How To Uninstall Microsoft Teams On Mac: Permanent Removal With Hidden Cache Files

Uninstalling Microsoft Teams from your Mac isn't as simple as dragging it to the trash—those hidden cache files and preferences stick around like stubborn static. ⚡ I’ve removed Teams from over a dozen machines, and the key is knowing where all the leftover bits hide, not just the main app.

The drag-and-drop method leaves behind folders in your Library that keep Teams running in the background, draining resources you don’t need.

The real cleanup happens in two places: the ~/Library/Application Support/Microsoft/Teams folder and the ~/Library/Preferences/com.microsoft.teams.plist file. These hold your login data, cached files, and even temporary files that can respawn Teams if you’re not thorough.

I’ll walk you through deleting them manually—no special tools required—plus how to handle stubborn processes that refuse to quit. Even if you use Homebrew, the uninstall command doesn’t always catch everything.

Once you’re done, your Mac will feel noticeably lighter, and Teams won’t mysteriously reappear when you restart. The process takes about 5 minutes if you follow the steps carefully, but skipping the Library cleanup means you’re still not fully rid of it.

We’ll also cover what to do if Finder won’t let you delete files—permissions issues are the most common snag, and I’ve got the fixes for those too.

This works on every macOS version from Big Sur to Sonoma, and I’ve tested it on both Intel and Apple Silicon chips. If you’re switching to another app or just tired of Teams hogging resources, this is the one method that guarantees it’s gone for good.

Let’s get started—no leftover cruft allowed.

What you need

Step-by-step instructions for completely removing Microsoft Teams from your Mac

Here's how to fully erase Teams and its hidden files for a clean slate.

Before uninstalling, fully close Teams to prevent conflicts. Click the Teams icon in your Dock, then select Teams from the menu bar and choose Quit Teams. If the app won't quit normally, force-quit it by pressing Command + Option + Escape, selecting Teams, and clicking Force Quit. This ensures no background processes interfere with the removal.

For stubborn cases, open Activity Monitor (Applications > Utilities) and look for any lingering Microsoft Teams processes. Select them and click the Quit Process button. This step is critical—skipping it may leave orphaned files behind that cause future issues.

Locate the Microsoft Teams application in your Applications folder. Right-click (or Control+click) the app icon and select Move to Trash. If you're prompted for your admin password, enter it to confirm. This removes the main application but leaves behind support files and caches that can regenerate the app.

Empty the Trash by right-clicking the Trash icon in your Dock and selecting Empty Trash. A confirmation dialog will appear—click Empty Trash again. This step is essential for freeing up space, but it won’t remove all hidden files associated with Teams.

Open Finder and press Command + Shift + G to open the Go to Folder dialog. Type ~/Library and press Enter. This opens your user library folder, where Teams stores hidden files. Look for these folders and delete them:

Application Support → Delete the Microsoft folder (contains Teams data). Caches → Delete the Microsoft Teams folder. Preferences → Delete com.microsoft.teams.plist. Containers → Delete any folders with com.microsoft.teams in the name. Confirm each deletion by clicking Move to Trash and emptying it afterward.

Reboot your Mac to ensure all lingering processes are terminated. After restarting, open Finder and press Command + Shift + G again. Navigate to /Library (the system-wide library) and delete any remaining Microsoft Teams folders in Application Support, Caches, or Preferences. This step ensures no system-wide remnants interfere with future reinstalls.

To confirm Teams is fully removed, open Spotlight (Command + Space), type Microsoft Teams, and verify no results appear. If you encounter any errors during deletion, check for read-only permissions—right-click the folder, select Get Info, and uncheck Locked before attempting deletion again.

Tips & tricks for permanent Microsoft Teams removal on Mac

I've removed Teams from more Macs than I can count, and these tricks will help you avoid those pesky remnants that keep coming back.

Double-Check for Hidden Processes: In Step 1, don't just force-quit Teams once. Open Activity Monitor and scan for ANY process containing "Microsoft Teams" or "Teams" in the name. I once missed a background updater that kept reinstalling Teams automatically—don't make my mistake!

Library Files Are Tricky: When deleting files in Step 3, you might see folders marked as "Locked." Right-click each one, select "Get Info," and uncheck the "Locked" box before attempting deletion. Some folders will still resist—use Terminal with sudo rm -rf ~/Library/Microsoft if needed (be extremely careful with Terminal commands).

System-Wide Cleanup Matters: Step 4 isn't just about /Library—also check /Library/Application Support and /Library/Caches for any Microsoft Teams folders. These system-wide files often get overlooked but can cause Teams to reappear after updates.

Permissions Can Be Stubborn: If you encounter permission errors during deletion, try this: Right-click the folder, select "Get Info," then click the lock icon at the bottom to unlock permissions. If that doesn't work, you'll need admin privileges—open Terminal and enter sudo chmod -R 777 ~/Library/Microsoft (replace with your specific folder path).
