Question details
The user is unable to activate Microsoft 365 applications on a new Mac, even though the subscription is valid and works on other devices.
- Product

- Device & OS

- Scenario
- Setting up Microsoft Office applications on a newly purchased Mac device.

Use the Office License Removal Tool
Clear out conflicting or corrupted license files using Microsoft's official tool to allow a fresh activation on your new Mac.
Often, hidden corrupted license files or remnants from pre-installed software can prevent a new activation from going through. Microsoft provides a dedicated utility to wipe these old licenses clean.
Go to the Microsoft services and subscriptions page in your web browser. Log in to confirm that your Microsoft 365 subscription is active and tied to the account you are using.
Download the official Microsoft Office License Removal Tool for Mac from the Microsoft support website.
Open the downloaded .pkg file and follow the on-screen prompts to install and run the tool. This will remove all Office license files from your Mac.
Launch any Office application, such as Microsoft Word. Click 'Sign In' when prompted and enter the credentials for your active Microsoft 365 account to activate the software.
Reinstall Microsoft 365 for Mac
If removing the license files does not resolve the issue, a clean reinstallation can fix corrupted application files.

Frequently Asked Questions
Why does my Microsoft 365 subscription work on my iPhone but not my new Mac?
Office licenses can sometimes get stuck or conflict with pre-installed cache on a new Mac. While mobile activations are handled through the App Store or mobile app credentials, macOS uses a different local license file system that may require clearing with the License Removal Tool.
How many Macs can I activate with one Microsoft 365 subscription?
A Microsoft 365 Personal or Family subscription allows you to install and activate Office applications on up to 5 devices simultaneously per user, which can be a mix of Macs, PCs, tablets, and phones.
Do I need an active internet connection to activate Microsoft 365 on Mac?
Yes, a stable internet connection is required the first time you sign in to activate. The software must communicate with Microsoft's servers to verify that your subscription is active and valid.
