Which apps are included in Office 2021 Standard?

Office 2021 Standard includes six desktop apps: Word, Excel, PowerPoint, Outlook, OneNote and Publisher. Access isn't included; it is only in Professional Plus. Microsoft has announced that Publisher will no longer be supported after October 2026, so plan ahead if you rely on it.

App	What you use it for
Word	Documents, letters, reports and CVs
Excel	Spreadsheets, budgets, formulas and charts
PowerPoint	Presentations and slide decks
Outlook	Email, calendar and contacts
OneNote	Notes, notebooks and to-do lists
Publisher	Flyers, newsletters and print layouts

What's the difference between Office 2021 Standard and Professional Plus?

The only app difference is Access: Professional Plus includes it and Standard doesn't. If you never build or open Access databases, Standard already gives you every other app. Both Office 2021 editions include Publisher.

	Office 2021 Standard	Office 2021 Professional Plus
Word, Excel, PowerPoint, Outlook, OneNote	Included	Included
Publisher	Included	Included
Access	Not included	Included
Runs on	Windows PC	Windows PC
Payment	One-time purchase	One-time purchase

A question we often get is whether Standard can open Access files. It can't: .accdb databases need Access, which only Professional Plus includes.

How does the 5-50 PC volume licence work?

This volume option lets you license between 5 and 50 computers in one order. You choose the number of PCs when you order, and the email you receive after payment contains your licence key and step-by-step instructions for that number of computers.

Every covered PC runs the same edition, Office 2021 Standard, which keeps setup and support consistent across an office. Volume editions can be activated inside an Office app or from the command line, which saves time when IT staff set up many PCs.

Is Office 2021 still supported by Microsoft?

Office 2021's end-of-support date is 13 October 2026, for both the Windows and Mac versions. From that date, Microsoft no longer releases security updates, bug fixes or technical support for it. The apps keep working, but if you want a version supported until 2029, choose Office 2024.

Office 2021 still suits buyers who need to match an existing setup, for example an office where every PC runs the same version. For a new installation, Office 2024 gives you the longest remaining support period.

What are the system requirements for Office 2021 Standard?

You need a Windows 11 or Windows 10 PC with a 1.1 GHz dual-core processor, 4 GB of RAM and about 4 GB of free disk space. Office 2021 Standard doesn't run on macOS; Mac users need a Mac edition of Office.

Component	Minimum requirement
Operating system	Windows 11 or Windows 10 (and supported Windows Server versions)
Processor	1.1 GHz or faster, 2 cores
Memory (RAM)	4 GB
Storage	4 GB of free disk space
Display	1280 × 768 resolution
Internet	Needed for installation and activation

How do I install and activate Office 2021 Standard?

On each computer, install Office from the link in your order email and activate it with your licence key. For a few PCs, enter the key in Word; for many, IT staff can activate from the command line.

1. On each PC, uninstall older Office or Microsoft 365 versions from Settings → Apps.
2. Install Office 2021 Standard using the download link in your order email.
3. Open Word and enter the key when asked, or go to File → Account → Change Product Key.
4. To activate from the command line instead, open Command Prompt as administrator and run cscript "C:\Program Files\Microsoft Office\Office16\ospp.vbs" /inpkey:XXXXX-XXXXX-XXXXX-XXXXX-XXXXX, then the same command with /act (use "Program Files (x86)" for 32-bit Office).
5. Confirm activation with ospp.vbs /dstatus or under File → Account.

The most common problem we see is a different Office edition already on the PC, such as a preinstalled Microsoft 365 or Home & Business copy. Your key only activates Office 2021 Standard, so remove other editions and install the one from your order email.

Frequently asked questions

How many PCs does this licence cover?

It covers the number of PCs you choose when you order, anywhere from 5 to 50. Each of those computers can run Office 2021 Standard. If you later need Office on more PCs than you licensed, you need an additional licence for the extra computers.

Do all the PCs have to run the same edition?

Yes. Your key activates Office 2021 Standard only, so every computer covered by the licence needs that same edition installed. A Standard key won't activate Professional Plus, and a Professional Plus key won't activate Standard.

Does Office 2021 Standard include Access?

No. Access is only included in Office 2021 Professional Plus. Standard gives you Word, Excel, PowerPoint, Outlook, OneNote and Publisher. If you need to create or open Access databases (.accdb files), choose Professional Plus instead.

Is Office 2021 Standard a one-time purchase?

Yes. You pay once, with no subscription, and the apps keep working. Keep in mind that Microsoft's end-of-support date for Office 2021 is 13 October 2026. From that date, it gets no further security updates, so Office 2024 is the better choice for long-term use.
