How To Uninstall Office From Mac: Complete Removal Guide

Completely removing Microsoft Office from macOS requires moving primary application binaries to the Trash and manually purging hidden user library containers, preference files, and activation credentials. Executing a full purge clears between 6 GB and 10 GB of system storage while resolving persistent activation conflicts, app crashes, and update errors. Following standard macOS file system management procedures guarantees a clean environment for reinstallation or final removal without altering personal user documents.

Pre-Uninstallation Planning & Data Safeguards

A standard drag-and-drop uninstallation on macOS leaves behind gigabytes of cached data, database indexes, background daemons, and system preference configurations. While deleting the application icons from the Applications folder frees up minimal space, residual files stored deep within the system user profile can cause activation loops when installing new versions of Microsoft 365, Office 2021, or Office 2019.

Before executing a complete file removal, perform local backups of non-cloud synchronized data. Outlook users holding local mail folders, custom signatures, or offline archives must back up their profile data manually. Word, Excel, and PowerPoint documents stored in local directories like Documents or Desktop remain safe during application removal, but files saved inside the localized container directories will be permanently erased if not properly identified.

Pre-Removal Checklist

• Required Administrator Credentials: You must have the macOS system administrator password to remove privileged helper tools and background update agents.
• Target Applications: Microsoft Word, Microsoft Excel, Microsoft PowerPoint, Microsoft Outlook, Microsoft OneNote, Microsoft OneDrive, and Microsoft AutoUpdate.
• Outlook Data Backup: Export local emails, contacts, and calendar items into an .olm file via File > Export within Outlook, or locate the main identity folder located inside ~/Library/Group Containers/UBF8T346G9.Office/Outlook/Outlook 15 Profiles/.
• Open Files and Process Termination: Ensure all active Office files are saved and closed across all logged-in user accounts on the Mac.
• Estimated Execution Duration: 10 to 15 minutes for a full manual directory purge.

Complete macOS Microsoft Office Purge Workflow

Step 1: Terminate Active Microsoft System Processes

Background daemons and auto-update processes can lock application files in memory, preventing system modifications or triggering file-in-use errors during deletion.

1. Open Activity Monitor using Spotlight (press Command + Spacebar, type "Activity Monitor", and press Return).
2. Click the Search bar in the upper-right corner of Activity Monitor and type "Microsoft".
3. Select any running processes associated with the suite, including Microsoft AutoUpdate, Microsoft Outlook Service, or Office365ServiceV2.
4. Click the Stop icon (the octagon containing an 'X') in the top toolbar.
5. Select Force Quit to immediately end the selected background processes.

Warning: Do not skip process termination. If Microsoft AutoUpdate or OneDrive background tasks remain active, macOS will reject attempts to clear related system libraries, resulting in orphaned system launch daemons.

Step 2: Remove Core Applications from the Applications Directory

Deleting the main software executables is the primary step in clearing high-density binary files from your primary drive storage.

1. Open Finder and navigate to the Applications folder in the sidebar.
2. Hold down the Command key and click each Microsoft application icon:
   
   
   • Microsoft Word
   • Microsoft Excel
   • Microsoft PowerPoint
   • Microsoft Outlook
   • Microsoft OneNote
   • OneDrive (if no longer required for general system storage)
3. Right-click (or Control-click) any selected application icon and choose Move to Trash.
4. Enter your administrative macOS account password if prompted to confirm the deletion.

Step 3: Purge User Library Containers and Cached Data

The majority of Microsoft Office user data, configuration flags, local caches, and temporary saved states reside within your user profile's hidden Library folder.

1. Bring Finder to the foreground.
2. Press Shift + Command + G simultaneously to open the Go to Folder navigation bar.
3. Type the exact user library path ~/Library and press Return.
4. Open the Containers subfolder within this directory.
5. Move the following target folders to the Trash by searching for them or selecting them manually:
   
   
   • com.microsoft.errorreporting
   • com.microsoft.Excel
   • com.microsoft.netlib.shipassertprocess
   • com.microsoft.Office365ServiceV2
   • com.microsoft.Outlook
   • com.microsoft.Powerpoint
   • com.microsoft.RMS-XPCService
   • com.microsoft.Word
   • com.microsoft.onenote.mac

Pro-Tip: On macOS Big Sur, Monterey, Ventura, Sonoma, and later, many container folders display localized application names in Finder instead of the explicit bundle identifiers listed above. If you see folders named Word, Excel, or PowerPoint inside the Containers directory, move those directly to the Trash.

Step 4: Delete Microsoft Group Containers and Shared Profiles

Group Containers store shared resources, system fonts, licensing data, and local Outlook database profiles. Clearing these folders is necessary to complete a clean reset.

1. While still inside the ~/Library directory via the Go to Folder tool, locate and open the Group Containers folder.
2. Locate the folders beginning with the string identifier UBF8T346G9.
3. Select and move the following directories to the Trash:
   
   
   • UBF8T346G9.ms
   • UBF8T346G9.Office
   • UBF8T346G9.OfficeOsfWebServer
4. Confirm that no lingering custom identity templates or unsaved local drafts remain inside UBF8T346G9.Office/Outlook/ before final deletion.

Step 5: Clean Licensing Files and AutoUpdate System Launch Services

To prevent new installations from automatically binding to corrupted licenses or broken updater services, remove system-level launch agents and keychains.

1. Press Shift + Command + G in Finder and type the global root path /Library (note the absence of the tilde prefix).
2. Open LaunchDaemons and move com.microsoft.autoupdate.helper.plist to the Trash.
3. Open PrivilegedHelperTools within /Library and move com.microsoft.autoupdate.helper to the Trash.
4. Navigate to /Library/Preferences/ and delete com.microsoft.autoupdate.fba.plist.
5. Launch the Keychain Access app via Spotlight.
6. Search for "Microsoft" in the upper right search bar.
7. Delete entries labeled Microsoft Office Licenses, com.microsoft.adal.cache, and any item referencing Microsoft365.
8. Empty the Trash and restart your Mac to complete the uninstallation process.

The following structural reference breaks down the system footprint of Microsoft Office on macOS, highlighting the precise directory paths, storage impact, and necessity level for manual removal.

Troubleshooting Common macOS Office Removal Errors

Scenario 1: Finder displays "The item cannot be moved to the Trash because it's open"

• Root Cause: A background daemon, such as Microsoft AutoUpdate or OneDrive file synchronization, is currently referencing a open handle inside the application package.
• Actionable Fix: Open Activity Monitor, filter by the term "Microsoft", click the Force Quit button on all matched entries, then attempt deletion again. If the issue persists, boot the Mac into Safe Mode (hold Shift on Intel Macs, or hold the Power button on Apple Silicon Macs) and perform the removal steps from there.

Scenario 2: Reinstallation triggers an immediate activation loop or license error

• Root Cause: Corrupted licensing token keys remain saved inside the hidden macOS Keychain or within the UBF8T346G9.Office Group Container.
• Actionable Fix: Download and run Microsoft's official Office License Removal Tool executable, or open Keychain Access manually, search for "adal", "Microsoft", or "Office", and delete all matching credentials. Follow this by clearing the UBF8T346G9.Office folder in ~/Library/Group Containers/.

Scenario 3: Local Outlook folders disappear after deleting Group Containers

• Root Cause: Moving UBF8T346G9.Office to the Trash removes the active local database file housing offline messages, signatures, and folders not synchronized to an IMAP/Exchange server.
• Actionable Fix: Open the Trash immediately, locate the UBF8T346G9.Office folder, right-click it, and select Put Back. Open Outlook, choose File > Export, save your backup .olm file to an external location or the Desktop, and then proceed with the cleanup steps.

Scenario 4: Microsoft AutoUpdate continues popping up after removing all applications

• Root Cause: The application launcher daemon stored in system-level Library launch folders was not purged alongside the core apps.
• Actionable Fix: Navigate to /Library/LaunchAgents and /Library/LaunchDaemons via Finder's Go to Folder menu, delete com.microsoft.autoupdate.helper.plist, and restart the computer.

Frequently Asked Questions

Does uninstalling Office from a Mac delete my personal Word and Excel documents?

No. Personal documents, spreadsheets, and presentations created using Microsoft Office are stored in user-designated locations such as the Documents folder, Desktop, or external cloud storage like iCloud Drive and OneDrive. Uninstalling application files and clearing system containers leaves these personal user files intact.

How do I remove only the license registration from my Mac without deleting the apps?

To reset licensing configurations while keeping the applications installed, run the official Microsoft License Removal Tool. Alternatively, delete the licensing credentials inside Keychain Access and clear the hidden file located at * /Library/Preferences/com.microsoft.office.licensingV2.plist*. The next time you launch any Office application, you will be prompted to sign in with a new account.

Why is Microsoft AutoUpdate still running after I deleted Word and Excel?

Microsoft AutoUpdate is installed as a separate system-level helper application stored outside the standard main application bundle. To completely remove it, delete the updater tool located at /Library/Application Support/Microsoft/MAU2.0/ alongside its associated launch agents in /Library/LaunchAgents and /Library/LaunchDaemons.

Can I remove Microsoft Outlook while keeping Word and Excel intact?

Yes. You can selectively delete individual applications by opening the Applications folder and moving only Microsoft Outlook.app to the Trash. However, shared preferences stored in Group Containers will remain intact, meaning Outlook settings will persist if you decide to reinstall it later.

How do I access the hidden ~/Library folder on macOS?

Open Finder, click Go in the top menu bar, hold down the Option key on your keyboard to reveal the hidden Library menu item, and click it. Alternatively, press Shift + Command + G inside Finder, type ~/Library, and press Return.
