Blocking Microsoft Outlook and keeping Mail on Windows 10 IoT LTSC.
Posted by RomanianBagVoid@reddit | sysadmin | View on Reddit | 28 comments
Hi everyone, I have a PC to maintain where I have to keep the old Calendar and Mail.
I've tried a(1) variety(2) of fixes(3) to this issue in the Registry Editor.
Now I am at the point where when I open Microsoft Mail, Outlook auto-installs itself and Mail tells me to move to Outlook. The client, very obviously, doesn't want Outlook, because that breaks the Windows 10 machine and mandates Windows 11.
Other installed apps are: Photos (from W11) and Snip & Sketch (from W11). Office 2021 LTSC is as well installed but without Outlook.
Any suggestions on to how to block Outlook from auto-installing and maybe even hide the "try the new Outlook" buttons is welcome.

Why do you need the old apps? Maybe we can solve your problem with a bit more info.

Agenda view integration and mail notifications. Also, Outlook comes with ads built-in.

Thunderbird good one works with oauth 2.0 and has an excelent schedule app.

Yup, sounds like the vlassic XY problem with a nive solution once you go back one step.

I think it's time to move on. Why in the name of Countess Lovelace would you want to stay on Mail?

...why change something that ain't broken?
countsachot@reddit
Windows mail was broken out of the box.
RomanianBagVoid@reddit (OP)
How? I never had an issue with it.
countsachot@reddit
Completely lacking in features compared to outlook, Thunderbird, etc.

It was functionally equivalent to a mobile client, which is all I really needed. I don't need all the extra crap. I just use the web now. If I'm gonna be forced to use the web, I ain't using a web wrapper.

Nope. And trying won't work. Per MS, they won't let it connect to their servers anymore.

I didn’t know a single person used the “Mail” app
I’d really invite them to embrace outlook I don’t see how it “breaks” Win 10 LTSC

I’m starting to think you’re not exactly a sysadmin and that this is your personal computer
Fatel28@reddit
I have never once seen an ad in outlook wtf
sublimeinator@reddit
There are no ads for tenant based EXO accounts.

I'm lost here. So you mail but not outlook, you want windows 10 but not 11. Why and why.
St0nywall@reddit
The Mail and Calendar apps are actively blocked from use and will automatically upgrade. There is no way around this unfortuntely.
You need to use the new Outlook it gets replaced with or find an alternate mail application like Thunderbird.

I'm still hoping there's still some registry hack out there.
St0nywall@reddit
Sorry there are none.
EduRJBR@reddit
Why?
lolinyerface@reddit
Why is it ever this question? 90% it’s some Csuite that doesn’t want things to change and will make it your problem that a trillion dollar company is making changes to apps/tools.
EduRJBR@reddit
Yeah, I know...

New Outlook is the latest version of Mail, which being a Windows Store app will always keep itself updated.
How does New Outlook "mandate" Windows 11?

Agenda view integration and mail notifications. Also, Outlook comes with ads built-in.
Windows 11 does not have agenda view yet, the new Outlook has ads, and mail notifications barely work.
felix1429@reddit
What about Classic Outlook? No ads on that.
ExceptionEX@reddit
While it's wild and a loosing battle to try and maintain this position, not to mention insecure.
You can attempt to uninstall the new outlook in the app store, the reinstall it, but pause the process in the app store, then close app store.
This can generally hang things up.
But at some point MS is going to just block access to their servers via the mail app.
