How to Enable Microsoft Planner Notifications in Teams on a Phone and Laptop
With this, you can stop worrying about whether Teams is actually keeping you updated.
Normally, when a new Plan is created in Microsoft Teams, notifications are turned on by default if you're part of that Plan from the start. So, if you're working remotely or your team uses Teams to manage tasks, there's a good chance you're already set up to get alerts the moment something drops. But default doesn’t always mean it’s working. Maybe you joined the Plan later. Maybe your desktop notifications are off. Or maybe your phone just isn’t syncing properly with the rest of Teams. That’s when you stop getting those "you’ve been assigned a task" nudges—and that’s when things start slipping through. To fix that. Here’s how to make sure your Planner notifications are turned on both on your phone and your PC.
Steps to Enable Planner Notifications on Phone (Microsoft Teams Mobile App)
Step 1. Open the Microsoft Teams app on your phone.

Step 2. Tap your profile icon in the top-left corner.

Step 3. Select "Notifications."

Step 4. Tap on “All activities.”

This will allow Teams to send push notifications for just about everything: chats, mentions, task assignments, etc. It’s what keeps you in the loop when tasks change or get dropped on your tab.
However, your mobile app relies on your desktop Teams settings for a lot of this. If Planner notifications aren’t properly set up on your PC, your phone might not pick them up either. So you’ll want to make sure that side’s handled too.
Steps to Enable Planner Notifications on PC (Microsoft Teams Desktop)
Step 1. Open Microsoft Teams on your PC.

Step 2. Click the three dots beside your profile icon in the top-right corner.

Step 3. Select “Settings.”

Step 4. Go to the “Notifications and activity” section.

Step 5. Scroll down until you find “Planner” or “Tasks by Planner and To Do” (depending on your org's setup).

Step 6. If yours is off, click on the toggle button beside "Planner" to turn it on.

Conclusion
Planner in Teams works best when everything’s connected: your desktop, mobile, and all the background settings in between. If your PC notifications aren’t synced properly, your phone won’t catch a thing. And that’s where the workflow starts to fall apart.
You could be out and about thinking everything’s in order, meanwhile, a task’s been assigned with the deadline’s creeping up, and your superior’s nudging you with a “hey, did you see the task?” message.
To avoid situations like this, it’s worth taking a few minutes to get your Planner notifications set up right on both devices. After that, Teams handles the rest.
