Microsoft keeps nudging Windows users toward the “new Outlook,” and plenty of people want to remove it. For what it’s worth, Microsoft’s own migration roadmap still lists new Outlook as “opt-in” and off by default – the automatic switch-over hasn’t officially kicked in yet – and classic Outlook isn’t going anywhere, with support confirmed until at least 2029.
Here’s how to remove or disable new Outlook right now, plus what to consider if you’re just tired of Microsoft changing the experience out from under you.
Why do people end up here
A few things tend to send people looking for the uninstall button: missing features they relied on in classic Outlook (rules, PST support, offline access), shared mailbox quirks, or just general frustration with Microsoft changing the experience without much say in the matter.
Option 1: Toggle back to classic Outlook
If new Outlook was installed alongside your existing classic Outlook, there’s usually a toggle switch in the top-right corner of the app labeled “Try the new Outlook” – switching it off reverts you to the classic version instantly.
Option 2: Uninstall the new Outlook app entirely
-
Open Windows Settings > Apps > Installed apps
-
Search for “new Outlook for Windows” (new Outlook appears as a separate app from classic Outlook or Microsoft 365)
-
Select it and choose Uninstall
-
Restart your computer to complete the removal
Option 3: Disable auto-install via policy (advanced/IT admins)
If you’re managing multiple devices, you can block new Outlook from being pushed to users at all through Microsoft 365 admin center policies. Microsoft’s admin docs lay out how: disable automatic migration entirely or just hide the “Try the new Outlook” toggle so it never shows up in the first place.
Option 4: Stop dealing with the back-and-forth entirely
If you’re removing new Outlook because you keep running into missing features, it’s worth considering a client that isn’t tied to Microsoft’s release cycle or its cloud-first redesign at all. eM Client connects to the same Outlook.com or Exchange account, but keeps full offline access, PST import, and a proper rules engine – without being subject to Microsoft’s ongoing rebuild.
FAQ
Will uninstalling new Outlook delete my emails?
No, your mailbox data lives on the server (or in classic Outlook’s data files), not inside the new Outlook app itself.
Can I permanently stop new Outlook from reinstalling?
Yes, through the toggle setting or admin policy, though Microsoft tweaks its rollout behavior now and then – worth double-checking your settings if it ever reappears.
What exactly is missing from new Outlook?
Microsoft has its own comparison table, but for a closer look at what features switching to eM Client can get you, see our comparison page here.
Is there an alternative that avoids these problems altogether?
Yes – eM Client connects to the same Outlook.com or Exchange account, with full offline access, PST support, and a complete rules engine already built in.
