Term and updates
You purchase this version of Office once and use it without a subscription. A Microsoft 365 subscription or a free upgrade to later versions is not included. Unlimited use does not mean that Microsoft will provide security updates indefinitely.
Microsoft support
Microsoft support for Office 2021 (including Publisher) ends in October 2026. After that, there will be no further security updates. For new workstations, we recommend a current version such as Office 2024. Office 2024 no longer includes Publisher.
Check before you buy
Please check your operating system, processor architecture and the compatibility of your add-ins. Uninstall any existing Office versions that conflict with the installation and follow the instructions for exactly this edition. The licence is valid for Windows only, not for Mac.
Download and activation
Once payment is received, you receive the product key, download link and an illustrated installation guide by email. Install Office 2021 Standard on each licensed PC and activate it with the same key. If you have any questions before installing, our support team will be happy to help.
Optional: delivery on a USB stick
On request, you receive the software and codes on a USB stick – sent by registered post, within Germany only, usually in 2–3 working days, free shipping (included in the price). The codes are then sent by post instead of by email.
Invoice
You receive an invoice with every order. VAT depends on the country of delivery and the customer's status; the amount shown at checkout applies.
The product image is for illustration purposes only. Without a USB stick, delivery is purely digital, with no physical media or packaging.
