Another Windows 11 update problem has surfaced, this time taking down two of Microsoft’s most-used communication apps. Microsoft now has a workaround for the Teams and New Outlook crashing issue — here’s what users need to know.
Issue status: Microsoft has published a workaround for the crashing apps issue on Windows 11.
- Status: Workaround available (exact steps not fully detailed in the initial report)
- Affected builds: Not yet specified by Microsoft
- Affected apps: Microsoft Teams and New Outlook for Windows
- Platform: Windows 11
What’s happening with Teams and New Outlook crashing?
According to the report from Neowin, a subset of Windows 11 users have found that both Microsoft Teams and New Outlook for Windows crash shortly after launching. That’s a genuinely frustrating problem for anyone who relies on these apps for daily work communication, since it effectively removes two of the primary ways people chat, join meetings, and read email in a single morning.
The issue is being described as tied to a recent Windows 11 update, though Microsoft hasn’t pinned down exactly which build is responsible in the details shared so far. What’s clear is that this isn’t a one-off glitch affecting a handful of machines — it’s hitting a specific group of devices, which points to a compatibility problem between the updated operating system and these two apps.
One thing worth flagging up front: the initial report doesn’t include specific build numbers, a KB article ID, or the exact workaround steps. Until Microsoft publishes those details, treat anything more specific than “a workaround exists” as unconfirmed.
Which Windows 11 devices are affected?
Microsoft has characterized the problem as affecting “a specific group of devices,” but hasn’t released the full list of affected builds or the exact criteria that determine which machines are impacted. In practice, that kind of phrasing usually means the crash is linked to a particular combination of Windows 11 version, hardware configuration, or app build — rather than every Windows 11 PC out there.
If you’re wondering whether your machine is in the affected group, the honest answer is that Microsoft hasn’t published a checklist yet. The best approach is to watch for an official update from Microsoft that either resolves the issue or clarifies which builds are affected, rather than assuming your device is or isn’t involved.
What is the workaround?
Microsoft has confirmed it has a workaround ready for users running into the crash. The initial report confirms the fix exists but doesn’t spell out the exact steps, so the precise procedure should be confirmed via Microsoft’s official support channels rather than third-party guesswork.
For context on what such a workaround typically involves: app-crash issues on Windows 11 are often resolved by clearing the app’s cached data, repairing or reinstalling the app, disabling a conflicting startup entry, or rolling back to a previous app version. But rather than guess at which of these Microsoft intends, users should rely on the official guidance once it’s published in full.
Background: New Outlook and Teams on Windows 11
To understand the impact, it helps to know what these two apps actually are. New Outlook for Windows — sometimes labeled “Outlook for the web” or simply the “new Outlook” — is Microsoft’s newer, browser-based take on the classic Outlook desktop client. Microsoft has been gradually pushing users away from the traditional Outlook client toward this newer version, which it markets as faster and more web-like.
Microsoft Teams, meanwhile, is the collaboration hub where most Windows businesses run their chat, video meetings, and file sharing. A crash in either app cuts people off from core work tools, which is why this issue draws attention even though it only affects a subset of devices.
This also fits a broader pattern: as Microsoft consolidates its productivity apps and pushes cloud-based versions, temporary compatibility hiccups between the OS and these apps tend to surface after major Windows updates. That’s not an excuse for the disruption, but it explains why such crashes show up periodically.
What this means for you
For everyday Windows 11 users, the practical takeaway is simple: if Teams or New Outlook keeps closing on you, you’re not alone and you’re not the only one Microsoft is aware of. The company has acknowledged the problem and has a workaround, so the situation is being actively managed rather than left to users to figure out on their own.
The catch is timing. Since the exact workaround steps and affected builds haven’t been fully disclosed in the initial report, you may need to wait for Microsoft to publish the detailed fix. In the meantime, restarting the apps and checking for app updates won’t hurt — but don’t go reinstalling Windows or rolling back your OS based on unverified advice.
How to get the fix
The most reliable path is to check Microsoft’s official support pages and the Windows Insider Blog for the published workaround and any affected-build details. Microsoft should post the exact steps there, and that’s the authoritative source to follow rather than random forum posts.
Keep both Teams and New Outlook updated to their latest versions, and if the crashes persist, report the issue through the built-in feedback tools in each app. That feedback helps Microsoft track how widespread the problem is and prioritizes a proper fix.
Once Microsoft releases the full workaround steps, applying them should resolve the crashes for affected devices. Until then, patience and official channels are your best bet.
