Support for M365 Apps (O365) on Windows 2022
- Sep 06, 2022
First off I would like to thank everyone for the feedback and apologize for the delay in responding to this thread. Your feedback has made a difference, and sparked many internal discussions... we have customers running M365 on WS2016 and WS2019 today, and we want to enable staying current and secure being able to upgrade to WS2022.
<UPDATED EDIT> In response to your feedback we have announced support for M365 on Windows Server 2022, please see this link for additional information:

Again, thank you for your feedback and passion!!

AJS10 allow me to correct.
"Then there is the issue that Windows Server is only on LTSC (or at least is via OnPremise), but used to be on LTSC & SAC."
Windows Server is available in Azure and on-premises via Azure Stack HCI hardware + OS, as a SAC like version called Windows Server Datacenter Azure Edition, which also brings some advanced features the LTSC does not offer (yet).
"Finally there are the rumours that Windows Server GUI mode will be deprecated"
Some parts are frozen zone, this is especially true for all legacy management tools.
Exception: DSAC has seen an important bugfix after 10 years in Windows Server 2022.
If you install Windows Server Insider, you will notice that it inherited the Windows 11 UI. There are many applications relying on the GUI features of Windows Server.
On the other hand, there are a lot of Windows Server installations using a GUI, where technically speaking it is not needed at all. The Core Installation mode has made great progress over time, even without installing the optional compatibility package.
In many cases admins and vendors I work with are still very hesitant to install Windows Server core variant, where possible, as they feel urged to be able to logon to an interactive local session to manage apps and things via RDP. It is a very strong muscle memory in most cases.
Then there are applications that really need the GUI mode, which won't run in the Core Installation Mode. Some applications even have binary dependencies to the GUI installation mode, thankfully they are on the way out.
I personally disagree that the GUI of Windows Server is going away. We have so many win32 apps which do not offer any remote management tools, remote management interface, or PowerShell support.
Every native .net or web app should run fine on WS Core.
The irony of this whole thread is that software vendors are pushing their applications into SaaS software models (as per O365/M365), which at least in theory means the need for RDS/VDI reduces as these become browser based. This is of course not a real world scenario as so many companies have legacy sunset / specialist software or secure use cases and they still need RDS/VDI to access it. Of course Microsoft may argue that Single User Windows 10/11 is now available to everyone at a lower cost point, especially with the recent CSP licensing changes - but this does not provide the flexibility and cost point for most customers that just want RDS (or its replacement).
From a commercial perspective the Evergreen Subscription model is great, but companies tend to work on fixed capital budgets with the option to reduce operational costs if things take a dive. Then they also have the option to sweat the asset for years afterwards. With Azure you are in reality required to take longer term 3yr reservations to get a similar cost point, but these would require renewing at end of term and are "officially" not cancellable. There are also the other issues whereby storage/disk/backup are not fixed pricing for the term and Microsoft has changing policies etc. Small to Medium businesses either embrace digital transformation, or want to stick to a traditional capex/opex model with certainty for the duration. ie they buy once and don't have to worry about it for 3-5 years.
I guess perhaps the question is (and perhaps the answer that we all need from Microsoft) is whether the RDS role is going to be deprecated in future Windows Server releases. Certainly, in Azure Virtual Desktop there is a push for users to run Multi Session Windows 10/11 rather than RDS (I also heard on the grapevine from a partner that Microsoft recently announced at a Partner conference that they will be deprecating RDS in AVD - but I have not validated this). The Microsoft answer to date is to use Azure or Azure HCI, which as you note also still includes the SAC release model - but I would expect most to see this lock-in as dangerously anti-competitive on the Cloud Provider and Hypervisor side of things.
You may sense I keep pushing for Windows Multi Session outside of Azure as it seems like a relatively simple approach to all of the challenges Microsoft and ourselves face.
Single Product set to Support, Zero Anti-Competitiveness concerns on the Windows, Cloud Provider and Hypervisor side of things, choice for users via Azure, On Premise or A.N.Other Cloud/Hypervisor, enables Microsoft to align the development of Windows and their support policies, and enables the onwards push towards GUI less Server etc etc.
