Hello
i agree if you expect more than 1000 items to be returned by the filter the trick will not work as you must go and check the rest of the results using pagination.
What's funny is that the Microsoft allowed usage of EQ in deviceManagement/importedwindowsAutopilotDeviceIdentities and from all i read EQ allow to escape space using %20
so question is why Microsoft allow it in one api and not another one ? which reason do that ?
and agree By design as it even don't work in their GUI of Intune
We have same issue at works and i tried to find a workaround for a colleague strungling the same issue as you
This is the only one working
Even tray to combine multiple contains in the filter using and but only the first one is taken (bug also i believe)
