Since this morning several client versions of excel that have a pointing to sharepoint (our tenant) give the following message; does this happen to anyone else?

micheleariis, we started having the same problem today. This fixed it for me: Control Panel > Internet Options > Security Tab > Trusted Sites > Click Sites > Enter https://mycompanyname.sharepoint.com with mycompanyname being whatever your sharepoint subdomain is. Mine had mycompanyname-files.shaepoint.com and mycompanyname-myfiles.sharepoint.com but not the normal one. That fixed it for me.

I expect a correction from Microsoft 🙂

Hi, from word I haven't had any reports yet; before taking corrective action I would like to see if Microsoft will fix it automatically.

Yup. The same exact thing began happening to my users this morning as well. Users who work on Excel spreadsheets from SharePoint online get this error every time they open. Was not an issue yesterday 7-30-24. Became an issue this morning.

    Even our users still have problems.
    I hope for a resolution from Microsoft; I wouldn't want to go handing out policies and exceptions on devices.
