Outlook Mail

[driftwood]

Any way to prevent windows from auto installing outlook mail?

[king1]

I'd start with, which flavour of Outlook are we talking about?

The good old Outlook desktop app, part of Office
The new Outlook for Windows, windows mail replacement
The Outlook web app (not likely )


Assuming the new Outlook App, this uninstalled it for me...
https://techcommunity.microsoft.com/t5/o...-p/3941499

Code:

Remove-AppxProvisionedPackage -AllUsers -Online -PackageName (Get-AppxPackage Microsoft.OutlookForWindows).PackageFullName 

and if you want to block it installing again this link suggests a couple of registry keys that trigger the install
https://www.reddit.com/r/Windows11/comme...k_and_dev/

Code:

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\WindowsUpdate\Orchestrator\UScheduler\DevHomeUpdate]
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\WindowsUpdate\Orchestrator\UScheduler\OutlookUpdate]

AND/OR

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\WindowsUpdate\Orchestrator\UScheduler_Oobe\DevHomeUpdate]
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\WindowsUpdate\Orchestrator\UScheduler_Oobe\OutlookUpdate]

Usual warnings, backup first etc...

It's the one that takes over my windows mail app.
I usually just uninstall it from programs, but it keeps reinstalling.
So I'm thinking it's the one you are calling "the new outlook for windows, windows mail replacement"

yes that sounds right 

Looks like this on mine, and download is here
https://apps.microsoft.com/detail/9nrx63...n-us&gl=US


so by the sounds of it the way to block it installing again is by deleting the registry keys from the reddit link above, if your comfortable doing so.  I would do the top one first and see if that does the job first (Ignore the DevHome keys I originally posted, they are unrelated.)

But a final word, this feels like the kind of change that MS are always going to keep enabling - so you may block it for a while, but it may get re-enabled at the next feature update, as happens with various other windows settings, because MS in their infinite wisdom think they know better what end users need than the end users...

Thanks, I'll give that a try and see how it goes.

[driftwood]

Well that didn't work.
The UScheduler directory only had 2 files, IA & Medic.
There was no OutLookUpdate

I should have said this is on Windows 11 HP

Not to sure if this will work or not, depends in Microsoft all the New Mail app an "update"  What you can do is download the wushowhide.diagcab

Can download directly from  HERE    Suggest you did what you did before to remove the mail, then run the wushowhide.diagcab  See if it picks up the email install, then select it and block. Works wonders on computers that have problems with other updates.

You can also change the default app for your mail.

[driftwood]

wushowhide didn't find anything.

My default mail is the windows mail app.
Outlook just takes over when it's installed.
Easy enough to get rid of.
I just uninstall it from programs.
It gets reinstalled when there is any kind of update.
I have tried it and will use it if I have to, but prefer the other.
