Keep Office Signed In to Maintain Activation

While offline use is fully supported, staying signed in ensures your Office Home & Student 2021 remains activated and functional.

Microsoft Office Home & Student 2021 relies on your Microsoft account for initial activation and license verification. Although you do not need an active internet connection to type or edit documents, explicitly signing out of the software actively removes your license from the local session. This means the next time you open an application, it will ask you to sign in again to verify your license.

Check your current sign-in status

Open any Office application such as Word or Excel, click on the 'File' menu at the top left, and select 'Account' from the bottom of the sidebar.

Verify account details

Under the 'User Information' section, ensure your Microsoft account is displayed. Under 'Product Information', verify it says 'Product Activated'.

Avoid clicking Sign Out

Do not click the 'Sign out' link under your user profile unless you are troubleshooting a specific issue or transferring the license to another computer. If you simply want to work offline, just disconnect from the internet without signing out of the app.

Frequently Asked Questions

What happens if I accidentally sign out of Office Home & Student 2021?

Signing out removes your Microsoft account connection from the software. This deactivates the Office applications, meaning you will not be able to create or edit documents until you launch the software and sign back in with the correct account.

Can I use Office 2021 offline without an internet connection?

Yes, you can use Office Home & Student 2021 offline. Once the software is initially activated over the internet, you do not need a continuous connection to use Word, Excel, or PowerPoint, provided you do not sign out of your account.

Does Office 2021 require monthly online check-ins like Microsoft 365?

No. Unlike Microsoft 365 subscription plans, Office Home & Student 2021 is a one-time purchase. It requires internet access for the initial activation and occasionally to download updates, but it does not mandate a regular monthly online check-in to remain active.
