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.
bjohnson630 and all
Your fix in the Internet Options > Trusted Sites > add site of https://companyname.sharepoint.com worked for me too! Thank you!
