We’re seeing a problem with our Windows and Mac editions of Office where the “Versions” button is missing from the toolbar. We’re also not able to connect to Office 365 Sites from each app’s Document Gallery.
On Windows, we see the Sites option, but when we click it, it reads “This service is unavailable...” On Macs, Sites is not even listed. Only the user’s OneDrive, and SharePoint.
We’re trying to figure out why this is happening since those items were available when all machines were running the previous update.
