    Please provide more detail on your requirements.

    Are you trying to uninstall Office on a Windows PC or an Apple Mac computer.

    What version of Office are you uninstalling and what version of Office do you want to install, and what error do you see when you try to do that, please provide a screenshot of any error you may see.

    To uninstall existing Office apps and then run with a new license on a Mac, follow these steps.

    1. Uninstall Office apps
    • Open Finder > Applications.
    • Command+click to select all Microsoft 365/Office for Mac apps (for example: Word, Excel, PowerPoint, OneNote, Outlook).
    • Ctrl+click the selected apps and choose Move to Trash.
    • Empty the Trash.

    If specifically removing Office 2019 for Mac:

    • Quit all Office 2019 apps.
    • Go to Finder > Applications.
    • Right‑click each of these and select Move to Trash:
      • Microsoft Word
      • Microsoft Excel
      • Microsoft PowerPoint
      • Microsoft OneNote
      • Microsoft Outlook (if installed)
    • If Outlook was uninstalled and a local profile is used, delete the Outlook profile from:
      • Library > Group Containers > UBF8T346G9 > Office > Outlook > Outlook 16 Profiles (delete the "Main Profile" folder). This removes locally stored mailbox data.
    1. Remove old license files (if changing or fixing licensing)
    • Download and run the Office license removal tool: Download the license removal tool.
    • Open the downloaded .pkg file from Downloads.
    • If macOS shows an "unidentified developer" warning, Control+click the file and select Open.
    • Select Continue and follow the wizard.
    • When ready, select Install (admin password may be required).
    • After it completes, select Close.
    1. Reinstall Office and activate with the new license Option A – Install from Microsoft account (subscription or one‑time purchase tied to an account)
    • Sign in at the Microsoft account dashboard or Services & subscriptions page with the account that owns the new license.
    • Locate the Office product and choose Install to download the installer.
    • Run the installer and complete setup.
    • Open any Office app and sign in with the same account to activate.

    Option B – Install a perpetual (one‑time) Office for Mac package

    If the goal is to switch from an old one‑time license to a Microsoft 365 subscription, ensure the old license files are removed with the license removal tool, then sign in with the Microsoft 365 account when prompted in an Office app.
