Activate Office 2016 for Mac
If you haven't already installed Office 2016 for Mac, here's how:
Activate Office 2016 for Mac
Click the Launchpad icon in the Dock to display all of your apps.
Click the Microsoft Word icon in the Launchpad.
The What's New window opens automatically. Click Get Started to start activating.
Click Sign in.
Enter the email address you used for your Microsoft account or the account assigned to you by your work or school, and click Next.
Enter the email address and password you used for your Microsoft account or the account assigned to you by your work or school, and click Sign in.
The system checks if you have a valid license.
Important: If you have multiple licenses, please follow the steps in the Activate with multiple licenses section.
After the license validates, it will activate the product.
On the next screen, choose a theme for your Office install, and then click Continue.
You're done! Click Start Using Word, to open and start using the app.
Tip: To make the Office apps easy to launch, you can add the Office for Mac app icons to the dock.
Activate with multiple licenses
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 Office 2016 for Mac Home and Student or Home and Business install on one Mac licenses.
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 from your subscription while you can't deactivate a one install license. 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 the list.
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.
If you have multiple licenses, all licenses will be shown, and you can select the license you want to use.
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.
Multiple licenses and key already used
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 is now grayed out. You can select any other license that hasn't been used.
