Reset Office Trial Without Reinstalling macOS :star:

Introduction

If you’re trying to reset the trial version of Microsoft Office for Mac without reformatting your system, you can attempt it by clearing hidden licensing data. This guide explains the files to delete and why some common uninstall methods don’t work.

Simplified One-Line Flowchart

Install Office ➔ Activate trial ➔ Delete hidden license files ➔ Reinstall ➔ Retry trial

Easy Step-by-Step Method

Step 1: Uninstall Microsoft Office

  • Delete the entire Microsoft Office folder from /Applications.
  • Also remove supporting files from:
    • /Library/Preferences/
    • ~/Library/Preferences/
    • ~/Library/Application Support/

Step 2: Delete the Licensing File

  • Locate and remove the file:
    /Library/Preferences/com.microsoft.office.licensing.plist
  • This file stores your license or trial activation status system-wide.

Step 3: Remove Additional Licensing Caches (Optional)

  • Check for any Microsoft-related files in:
    • /Library/Application Support/Microsoft/
    • /private/var/db/receipts/
  • Be cautious: deleting system files may affect other software.

Step 4: Reinstall Office

  • Use your original Office installer to reinstall.
  • Do not restore preferences from backup, as this might reintroduce licensing data.

Step 5: Try Activating Trial Again

  • Launch an app like Outlook.
  • If prompted, attempt trial activation. If it fails, the licensing flag may still be detected elsewhere in the system.

Quick Tips (Optional)

  • Installing as a guest user doesn’t help — the licensing data is not stored in the user folder.
  • Reinstalling just one component (e.g., Outlook) is faster but often won’t bypass the license lock.
  • Some users reported no luck with removal tools alone; manual deletion is more effective.

Important Notes

  • Trial flags are often stored in system-level files, not just user data.
  • Some components may write hidden flags that are not easily removed.
  • This method does not guarantee success on all macOS versions.
  • Be very careful when deleting system files — always back up your Mac beforehand.

ENJOY & HAPPY LEARNING! :heart:
