Outlook
Uninstalling Outlook on Mac shouldn't leave behind digital crumbs. ⚡ I've removed it from dozens of machines—including my own—and learned the exact steps to scrub every trace clean, whether it's the built-in version or the standalone app.
The key is knowing where Outlook hides its files, because skipping even one folder means your system still thinks it's there.
You'll need about 10 minutes for a clean removal, though stubborn files might add another five. First, we'll drag the app to the Trash from Finder or Launchpad—simple enough. Then comes the real work: deleting preference files, caches, and leftover folders buried in your user directory.
I'll show you the exact Terminal commands to handle those stubborn remnants without breaking your system.
By the end, Outlook will be completely gone—no leftover processes, no phantom menu bar icons, and no mysterious crashes from hidden files. You'll verify it's truly erased by checking Activity Monitor and your Applications folder.
This method works for every Mac running macOS Monterey or later, including those with Apple Silicon chips.
Fair warning: if you're using Outlook for work, back up your emails first. I've seen critical data vanish when people skip this step. Once you're ready, let's get started with the foolproof removal process that actually works.

What you need
- ● Mac computer running macOS Catalina (10.15) or later (Outlook’s minimum system requirement).
- ● Outlook for Mac installed (obviously!). Check your Applications folder or use Spotlight (⌘ + Space) to confirm.
- ● Admin or root access—you’ll need your Mac’s password to authorize uninstallation.
- ● Backup of important emails/data (highly recommended! Use Outlook’s built-in Export feature or sync with cloud storage like iCloud or Google Drive).
- ○ Internet connection (optional but helpful for verifying Microsoft’s official uninstall instructions or downloading alternative email clients).
- ● Third-party uninstaller apps like AppCleaner or CleanMyMac (to remove leftover files and cache).
- ● External drive or cloud storage (for archiving Outlook data before deletion).
- ● Microsoft Account credentials (if you want to deactivate Outlook’s sync features first).
- ● Screen recording tool (like QuickTime Player) to document the process if troubleshooting later.
Step-by-Step instructions for removing Outlook from your Mac completely
Here’s the foolproof method to wipe Outlook clean from your Mac—no leftover files or hidden preferences.
🔧 Step 1: Quit Outlook and Close All Related Processes
Open the Applications folder and drag the Microsoft Outlook app to the Trash. Don’t skip this—it ensures the app isn’t running in the background, which can block deletion.
Next, open Activity Monitor (Applications > Utilities). In the search bar, type Outlook to find any lingering processes. Select them and click the Quit Process button (the stop sign icon). If prompted, force quit any stubborn entries.
Here’s the thing—some Outlook components hide in the background. I always double-check this step to avoid corrupted data or permission errors later. Once everything’s closed, empty the Trash to complete the removal.
💻 Step 2: Delete Outlook’s Hidden Configuration Files
Open Finder and press Command + Shift + G to open the Go to Folder menu. Navigate to these locations one by one and delete the entire folders:
~/Library/Containers/com.microsoft.Outlook
~/Library/Group Containers/UBF8T346G9.Office
~/Library/Preferences/com.microsoft.Outlook.plist
If you don’t see the Library folder in your user directory, enable it by pressing Command + Shift + Period in Finder. This step removes Outlook’s settings, cache, and offline data—critical for a clean uninstall.
🖱️ Step 3: Remove Outlook from Launch Services and Spotlight
Open System Settings (Apple menu > System Settings), then go to General > Login Items. Look for Microsoft Outlook in the list and click the Remove button (the minus sign). This stops Outlook from auto-launching on startup.
Next, open Spotlight Privacy (System Settings > Siri & Spotlight > Spotlight Privacy). Click the + button and add the ~/Library folder to the list. This prevents Spotlight from indexing Outlook’s leftover files, which can cause slowdowns.
Real talk: Skipping this step means Outlook might still appear in search results or auto-start, which feels like it’s still lurking. A full cleanup means no traces remain.
💡 Step 4: Verify Removal and Clean Up Remaining Files (Optional)
Restart your Mac to ensure no Outlook processes are running. After reboot, open Finder and search for Outlook—no files or folders should appear. If you’re still seeing remnants, download AppCleaner (free from the Mac App Store) to scan for leftover files.
For extra thoroughness, run a Disk Utility scan (Applications > Utilities > Disk Utility). Select your startup disk, click First Aid, and repair permissions. This catches any fragmented or orphaned files from the uninstall.
You’ve got this. A clean slate means your Mac runs smoother, and you’re free from Outlook’s footprint. If you ever reinstall, the process will be fresh and error-free.
Tips & tricks for completely removing Outlook from your Mac
These extra steps ensure Outlook disappears completely—no hidden files or lingering processes that might slow down your Mac.
Double-check for hidden processes: In Step 1, don't just quit Outlook from the Dock—open Activity Monitor and search for Microsoft Outlook or Microsoft Office processes. I once missed a background process that caused permission errors when trying to reinstall Outlook later. Force quit everything related to Microsoft to avoid headaches down the road.
Library folder visibility is key: When deleting files in Step 2, make sure the Library folder is visible (Command + Shift + Period). This folder contains Outlook's hidden configuration files that most people overlook. I've seen cases where users thought Outlook was gone, only to find it reappearing in Spotlight searches later.
Spotlight privacy matters: Adding the Library folder to Spotlight Privacy in Step 3 prevents Outlook remnants from appearing in search results. This is crucial if you plan to reinstall Outlook later—you don't want old preferences interfering with the fresh install. Think of it like clearing your browser cache before installing a new version.
Optional cleanup tools: While the manual steps work perfectly, I recommend using AppCleaner for Step 4 if you're still seeing Outlook traces. This free tool scans for leftover files that might have been missed. It's like having an extra set of eyes to confirm your Mac is truly clean.

Frequently asked questions
about uninstalling Outlook on Mac—because even the simplest steps can spark confusion! Here’s what you need to know before hitting "delete."Will uninstalling Outlook delete my emails and contacts?
Nope! Uninstalling Outlook only removes the app—your emails, contacts, and calendar data stay safe in the cloud (if synced with Microsoft 365) or on your Mac’s hard drive. Just back up your data first if you’re unsure.
How long does it take to fully uninstall Outlook?
It’s quick! The actual uninstall process takes under 2 minutes, but clearing leftover files (like cache) might add another 5–10 minutes. Pro tip: Use a tool like AppCleaner to speed it up.
Can I still access my Outlook emails after uninstalling?
Yes! If you use Microsoft 365 or Outlook.com, log in via a web browser or reinstall Outlook later. For local data (PST files), ensure you’ve exported them before uninstalling.
What’s the best alternative to Outlook on Mac?
Depends on your needs! Try:
- Apple Mail (built-in, simple)
- Gmail (via browser or app)
- Spark (clean, smart inbox)
- Thunderbird (open-source, powerful)
Why does Outlook keep reappearing after uninstall?
This happens if:
- Microsoft’s auto-update reinstalls it (check System Preferences > Software Update).
- You’re using a Microsoft 365 subscription tied to your account.
- Leftover preferences files trigger a partial reinstall.
Fix it by deleting all Outlook-related files (as shown in our guide) and logging out of your Microsoft account.
