that the issue ID provided isn't visible in the Health Center: https://admin.microsoft.com/#/servicehealth/history/:/alerts/SP867513 (if I try the link, I get a permission-related error).

My organization is still facing this issue as of August 21st.

After updating to latest update, still facing same issue...

As of 8/21/24 it pops up when I use Word.

Hi All,

Is there any update on this? For us, the issue persists.

Thank you
