We can open the file on the desktop and save back to the cloud but we need to collaborate online.

Hi Eric, 

Welcome to the Box Community!

Have you tried using different browsers and try to open the file via office online again? Do you get the same error message?

Upon doing some research, this looks like an issue on compatibility on Microsoft side, see this article I found online: https://answers.microsoft.com/en-us/msoffice/forum/msoffice_sharepoint-mso_win10-mso_o365b/sharepoint-excel-compatibility-issues-with/efe04ae0-b63f-4016-b939-524dcde93ed0
