O365 question

@obsolesce Is this something that requires Exchange 2016 to be running on-prem? It doesn't say in that article.

Almost nothing requires Exchange on prem any more. There are edge cases, but the majority will never need it for any of the functionality to exist. The other thing to consider is the replication direction. Most of the Exchange attributes do not need to be sync'd to AD, and will only exist in Exchange Online, thus bypassing AADconnect.

No, all you need to do is run a simple command that extends your AD Schema with the Exchange 2016 extensions / attributes. This is posted in the first step here. This is safe to do. All it does is adds the
ms-Exchattributes you see when you are in the properties of an AD object and look in the attributes tab. These are the attributes that AADConnect synchronizes to O365. There's no need for any on-prem exchange server. -

I know loads of shops that do this, and none have on prem Exchange of any sort. Hybrid deployments have been seen as very bad since going to hosted first happened. So much to break.

Go back and read the link I posted to MS supportI am just saying, currently, it is the supported method to have an Exchange server on-prem to manage mailboxes IF you want to use aadconnect.
Also, they hinted at a new service that would do away with the Exchange on-prem requirement at Ignite last year and the year before.

Where it says this:
In addition, even if you have directory synchronization in place without running the Hybrid Configuration Wizard, you still cannot manage most of the recipient tasks from the cloud.
That is by design... and is what you want! Because, you would then be "managing most of the recipient tasks" from on-prem AD instead... which synchronizes to the cloud.
When you use AADConnect and synchronize users/mailboxes from on-prem AD to O365, it's easier because you don't have to dick around in the O365 Admin portal... you do everything from within your AD users console! It's so much easier and faster.
A hybrid configuration is not at all the recommended set-up, in fact, it's the least recommended setup. Fully hosted on O365 is best, fully hosted on-prem Exchange is second, Hybrid is last (because it increases the complexity AND costs of everything).

@obsolesce To me, what you say makes sense. I still don't know why MS wouldn't promote that method and have it laid out saying that you should keep your Exchange server after a migration. So much so, that they have a special license that you can get for a hybrid management scenario.

That there is a license makes sense, their goal is to sell you more stuff.
But I've never heard MS recommend this, except for one or two rogue O365 people who took it upon themselves (and is why I don't trust MS for support.) But in general, I've always seen MS promoting eliminating on site Exchange just as much as the community.

@scottalanmiller - It is a free license, so selling more stuff doesn't really matter.

How do you get Exchange for free? I know that there are licenses that include it, but they cost more AFAIK.

Exchange has never been for free.

Also Hybrid Deployments I have only used it for customers that do not care for Exchange onsite to receive emails on mailboxes that are not in the cloud when the Internet is down. Hybrid Configurations a times need to be reconfigured (Meaning just running the wizard to confirm it is still in place)>
