Outlook <-> Exchange Protocols
During Ignite I saw a presentation that suggested Outlook was moving to a new communication protocol "Hx" from the current REST API method (Mobile) and MAPI/HTTP (Desktop)
I was surprised to hear that migration was going to begin at the end of this year.
Does anyone know where to find more information about this new protocol? Like what builds of Outlook are needed, how to tell when you are using it etc. Some of the benefits like improved sync are appealing (assuming it works).

So apparently that's the protocol the win mobile app used, and will now be used by all non-desktop apps. Transition should happen by end of year, it's transparent to the end users. One of the benefits is that it eliminates the additional proxy service currently running in Azure.
Some additional details here: https://youtu.be/dt5GomXuqhI?t=325
It would be nice to have some technical details of the new protocol - similar to what we saw when we transitioned from RPC -> MAPI. Especially since they say we'll all be transitioned by year end! There are all kinds of network appliances that may need to be tweaked for the new protocols.
Well, it just appeared on the Roadmap... with tons of additional information :)

I would like to have more Infos to that too. Anyoune found a link to that Protocol?
Unfortunately I've not gotten anywhere finding out any additional information about this via my usual channels. I had hoped there were some PG members looking at this community but apparently not.
As a side-note, I did find this documentation on Exchange/Outlook protocols which is absolutely awesome - although nothing about Hx.
The transition from RPC to MAPI wasn't well documented either, but there were some good articles available for people who did want to dive into the details.
Just saw some additional info around this in BRK 2177: https://youtu.be/jEbjTOfezLU?t=1370
Probed the PG about it, will report back with any info they share.
- Good find. Although the presenter left out Outlook for PC/Desktop in the versions of Outlook that are moving to Hx. I left the session I was in with the impression it was coming to all versions of Outlook.
Hopefully you get some meaningful info to share from your PG contacts.
Has anyone found more info on the Hx protocol?
I'm still catching up on all the stuff I missed, which session did you see that announced at?
I haven't had a chance to watch the other Outlook sessions either, but the one I was in at the event was:
