For Office 2016 for Mac, you can have up to 25 licenses associated with the same Microsoft account: only one license for an Office 365 subscription and multiple one-time-use installs of Office 2016 for Mac Home and Student or Home and Business.
If you have multiple Mac licenses associated with the same Microsoft account, it's best to start with an Office 365 subscription since you can always deactivate an installation. A one-time-use license can not be deactivated. If you don’t have an Office 365 subscription, start by using the license at the top of the list and moving your way down.
There isn't a way to track your one time licenses so we recommend you keep a list as to which license is activated on which device. If you don’t remember which license was used, you'll have to go through a process of elimination to determine which ones you've used so far.
Choose the license you want to use. (We highly recommend choosing an Office 365 license if you have one.)
After the license validates, it will activate the product, and you can click Start Using Word to open and start using Office 2016 for Mac.
If you try to activate Office 2016 for Mac one time install and you get the error: Key already used, you will need to select another license to use. Click Cancel and you'll return to the license selection screen.
The license that you tried to use will be grayed out. You can select any other license that hasn't been used.
If you haven't redeemed your product key for Office 2016 for Mac, you'll want to do that before trying to activate. Follow these steps:
Step 1: Go to https://www.office.com/setup
Step 2: Sign in with your Microsoft account, or create one if you don't have one (you can create one with any existing email address you already have). Be sure to remember this account so that you can install or reinstall Office later, without a product key.
Step 3: Enter your Office product key, without hyphens.
Step 4: Follow the prompts to finish the redemption process.
