I discovered today that users (including myself) have suddenly lost the ability to overwrite documents from the Document Library web part. It just gives the following error:

Sorry, there was a problem uploading this file. Please try again.

problem uploading this file

I can upload a new file without issue or alternatively I can click "See All" to go directly to the full document library and overwrite without issue there.

But for some reason, I can no longer overwrite documents from the web part.

Why would this be?

  • Maybe it's because some documents are open by somebody? Commented Apr 27, 2021 at 21:50
  • @DenisMolodtsov - This is happening with every document in the library. Commented Apr 27, 2021 at 22:03
  • What about other users in your org? Have you tried in another browser?

  • @Allen_MSFT - It's happening in all browsers and as far as I can tell, all users too - including myself (SharePoint admin). Commented Apr 28, 2021 at 13:35

I ended up creating a ticket with Microsoft on the issue and per the 2 agents I spoke with, this is a new bug that many customers are reporting. They are currently working on a fix with no ETA.
