Outlook
To uninstall Outlook on Mac properly, you’ll need 15 minutes and a trash can—both literal and digital. ⚡ I’ve helped enough users wrestle with Outlook’s stubborn remnants to know the right way: drag it to the trash won’t cut it.
Microsoft’s app leaves behind preference files, caches, and hidden folders that can cause crashes or data leaks later. The key is knowing exactly where to look—and what to delete.
Start by backing up your Outlook data (File > Export > Export to Archive) and closing the app completely. Then, we’ll tackle three uninstall methods: the standard drag-to-trash approach, a deeper Finder cleanup, and a Terminal command for stubborn files.
I’ll walk you through each step, including how to handle macOS permission errors that trip up most users. No third-party tools required—just your Mac’s built-in tools and a little patience.
After uninstalling, we’ll verify everything’s gone by checking the Applications folder, Library folders (including hidden ones), and even the LaunchAgents directory where Outlook hides its background processes. You’ll end up with a clean system—no lingering Outlook files, no mysterious crashes, and no wasted space.
Trust me, this method has saved more users from tech support calls than I’d like to admit.
If Outlook fights back with errors or won’t quit, we’ll troubleshoot those too—like force-quitting stubborn processes or fixing permission issues. By the end, your Mac will feel lighter, and you’ll know exactly where Outlook hid its digital fingerprints. Ready to start?

Step-by-Step instructions for removing Outlook from your Mac
Here's the clean, foolproof method I use to completely wipe Outlook from your Mac.
🔧 Step 1: Close Outlook and Quit Related Processes
Launch the Outlook app and go to Outlook in the menu bar, then select Quit Outlook. This ensures no data is being actively written during removal. I always double-check by opening Activity Monitor (Applications > Utilities) and searching for any lingering Microsoft Outlook processes.
Force quit any remaining Outlook processes you find. This prevents errors during the actual uninstall. If you see Microsoft Outlook Helper or Office Helper processes, end those too. The goal is to have zero Outlook-related processes running before proceeding.
🖥️ Step 2: Remove Outlook Using the Microsoft Auto Uninstaller
Download Microsoft's Office Uninstaller Tool from their official support site. Save it to your Downloads folder. Open the downloaded file and follow the on-screen instructions to select Outlook for removal. This tool handles the heavy lifting of removing all core files.
Wait for the process to complete—it typically takes 2-5 minutes depending on your Mac's speed. You'll see a confirmation screen when it's done. Don't restart yet; we still need to clean up remaining files manually.
💡 Step 3: Delete Remaining Outlook Files and Folders
Open Finder and navigate to your Applications folder. Locate the Microsoft Outlook app (it might be in a Microsoft Office folder) and drag it to the Trash. Empty the Trash immediately to permanently remove it.
Next, open Go in Finder's menu bar, then press Shift+Command+G to open the Go to Folder dialog. Delete these remaining folders one by one: ~/Library/Containers/com.microsoft.Outlook/, ~/Library/Group Containers/UBF8T346G9.Office/, and ~/Library/Application Support/Microsoft/Office/.
⌨️ Step 4: Remove Outlook from Launchpad and Accounts
Open Launchpad and locate the Outlook icon. Click and hold until all icons start wiggling, then tap the X on the Outlook icon to remove it from Launchpad. This prevents accidental launches later.
Go to System Settings (or System Preferences on older macOS), then select Mail. If Outlook is listed as an email account provider, remove it from the accounts section. This ensures no email syncing occurs after uninstall.
⏰ Step 5: Verify Complete Removal and Clean Up
Restart your Mac to ensure all changes take effect. After reboot, open Spotlight (Command+Space) and search for Outlook. If nothing appears, the uninstall was successful. For extra thoroughness, run a search for Microsoft Outlook in your entire drive using Finder's search.
Finally, empty your Trash one last time to clear any residual files. You've now completely removed Outlook from your Mac—no leftover files or hidden processes.
Tips & tricks for completely removing Outlook from your Mac
Here's what I've learned from helping dozens of users completely wipe Outlook from their Macs—these tricks ensure no hidden files or processes slip through the cracks.
Double-Check for Hidden Processes: In Step 1, when you're using Activity Monitor, don't just look for "Outlook"—search for Microsoft Outlook Helper and Office Helper too. I once missed one of these and Outlook kept launching automatically every time I opened my Mac. Trust me on this: you want zero Outlook-related processes running before proceeding.
Backup Critical Data First: Before you delete any Outlook folders in Step 3, I strongly recommend backing up your Outlook data. Use File > Export in Outlook to create a backup of your emails, contacts, and calendar. You can also copy the entire ~/Library/Application Support/Microsoft/Office folder to an external drive before deleting it. Better safe than sorry—especially if you have important emails or contacts stored there.
Use Spotlight for Final Verification: After you've gone through all the steps, including emptying the Trash, use Spotlight (Command+Space) to search for Outlook one last time. This catches any remaining references that might not have been fully removed. I've seen Outlook files hide in unexpected places—don't skip this final check!
Consider a Full System Search: For the most thorough cleanup, use Finder's advanced search. Go to Finder > File > New Search for Finder, then search for kind:application and name:outlook. This will find any hidden application files that might still be lurking on your system. This step is especially important if you're planning to reinstall Outlook later and want a clean slate.

Frequently asked questions
Got questions about uninstalling Outlook on Mac? You’re not alone! Here are answers to the most common concerns—so you can clean up your system with confidence.
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/Exchange) or on your Mac (if stored locally). Just don’t drag the app to Trash without backing up first if you’re unsure.
How long does it take to fully uninstall Outlook?
Uninstalling the app itself takes under 5 minutes, but removing all leftover files (like cache or preferences) might take a few extra minutes. Use a tool like AppCleaner to speed it up—it scans and deletes related files in one click.
Can I reinstall Outlook later if I change my mind?
Just download Outlook again from Microsoft’s website. Your account will still be linked, and you’ll sign in to recover your data. Think of it like pausing a show—you can always come back!
What if Outlook won’t uninstall normally?
If Outlook freezes or crashes during uninstall, force-quit it (Command + Option + Esc), then try again. If that fails, boot your Mac in Safe Mode (hold Shift at startup) to uninstall—this stops background processes from interfering.
What’s a good alternative to Outlook for Mac?
Love Outlook’s features but want to switch? Try these free/paid options:
- Apple Mail – Seamless for iCloud/Exchange users.
- Spark – Clean interface with smart inbox organization.
- Thunderbird – Open-source with robust email management.
- Gmail (via browser) – No install needed if you’re a Google fan.
