Actual impact to ActiveSync clients when enabling Hybrid Modern Authentication
Last point I want to add is that my pre-existing and new setups via the Gmail app, i.e. basic auth, continue to work without issue, post-enabling HMA.
bbolling2342 I'm glad it helped, and also nice to have another person present in my thread, so I'm not just on an island by myself bantering:).
Since this other topic is fresh for me, a similar and commonly unknown/unsure topic in this realm is the one that was announced here: Upcoming Exchange Online Device Access and Conditional Access changes with Outlook mobile
It's not related to this thread, to confirm. I just am sharing to point out that you can target specific users with Conditional Access policies in order to allow them to use the Outlook app, requiring either or both the device to be managed/compliant and an Intune App Protection policy to be applied, all while NOT targeting other users, and still have those other users be unallowed to use the Outlook app, by relying on Device Access Rules in EXO. The users who are targeted by the CA policies will simply bypass the EXO Device Access Rules. This is a big deal for customers who have historically disallowed the Outlook mobile app but are now trying to make the switch. That process is now a walk in the park.
The big parallel between these two topics is that the Exchange Team has managed to enable customers to granularly roll out some pretty big changes, WITHOUT impacting existing clients/devices. Both topics are fairly lengthy and a little convoluted, so it's easy to miss the great deal that they did accomplish for customers. For this, praise to the The_Exchange_Team .
