Office 365 Files- unable to open from all browsers

Occasional Visitor

I am using a Mac (OSX 10.13.4) and over the past 24 hours, I have noticed that I can no longer open any files that are saved through Office 365 (for business) in a browser--meaning that they won't open in the Office 365 online environment but they will open in the standalone app, if I chose to do so.

 

I have found that in Chrome, it is identifying them as "not secure" and I can open them, however, the issue is that the other users of these shared files are also encountering this and I am getting e-maIls about this constantly. I have no idea what happened and have tried to problem solve this on my own but am at a loss here. Can anyone help?

I would suggest you open a support case and work with the engineers to resolve this.
