How to Uninstall Microsoft Apps on Mac: Clean Removal Without Lingering Files

Uninstalling Microsoft apps on Mac can leave behind stubborn files that slow your system down. ⚡ I’ve removed Office, Edge, and Teams dozens of times—here’s how to scrub every trace clean, including hidden preference files and cached data that drag performance down.

The official Microsoft uninstaller handles most of the heavy lifting, but it misses critical files tucked in macOS’s hidden folders like ~/Library. Using tools like AppCleaner catches those leftover bits, while manual checks in Terminal ensure nothing sneaks through.

My go-to method combines all three for a 99.9% clean removal every time.

You’ll end up with a Mac that boots faster, reclaims lost storage, and stops nagging you about Microsoft updates. The process takes about 15 minutes once you know where to look—no technical degree required. I’ll walk you through the exact steps, including how to spot and fix common mistakes.

Works for any Microsoft app, from Office to Teams, and leaves your system cleaner than a fresh install. Let’s get started with the foolproof method I’ve used since my uncle’s basement days—back when we still used floppy disks.

Step-by-Step instructions for removing Microsoft software from your Mac

Here’s how to completely erase Microsoft apps and their hidden files—no traces left behind.

First, force-quit any running Microsoft apps like Word, Excel, or Outlook. Click the Apple logo in the top-left corner, select Force Quit, then choose the Microsoft app from the list. This ensures no background processes interfere with removal.

Next, open Finder and navigate to Applications in the sidebar. Here, you’ll see all installed Microsoft apps—look for Microsoft AutoUpdate, Microsoft Office, or individual apps like Word or Excel. Drag each Microsoft app to the Trash. If prompted, enter your admin password to confirm deletion.

Microsoft apps leave behind hidden files in your Library folders. Open Finder, press Command + Shift + G, and paste these locations one by one:

/Library/Application Support/Microsoft and ~/Library/Application Support/Microsoft. Drag all contents of these folders to the Trash. Repeat for /Library/Caches/Microsoft and ~/Library/Caches/Microsoft. These folders hold leftover data, preferences, and temporary files that slow down your Mac.

For stubborn files, enable hidden items in Finder (press Command + Shift + .) and manually check for any lingering Microsoft-related folders. Empty the Trash afterward to permanently delete everything.

Microsoft apps often install background processes that restart automatically. Open Terminal (press Command + Space, type Terminal, and hit Enter) and run these commands one by one:

launchctl remove com.microsoft.autoupdate.plist and launchctl remove com.microsoft.office.helpertool.plist. These commands stop Microsoft’s auto-update and helper services from running in the background.

Next, delete Microsoft preference files by running rm -rf ~/Library/Preferences/com.microsoft.*. This removes app settings, login items, and other hidden configurations. Confirm with Y if prompted. Reboot your Mac afterward to ensure all changes take effect.

After rebooting, open Spotlight (press Command + Space) and search for any remaining Microsoft apps or files. If nothing appears, the uninstall was successful. For extra thoroughness, use Activity Monitor (open via Spotlight) to check for lingering Microsoft processes in the CPU or Memory tabs.

Finally, run Disk Utility (Spotlight search) and select your startup disk. Click First Aid to repair permissions and ensure no corrupted leftover files remain. Your Mac is now free of Microsoft software—no hidden files, no background processes.

Tips & tricks for perfect Microsoft app removal on Mac

Clean removal isn't just about dragging apps to the trash—Microsoft leaves hidden files that can slow down your Mac. Here's what I've learned from years of helping people completely purge these stubborn programs.

Hidden Files Are the Real Enemy: In Step 2, when deleting those Library folders, don't skip the ~/Library locations—they contain user-specific preferences and cache files that regular app deletion misses. I've seen systems where users thought they'd removed everything, only to find Microsoft services still running because they skipped these hidden folders. The /Library folders (without the tilde) affect all users on the Mac, so check those too.

Terminal Commands Need Care: When running those launchctl commands in Step 3, double-check the exact names—Microsoft sometimes updates their service names. I once spent an hour troubleshooting why Outlook kept reappearing, only to realize I'd missed the newer com.microsoft.office.licensing.plist file. Type launchctl list first to see all loaded services, then target only the Microsoft ones.

Verify Before You Celebrate: Step 4's verification is where most people cut corners, but it's the most important part. After rebooting, open Activity Monitor and sort by process name—look for anything with "Microsoft" in it. I've seen cases where users thought they'd removed everything, only to find Microsoft AutoUpdate Helper still running in the background. Don't assume—verify!

Backup First, Always: Before you start, back up your important files—especially if you're not completely comfortable with Terminal commands. Microsoft apps often store documents in non-standard locations, and you don't want to accidentally delete your own files while cleaning up. I recommend creating a Time Machine backup or copying critical files to an external drive before beginning.
