How to Uninstall Outlook on Mac: No-Reset Clean Removal in 5 Minutes

Uninstalling Outlook on your Mac doesn’t have to leave behind stubborn files or hidden preferences. ⚡ I’ve removed it from dozens of machines—including my own—using the same method every time, and it takes less than five minutes when you follow the right steps.

The key is knowing where Outlook hides its traces beyond just the Applications folder.

Before you start, quit Outlook completely and back up any important emails or contacts—Microsoft’s uninstaller won’t recover deleted data. You’ll need admin permissions, so if you’re on a shared Mac, ask the owner first.

Most users stop here, but the real cleanup happens in Terminal where Outlook’s leftover files lurk in hidden folders. Trust me, skipping this step means your next install will feel sluggish.

You’ll end up with a completely clean system—no orphaned preference files, no lingering cache folders, and no mysterious crashes when you reinstall. The process is straightforward once you know the hidden spots Outlook leaves behind, and I’ll walk you through each one with exact commands.

Even if you’ve tried uninstalling before and still had issues, this method works every time.

For stubborn cases, we’ll cover alternative methods like using Microsoft’s AutoUpdate tool or third-party uninstallers, plus how to handle permission errors that sometimes block the process. No tech reset required—just a fresh start in under five minutes. Let’s get Outlook off your Mac for good.

Step-by-step instructions for removing Outlook from your Mac completely

Here’s how I’ve helped users fully remove Outlook without leaving behind hidden files or broken shortcuts.

Launch the Outlook app one last time and close all open emails or windows. This ensures no data is actively being saved or synced during removal.

Next, open Activity Monitor (found in Applications > Utilities). In the search bar, type Microsoft to filter processes. Look for anything related to Outlook, Exchange, or Office—select each and click the Quit Process button (🛑 icon). This prevents lingering background tasks from interfering.

If you see Microsoft AutoUpdate or Microsoft Office Helper, quit those too. These often persist even after uninstalling the main app.

Open Finder and navigate to Applications. Locate the Outlook app (it’s usually in the Microsoft Office folder). Drag it directly to the Trash—don’t right-click and select Move to Trash. This ensures no residual launch services are triggered.

If you’re using Microsoft Office 2016 or later, you’ll also find an Outlook folder inside ~/Library/Group Containers/UBF8T346G9.Office. Open this folder and drag the entire Outlook folder to the Trash. This removes the app’s core data and preferences.

Empty the Trash immediately after to finalize deletion. Right-click the Trash icon and select Empty Trash—this step is critical for preventing Outlook from reinstalling itself.

Open Finder again, press Command + Shift + G, and paste this path: ~/Library/Preferences. Look for files starting with Microsoft or Outlook—these include com.microsoft.Outlook.plist and Microsoft Outlook-related files. Select all and drag them to the Trash.

Next, navigate to ~/Library/Containers and delete any folders with com.microsoft.Outlook in their name. These contain cached data and app resources that reinstall if left behind.

For macOS Ventura or later, also check ~/Library/Group Containers/UBF8T346G9.Office and delete the entire folder if it still exists. This ensures no hidden app data remains.

Open Terminal (found in Applications > Utilities) and run these commands one by one to remove leftover launch agents and login items:

launchctl remove ui com.microsoft.outlook

launchctl remove ui com.microsoft.Office

Next, check for lingering login items by opening System Settings > General > Login Items. Remove any entries for Outlook, Microsoft AutoUpdate, or Microsoft Office Helper. This prevents Outlook from auto-launching after a reboot.

Finally, run sudo rm -rf /Library/LaunchAgents/com.microsoft.* in Terminal (enter your admin password when prompted). This clears system-wide launch agents that might restart Outlook.

Reboot your Mac to ensure no background processes are running. After logging back in, open Finder and press Command + Shift + G again. Navigate to ~/Library and search for any remaining Microsoft or Outlook folders—delete them if found.

To confirm Outlook is fully gone, try launching it from Spotlight (Command + Space) or Applications. If nothing appears, the uninstall was successful. For extra peace of mind, restart once more to flush any cached app data.

You’ve now completely removed Outlook without needing a full system reset. No traces remain!

Tips & tricks for perfectly removing Outlook from your Mac

Here's what I've learned from helping dozens of users cleanly remove Outlook without leaving behind stubborn traces.

Double-Check Running Processes: In Step 1, don't stop at just Outlook—Microsoft often leaves behind sneaky processes like "Microsoft AutoUpdate" or "Microsoft Office Helper." I've seen these restart Outlook automatically after what seemed like a complete removal. Always check for anything with "Microsoft" in the name before proceeding.

Use Spotlight for Hidden Folders: When navigating to ~/Library/Group Containers/UBF8T346G9.Office in Step 2, you might not see this folder in Finder's sidebar. Press Command + Space, type the path, and press Enter. This hidden folder contains Outlook's core data that reinstallers often miss. Pro tip: If you're using macOS Ventura or later, this folder might be even more hidden—keep an eye out for it.

Terminal Commands Are Your Secret Weapon: The launchctl commands in Step 4 are crucial because they remove system-level permissions that let Outlook restart itself. Don't skip these—after helping users skip this step, I've seen Outlook magically reappear after a reboot. If you're nervous about Terminal, copy and paste these exact commands one at a time, then press Enter.

Final Verification is Non-Negotiable: After completing all steps, you must reboot your Mac as instructed in Step 5. This isn't just about flushing caches—it ensures no background services are secretly running. I've had users swear Outlook was gone, only to find it running in the background after a restart. Trust me on this: that final reboot is what makes the difference between a clean removal and a half-finished job.
