Best for: anyone buying Office once and wanting it to stay supported for years. This is the newest perpetual Office, and the only version on this page Microsoft still updates.

Supported until October 2029.
Office 2016 and 2019 stopped receiving updates in October 2025, and Office 2021 reaches its end of support on 13 October 2026. Office LTSC 2024 keeps getting security updates through October 2029, which is why it is the version we recommend if the machine is online.

What is in Professional Plus

Word, Excel, PowerPoint, Outlook and OneNote
Access and Publisher, which the Home editions leave out
Improved performance in Excel, a refreshed Outlook and better accessibility tools

Why it is cheaper than our online key.
Only the activation route differs. This key goes through Microsoft’s phone activation service, which takes about two minutes and no phone call — you swap the Installation ID for a Confirmation ID on our Get CID page. The online key version activates instantly over the internet and costs more.

1x genuine 25-character Microsoft Office product key
1x activation code for your free Confirmation ID
Instant email delivery after payment

Long-Term Servicing Channel: the perpetual, buy-once release of Office. Its feature set is fixed at release and it receives security updates only, unlike Microsoft 365 which keeps changing.

No. It is a one-time purchase with a permanent licence. There is nothing to renew and no monthly fee.

Instantly. The key and your activation code are emailed within one to five minutes of payment.

No. Despite the name, you paste the Installation ID into our Get CID page and receive the Confirmation ID online, then type it into the activation wizard.
