Like the title says, some of my users are suddenly experiencing a weird issue with opening Excel files that are stored on On Prem SP 2016. Normally, these users would click on the file in SP2016 and the file would auto-load into Excel, with a yellow bar “Check Out Required….” message that would appear below the ribbon in Excel, along with the Check out button.
All of a sudden, a couple of our users no longer receive the yellow bar Check Out Required message after loading the file in Excel. Additionally, if the user goes to the File menu in Excel, there’s no Check Out button there either. The users experiencing the issue are a mix of Full Control level users and Contributor level users. Users can still select the file in SP and check the file out via the SP ribbon, but even after doing that, the file opens in read only in Excel with no way to edit it. I’ve also verified that no updates were pushed to their PCs.
Has anyone ever encountered this behavior before and successfully fixed it? Resetting IE settings and running a repair on Office 2013 didn’t do the trick either.
