Download from sharepoint, exchange online, onedrive is blocked even if the Device is Compliant

You have created a Conditional Access (CA) Policy in which you have defined a session control for Conditional Access App control setting to blocks the downloads from Microsoft Online services e.g. Sharepoint, Teams, Exchange Online etc. In this policy, you have also excluded the Devices which are compliant by using a Device State condition.

But when users working from a compliant device, they are unable to download files. If there are additional MCAS policies in place which are targetted to non-compliant devices, those policies will also not be affected / work.

When you will check user’s sign-in logs on Microsoft Azure Portal, you will find that the Join type is blank and therefore device compliant calculation says Compliant: No.

Therefore, even if the device is compliant, it seems like the device compliance details are not passed to the Azure AD and MCAS policies and CA policies which target / statisfy the compliant device will be ineffective. This occurs when you access any cloud based application using an internet browser for example Google Chrome or Microsoft Edge.

Device compliant setting only works with the following supported browsers. Allowing the device to be identified and validated against a policy. The device check fails if the browser is running in private mode or if cookies are disabled. Google Chrome requires an Extention called Windows 10 accounts to be able to identify the Device if its compliant or not. For Microsoft Edge, you need to be logged in to edge browser to be able to identify the Device status.
