Use a Single Installation to Manage Both Accounts

You only need to install the Office suite once on your Mac; the applications allow you to add and switch between multiple accounts seamlessly.

Microsoft 365 on macOS is designed to handle multiple accounts within the same application. You do not need to download separate consumer and business versions of Word, Excel, or PowerPoint.

Install the Office suite once

Download and install the Microsoft Office suite (Word, Excel, PowerPoint, etc.) from the Mac App Store or the official Microsoft website. A single installation covers both personal and business use.

Sign in with your primary account

Launch any Office application, such as Microsoft Word, from your Applications folder. Click on 'Sign In' and enter the credentials for either your Personal or Business account to activate the license.

Add your secondary account

To add your second account, open the application, click on your profile icon in the top corner, or navigate to 'File' > 'New from Template' and click your profile image. Select 'Connect another account' or click the '+' icon and enter the credentials for your other Microsoft 365 account.

Verify your installed version

To check your active license and version details, open an Office app, click the application's name (e.g., 'Word') in the top macOS menu bar, and select 'About Word'.

Use a Single Installation to Manage Both Accounts
