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.
On a Mac, keep Office updated to version 16.83 or later, which needs macOS 12 Monterey or newer. Microsoft says older Office for Mac builds switched to a reduced functionality mode on 13 July 2026, in which documents can be viewed and printed but not edited or saved.
What are the system requirements for Office 2021 Standard for Mac?
You need a Mac with an Intel or Apple silicon processor running one of the three most recent versions of macOS, plus 4 GB of RAM and 10 GB of free disk space. When Apple releases a new macOS, Microsoft drops support for the oldest of the three.
| Component | Minimum requirement |
|---|---|
| Operating system | One of the three most recent macOS versions |
| Processor | Intel or Apple silicon |
| Memory (RAM) | 4 GB |
| Storage | 10 GB of free disk space |
| Display | 1280 × 768 resolution |
| Internet | Needed for installation and activation |

How do I install and activate Office 2021 Standard for Mac?
Download the Mac installer from the link in your order email, install it like any other Mac app, then activate Office with the key and steps in the email.
- If this Mac has had another Office version or a Microsoft 365 trial, remove its licence first with Microsoft's License Removal Tool.
- Download the Office 2021 Standard for Mac installer using the link in your order email.
- Open the downloaded .pkg file and follow the installer.
- Install the latest updates from Help → Check for Updates, so Office is on version 16.83 or later.
- Open Word and activate Office using the key and steps from your email.
- Create and save a test document to confirm Office is fully activated.
The most common problem we see on Macs is a leftover licence from an earlier Office version or a Microsoft 365 trial, which makes Office keep asking you to sign in or subscribe. Remove old licences with the License Removal Tool, then activate again.
