Bob, sorry for a few questions:
- Are you using the web version of Teams or the installed version? If the web version, perhaps re-start the browser or try a different one?
- Are you clicking on an Office document (Word, Excel), and if yes, did that document open before, and if not is it an older version of Office (e.g., doc) or a non-Office document?
- Network or computer issues? Perhaps try the 'turn it off and on again' option?
- Anything else to help us identify what the problem might be?

Yes, the file will open if I open in SharePoint or if I hit "open in excel online". It only get the error inside of Teams.

It occurs in both the web version and desktop application. Yes I am clicking on the document form the files tab... I also have files set as "tabs" in the channel and they do the same thing from there. If I click on a file in a conversation... same result. And yes sir, I did try completely signing out of everything Microsoft and restarting the computer. Same result. :(

It's not for every user. It has actually only happened to two users. It happened last week and lasted for about a day for one user.... then it started working again. It happened to me also for about a day then started working again. But now it is happening again to me. It's crazy.

I agree with Chris, check with other users and if it's widespread, log a ticket. We are having no issues (in Sydney, Australia) with this.

Yes, both machines are behind a corporate firewall, but ALL of the machines are behind the same firewall with the same settings. Its just really weird to me that it works for awhile (like a week or so) then it the error shows up again for a day or so.

Experienced this today with myself and another user. Adding here to help others.
I happened to close Teams at lunch and didn't reopen until 5pm. Works now.
Seems like some sort of login cache issue.
I didn't sign out on my phone, but wasn't using teams.
I was also signed into Office all day.
Hope this helps someone else.

I have the same issue. For several days I just used the web version as a workaround. Restarted several times but that didn't fix the issue. Finally, I went into Task Manager and removed all tasks related to MS Teams. That finally resolved it for me.
Hope this helps someone.

I am having this same issue. We're using the free version of Teams. The issue has affected everyone. The files aren't on the sharepoint or on OneDrive. I get the same result on the web app and the desktop app.
I get the "unknown error" when trying to access an xlsx file that we turned into a channel tab. We also get the message "the specified list in invalid" when accessing the "Files" tab in every channel.
Any help will be greatly appreciated.
(@Matt_Anderton adding you here as I noticed you had/have the same problem)

@rpkin Hi Ryan, I have a few questions about this. First, when you say you are using the 'free' version of MS Teams, what actually does that mean? Do you have a corporate licence for Microsoft 365 and if so, what licence type (e.g., E3, E1 etc)? If you don't have a corporate licence, then you won't be able to access SharePoint which also means OneDrive.
But I'm wondering what you are actually doing. I'm happy to help out but need a bit more basic info first, starting with your licence type. It is possible your users are 'front line workers'? Thanks

I'm using the free version of Teams. This is a screen shot from the Microsoft website:
So you can see in the image that it lists file storage. We were using this file storage and it appears to be gone now.
