Microsoft 365 is stronger for multiple devices, OneDrive, collaboration and continuous updates. Office 2021 can still serve an existing installation, but its Microsoft support ends on October 13, 2026.

Office 2021: familiar, but near its support deadline
Office 2021 remains a familiar desktop suite, and the October deadline does not switch off a valid installation. The limitation is lifecycle: after October 13, 2026, Microsoft no longer provides security fixes, bug fixes, or technical support for that version. It is therefore difficult to recommend as a fresh long-term purchase when supported alternatives are available.
Office 2024: one-time purchase, current desktop apps
Office 2024 is designed for buyers who want classic Word, Excel, PowerPoint and other included apps on one PC or Mac without a recurring fee. You receive security and quality updates during its lifecycle, but the purchase does not include a free upgrade to the next major Office release or Microsoft 365 services.
View Microsoft Office 2024 Professional Plus and confirm the included apps, device count, and system requirements before ordering.
Microsoft 365: subscription with cloud and multi-device benefits
Microsoft 365 keeps supported apps current and adds connected services. Depending on the plan, benefits can include OneDrive storage, collaboration, and installation across several PCs, Macs, phones, or tablets. It is usually the better fit for households and people who move between devices.

Microsoft lifecycle versus DigiT World support
Microsoft decides when its software receives vendor updates. DigiT World separately provides eligible order delivery, activation guidance, and product-related customer assistance under our support terms. Microsoft's Office 2021 deadline does not mean DigiT World stops helping customers; it means we cannot supply the Microsoft security updates that end with that lifecycle.
Which one should you buy?
- Home PC with no subscription: Office 2024.
- Family using several devices: Microsoft 365 Family.
- Frequent collaboration and cloud files: Microsoft 365.
- Existing Office 2021 user: continue briefly if required, but plan a supported replacement before October 13.
- Business or regulated work: follow your organisation's security and licensing policy; supported software should be the default.
