SharePoint/Excel - This content presents a potential security issue. Do you trust this content?
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.
Thank you, Ben Johnson, for posting this simple solution! It was easy to implement for the users affected at my organization.
