BigSur with Sophos Endpoint - OneDrive for Business files don't download

Hi, When trying to download a file in OneDrive whether using Files on-demand in the OneDrive client or not they don't.
The issue occurs whether it is the onedrive of the user or a SharePoint library.

With files on-demand enabled, all the placeholder files and folders come down fine but if you double click to open the OneDrive download box comes up but progress bar and downloaded size doesn't go up. After about a minute it times out with error code 16.

With files on-demand turned off no files download and OneDrive sits ttrying to sync processing changes but don't download.

No detections or events are shown in the client or Sophos Central.

I have gone through Admin Login in the Sophos client and disabled all options but it is still the same.

If i uninstall Sophos Endpoint then OneDrive works as normal.

Any help to get to the bottom of this would be massively appreciated.

Thanks
Mike

  • So, i have narrowed this down to the Threat Protection Device policy and the 3 options under Real-time Scanning - Internet. If any of the the 3 options are enabled then OneDrive stops downloading.
    The 3 options are "Scan downloads in progress", "Block access to malicious websites" and Detect low-reputaion files".

    Presumably this is down to the service(s) that these options enable on the client end and seemingly aren't disabled when doing the admin login and disabling all options (as i did to test initially).

    With one of these options enabled it shows in the Services section of the Self help tool 3 services "Sophos SXL", "Sophos Web Intelligence" and "SophosWebNetworkExtension". These aren't present with all the Real-time Scanning options off.
    They are also all showing green so presumably should be working.

    It is worth noting that everything else seems fine, i can access the web in Chrome and Safari and even my onedrive via the web accessing the same files i'm testing synced in the client.

    My test machine is a fresh install of Big Sur, not an upgrade.

    Thank you for reporting this. 

    I will direct this to the development team to look at further. 

    Can we get an SDU from the machine and a tcpdump during sync where it succeeds and one where it doesn't.
