Microsoft Teams - this workbook was opened from a server in read-only mode

Hello everyone!

I've on MS teams some excel files, I know that we can do a collaborate work with my teammates because I've already done before, but I don't know. Now, only one person can edit the workbook and when someone else try to open, it opened with the message "this workbook was opened from a server in read-only mode"

In both PC we syncrhonized oneDrive folder with the same files for work from MS teams, but I dont know what should I do to fix it.

I hope someone know the solution, thanks.

well the most important thing you need to know about Microsoft distributions like this is that they're completely unreliable and bug ridden every time they release a new version. Microsoft is notorious for this nonsense and they have been for 30 plus years. my recommendation would be to restart both machines empty anything you can out of Windows that's temporary junk and possibly reboot your server if you have access to it. That will certainly clear out any hidden used connections or concurrencies that you do not know about if that is indeed what the problem is. the other thing you should know is that OneDrive is completely unreliable too in my experience. I once installed OneDrive on a desktop machine and automatically without any warnings or any message boxes or anything files started saving to that area even when I would save them through a browser in a specific location other than that one it's completely ridiculous that's why I never work with Microsoft tools. Now there's nothing wrong with Microsoft I'm just stating my opinion on the company
