OK how do I just STOP NEW OUTLOOK alltogether?

[thecomputerguy]

Getting calls all about this.

People using Outlook (Classic) are now getting double notifications of mail because New Outlook has installed itself and configured itself automatically with the users credentials on top of Outlook Classic

- I open up New Outlook, delete the account, the problem goes away.
Two days later, the account is reconfigured again in New Outlook automatically
- I delete the account and uninstall New Outlook
Two days later, New Outlook is reinstalled and reconfigured automatically.

I followed the steps in this article: https://learn.microsoft.com/en-us/microsoft-365-apps/outlook/get-started/control-install

Which allowed me to turn off the toggle to Try the New Oulook, then uninstall the new outlook, then add this registry key:

reg add HKCU\Software\Policies\Microsoft\office\16.0\outlook\preferences /v NewOutlookMigrationUserSetting /t REG_DWORD /d 0x00000000

Is that it?

I seem to remember someone, maybe @callthatgirl, mentioning that at some point there will be no old Outlook. So this may be the kick off to that game?

That's the GP I used in a few places in the past that had on prem servers.
For all 365 clients it can managed via InTune also
Although I stopped doing that in the past...over 6 months, since the new Outlook has gotten a bit better. Still more cooking to do in the oven, but it's not a huge pain anymore, and I figure, as we settle end users in with it now, in short time when Microsoft forces the cutover..we'll be that much more ahead.

New Outlook and Outlook Classic are, underneath it all, one and the same thing as far as your email goes, why you would be getting double email messages I have absolutely no idea. I can still toggle between Outlook Classic and New Outlook in the Outlook Classic and New Outlook interfaces, but of course, that's for me (and most of my clients) who are using M365 Personal or Family. There should be no ability (under normal circumstances) for New Outlook and Outlook Classic to be running simultaneously.

I do know that Outlook Classic will be in support until 2029 and have read several different articles (including the one you reference) on how to keep New Outlook from being switched over to in an organization until the IT department (you, in this case) want for that to occur (or that it must occur at sunset for Outlook Classic).

I wish people here would stay on topic and answer questions without the need to teach and not answer the question.

Here is what I am doing:
If you manage their 365, you can disable it with GP update

If you don't manage it, you can do the registry fix and that might work, might not. A windows update could break that later.

I'm telling clients to toggle back to classic and I'm not doing reg hacks for any clients. Some of my clients are seeing classic disappear and then I have to download it again or find the launcher and setup new profiles. Huge pain the ass.

I know for Business...you also can run both simultaneously. Not saying one should, I don't go tell clients that, but...I can run both at the same time, and as I've shown clients the subtle differences...I'll run both at the same time on their computers also to show them the differences.

I just launched both again on my computer..same exact data shows up, no "duplication". I don't see how it could duplicate things.

Duplicate as in duplicate notifications like New Outlook and Classic Outlook are running at the same time. Classic Outlook in the foreground and New Outlook running invisibly in the background

I would guess...tell them they don't have to launch both versions of Outlook.
I always have my standard that I set each users desktop to.
I put their frequent flyer program shortcuts on the task bar.
Word, Excel, Outlook, Teams....and optionally some others.
I manage that. If they're on Outlook classic, they have the shortcut for that. If I have switched them to new...I remove the Outlook classic shortcut and give them a shortcut for the new one. Although I believe the system knows if you're migrated to New...and even if you leave the classic shortcut there, it will still launch the new. I don't see a way for users to have "both" open unless they intentionally launch both.

I also always modify the "defaults" also..so that mail or ICS files will default to..whichever program.

couldnt you turn off notifications for new Outlook?

I could but I have a feeling it will be re-enabled in an update in the future ... like MS does with all the edge crap all the time.

I remember the Office ribbon controversy very well. Seem to remember that it was optional in '07. Meaning you could revert to the old File, Edit, etc drop down menus. I believe by '13 there only was the ribbon. When "they" decide to "re-arrange the furniture" on us our opinions don't really matter.

 

[britechguy]

As do I, but I have no recall of any option to keep using the menu driven system versus the then-new ribbon interface.

People hate change, and I was among those people, but nothing is so constant as change, and nowhere is change more frequent than in computing. I barely remember menus anymore even though I used them for a period of time that's still much longer than the ribbon interface.

I pin classic outlook to the taskbar, lol works for me.

Why windows 10 to force users to 11 to avoid this turd of a "new" Outlook?

Yup, easily managed via InTune

But is the toggle the issue here? My understanding is that Outlook itself, during the Opt-Out phase of release (which we're in now), will be auto-switching to the New Outlook UI unless the measures specified by MS to prevent it are taken. (Sorry, I focused on the checkbox that was shown as checked in your screenshot, not the other two, which are the ones that matter).

The complaints I'm seeing so far are of the, "This changed with out my asking," and/or, "When I installed Outlook I got this weird New Outlook, not Outlook Classic," type.

My understanding is that all new Outlook installs will default to the New Outlook UI (barring specific action to short-circuit the default).

BTW, I am so ready to kill MS for the inanity of "New Outlook for Windows" as the common terminology for New Outlook (over 365) while still using Outlook for Windows as the terminology for the free mail, calendar, and people apps replacement which has the identical UI at this time. Talk about making every possible mistake as far as sowing confusion about what's what!

 

[YeOldeStonecat]

I have not seen Outlook automatically take over/replace classic Outlook, and Microsofts news states "It does not replace existing (classic) Outlook or change any configurations / user defaults."

I've only see it suggest...gently...that the end user slide that button to try it. Present end users with a button, and they'll hit it. Despite them later saying that they never did...after they call you for help to solve something not working properly in the "new Outlook".

So...I remove the temptation of that slide button to "try it".



I have not seen "when" the New Outlook will start taking over by default...so far we've only read that it is automatically being installed. And it "can" run along side classic Outlook (which I've seen for quite a while now).


When the "New" Outlook starts taking over from duties that have been assigned to "Classic" Outlook, is when we'll start to have a lot more end user calls/tickets.


I know from experience, many end users, and sadly..."techs"...never go into the "default app settings"...and lock these down to one, or the other.
Here is a rather "default" setting for Outlook..."out of the box".
Notice... EML, MSG, WEBCAL, etc...either blank, or some even default to Windows features (like People). I always..always...change each and every one of these...to Outlook....for every client of mine. Which I firmly believe results in a lot less calls from clients, and less frustration for me..and I see other techs frequently complain about "new" outlook taking these over. I firmly believe it's because they never set these to begin with, or at least manage these with GPs or InTune.




This is more like what is should be like (and you only see about 1/3 of the scrolling screen here..but each and every line should be filled in with Outlook...unless you want the "new" one.

From page: https://learn.microsoft.com/en-us/microsoft-365-apps/outlook/get-started/deployment-new-outlook

• Both Outlook (classic) and Outlook (new) appear in the Start menu and are available for use based on an organization's policy settings.

I can definitely say that this is the case for me, even as a home/family M365 user. And I just made my first successful attempt to be running both, simultaneously. For the longest time, you could only have one Outlook instance up, and it was either New Outlook or Outlook Classic. Now you can have side-by-side instances of both.

What's kinda amusing is that in Outlook Classic that "Try the new Outlook" toggle still shows even when New Outlook is already up and runnning before you fire up Outlook Classic.

In any business environment I'd definitely prefer to have that toggle not be displayed and where the end user would make the choice of which UI they wanted to use based on their choice in the start menu (or shortcuts on the desktop or quick launch that they set up).
