The ability to only allow specific machines to access corporate email via outlook e.g. corporate windows clients
Since migrating to EO plan1 we have allowed access to corporate email.
We are regulated so security is very important.
In this respect (due to the type of content shared by email) we have restricted any devices accessing EAS via non-company devices. We have also blocked OWA. Next, we need tto stop non-corporate devices from accessing email through outlook.
I've been told intune could have dont this but it cannot..
