If you rely on Microsoft Teams, here’s a MASSIVE heads up on something… if you don’t keep it updated, it’s going to stop working altogether 😬

Microsoft recently announced that Teams desktop apps which haven’t been updated in 90 days or longer will be blocked from use.

Let that sink in.

This isn’t just a friendly nudge to install an update. It’s a hard stop.

If the app is out of date…

🔔 You’ll see a warning banner at the 60-day mark (30 days if you’re on a virtual desktop).

🚫 Once you hit 90 days, the app will stop working until it’s updated.

🗓️ And this has already rolled out for everyone.

Why is Microsoft doing this?

🔒 Security, plain and simple.

Today, even small delays in patching can leave doors open to attackers. Microsoft’s stance is clear: If you want to use Teams, you need to keep it secure.

To be fair, Teams is designed to update automatically. And in most businesses, it does. But not all systems are managed the same way.

⚠️ If your company has devices that don’t get regular updates…

⚠️ Or if you’re using Teams in a virtual desktop environment…

You might run into this issue.

Here’s what I recommend:

✅ Make sure Teams auto-updates are enabled across all devices.

✅ Run a quick audit to check for out-of-date clients.

✅ Let your staff know what the warning banners mean. And what to do if they see one.

✅ Have a plan in place for manual updates if needed.

The last thing you want is your people locked out of Teams during a busy week because of an update that slipped through the cracks.

Need help checking your Teams update policy or making sure everything’s covered? That’s the kind of thing my team and I help businesses with – before it becomes a fire to put out 🔥
