Hi @Ray_handels,

Up to now, I have seen this issue taking place with both instant clones (Horizon) but also non-horizon VM's. With UEM, but also without UEM.

With regards to your last question. It may depend on which files are locked at that moment. That may be files that the user, that doesn't have the issue at that moment, doesn't have permissions for. Maybe that's the case?

Something I also tested (at the request of UEMdev​) is using a Windows Server 2019 or Windows 10 (v1809) file share and disable leasing for that share (Set-SMBShare -LeasingMode None). This also results in the issues NOT taking place anymore. Not the solution for everyone, but just to provide another option for some.
