Office 2021 Professional Plus Bind Key (Account-Bound)

What you get

After payment you receive your Office 2021 Professional Plus product key by email, instantly in most cases (a system delay can occasionally add 5–10 minutes). The email includes the download link and our activation guide, and the key is also saved under My Account → Keys.

Office 2021 support ends on 13 October 2026

Microsoft’s support end date for Office 2021 is 13 October 2026. After that date Office keeps working, but Microsoft no longer releases security updates or bug fixes for it. If you want updates until 2029, see Office 2024 Professional Plus.

What’s included

• Word, Excel, PowerPoint, Outlook, OneNote, Access and Publisher 2021
• For one Windows 10 or Windows 11 PC

What “account-bound” means

The first time you activate it, this key links Office to your Microsoft account. You then install Office from your account, and if you change computers you can move it to the new PC through your Microsoft account. That’s the difference from our standard Office 2021 Professional Plus key.

How to install and activate

1. Uninstall any other version of Office first, including a preinstalled Microsoft 365 trial (Settings > Apps).
2. Go to setup.office.com, sign in with your Microsoft account (or create one) and enter your product key.
3. Choose your language and click Redeem.
4. Download Office from your Microsoft account and run the installer.
5. Open Word and sign in with the same Microsoft account. Office activates automatically.

If activation fails
