Microsoft Office 2021 Professional Plus for Windows

Microsoft Office 2021 Professional Plus for Windows is a one-time-purchase suite for Windows 10 and 11 that includes Word, Excel, PowerPoint, Outlook, OneNote, Access and Publisher. license4u.co delivers the licence key by email, and there is no subscription.

The Publisher question

Office 2021 is the last Professional Plus release that ships Publisher. Microsoft dropped it from the 2024 suite, so anyone who produces flyers, brochures or print layouts in Publisher should choose 2021 rather than 2024. That single difference decides the purchase for many small businesses and schools.

What is included

• Word 2021 with Focus mode and improved dark mode.
• Excel 2021 with XLOOKUP, dynamic arrays and LET.
• PowerPoint 2021 with slide show recording and narration.
• Outlook 2021 with instant search and built-in translation.
• OneNote, Access 2021 and Publisher 2021.

Frequently asked questions

Will Office 2021 stop opening files after October 2026?

No. The software continues to run and open files. What ends is Microsoft's security patching and technical support for this version.

How is Office 2021 different from Office 2019?

Same app line-up, but 2021 adds XLOOKUP, dynamic arrays and LET in Excel plus interface and performance improvements. Office 2019 Professional Plus is the lower-cost option if those do not matter to you.

Does this include OneDrive storage or Teams?

No. Cloud extras belong to Microsoft 365 subscriptions, not to perpetual Office licences.
