Strange behavior when using Sharepoint WebDAV

[MSCom]

Hello,

we are using Explorer View to access files on a SharePoint Online site. More specific a Teams SharePoint site. We are accessing the site via the Path

\\[email protected]\DavWWWRoot\sites\Group-Name\Shared Documents

and map it as a network drive. This works all fine, until this morning where we had the following issue:

- we save a file to the mapped network drive connected via WebDAV (it does not matter if we do this manually by creating a file, or saving via third-party apps)

- when opening the folder in Windows Explorer, no files were visible

- when opening the site-path in Sharpoint Online and Teams, the files are visible

- when opening the path without "DavWWWRoot" in Explorer and even mapping to it, the files are also visible.


So my question is:

What might be the cause for not beeing able to see the files via the WebDAV-path, but when accessing the same path from all other options, even through Windows Explorer but with removed "DavWWWRoot"?


Regards and thanks in advance

Sebastian
