Deactivate an installation of Office

If you have an Microsoft 365 subscription, you can sign out of Office on a PC or Mac remotely from any web browser to deactivate the installation. Because Office will sign you out of devices automatically to stay within your sign-in limit, there's no longer a need to use this process to free up installs. For more info, see How sign in works in Microsoft 365.

Note: Signing out of Office doesn't uninstall Office, remove Office documents, or cancel your Microsoft 365 subscription.

If you're not sure whether your Microsoft 365 version is for home or business, see Office plans.

Microsoft 365 Family or Personal

  1. From any device, go to your Microsoft account, Installs page and sign in using your Microsoft account, if prompted.

  2. Under Devices, select Sign out of Office next to the device.

    It can take up to 72 hours for Office to detect that you signed out remotely.

Microsoft 365 for business

  1. From any device, go to https://portal.office.com/Account/#home and sign in using your work or school account, if prompted.

  2. From the Office apps & devices tile, select View apps and devices.

  3. Under Apps & devices, select the down arrow next to DEVICES to view the devices where Office is installed.

  4. Select Sign out next to the device.

    It can take up to 72 hours for Office to detect that you signed out remotely.

After you sign out of Office, you still can view and print documents from that device, but you won't be able to edit them or create new ones. If you want to use Microsoft 365 on the device, you'll need to sign in to Microsoft 365 when prompted. .

There is no way to deactivate Office Home & Student, Office Home & Business, Office Professional, or individual Office apps. Instead, you must reinstall and activate using the process described in Activate after reinstalling Office.

Stay a step ahead with Microsoft 365
