Tip: For Office 365 Home, Personal, and University, see Deactivate an Office 365 Home, Personal, or University install.
You might have installed Office on more than one computer as part of your Office 365 for business subscription and want to deactivate a computer that you're not using anymore. Deactivating an installation isn't the same as uninstalling Office.
After you deactivate an installation, you still can view and print documents from that device, but you won't be able to edit them or create new ones. Office lets you know that the installation is deactivated by showing Unlicensed Product and activation errors in Office.
If you actually want to remove Office, you can do this by following the steps in one of these articles: Uninstall Office 2016, Office 2013, or Office 365 from a PC, Uninstall Office 2011 for Mac, or Uninstall Office 2016 for Mac.
Deactivating an Office 365 for business install
If you're an Office 365 user, do the following to deactivate an installation.
Go to https://portal.office.com/Account/#home. If prompted, sign in with your work or school account.
From the Install status tile, select Manage installs.
Under Install status, select Deactivate to deactivate the Office installations you no longer use.
If you're concerned about deactivating an install on your own, contact your Office 365 admin to help with the deactivation. If, after contacting and working with your admin, you still can't deactivate an install, contact Office support.
If you have Office 365 admin privileges, refer to the following blog article to manage a user's Office 365 installs via the Admin Center: Office 365 ProPlus User Activations Management.
