I am trying to set up some Conditional Access policies that will allow non-compliant devices to access Office365 services in-browser, while also being able to use the Office suite on their device -- with the exception of adding a corporate email account to Outlook/Teams/OneDrive. Compliant devices should be able to use either browser or desktop apps, as well as adding their corporate email account to Outlook/Teams/OneDrive.
I attempted setting a policy that includes Office365 Exchange Online, and excludes Office365 but it appears Office365 contains Office365 Exchange Online and is taking precedence in the policy.
Is it possible to achieve the above scenario with basic Conditional Access policies?
The end goal is to prevent non-compliant devices from storing their mailbox data locally.
Thanks
