Office Professional Plus 2019 – Genuine Lifetime Licence Key (Windows)

Microsoft Office Professional Plus 2019 as a one-time purchase: $24.99 for one Windows PC, $44.99 for three or $99.99 for five, no subscription, and the key never expires. It is the full 2019 suite with Word, Excel, PowerPoint, Outlook, OneNote, Access, Publisher and Skype for Business. One thing to know before you buy: Microsoft ended support for Office 2019 on 14 October 2025, so it still installs, activates and runs but no longer receives security updates. If you want a supported version, Office Professional Plus 2024 is $29.99 and supported until 9 October 2029. The key and download link arrive by email in about 60 seconds, and every key is covered by our 30-day refund promise.

What is Microsoft Office Professional Plus?

Microsoft Office Professional Plus is the most comprehensive edition of Office, designed for businesses and power users who need the full suite of productivity applications. Unlike Home & Business or Standard editions, Professional Plus includes Access (database management), Publisher (desktop publishing), and Skype for Business, making it the complete package for professional environments. The 2019 version is a perpetual license—you pay once and own it forever—with no monthly subscription required.

Professional Plus vs other Office editions

If you need Access or the full feature set, Professional Plus is the edition to choose. For more details on which Office version fits your needs, see our Microsoft Office collection.

What you get with Microsoft Office Professional Plus 2019

Who should still buy Office 2019 Professional Plus

Two groups of customers keep choosing this edition. The first needs Publisher, which Microsoft removed from Office 2024 entirely, or the Skype for Business client for a company that still runs its own Skype for Business Server (it does not connect to Teams or consumer Skype). The second runs older add-ins, macros or line-of-business tools written and tested against Office 2019 and wants exactly that build on a replacement or spare PC. For either case this is the cheapest genuine Microsoft Office 2019 licence we sell, and it is not a trial or a subscription.

If neither applies, buy Office Professional Plus 2024. The apps look and behave almost the same, every 2019 file opens without conversion, and security updates until 9 October 2029 cost $5 more. Our Office 2019 end-of-life guide explains what "out of support" means day to day and how risky it is for a PC that opens email attachments.

How installation and activation work

1. Pay, and the email arrives with your key and the download link.
2. Uninstall any older Office or Microsoft 365 first (Settings > Apps), then restart. Office 2019 will not install alongside another version.
3. Run the installer. It is Microsoft's Office Deployment Tool with a configuration for Professional Plus 2019, and it downloads Office from Microsoft's servers (about 3 GB).
4. Open Word, go to File > Account > Activate Product, and enter the key. If online activation is blocked, phone activation takes about five minutes.

The Office 2019 Professional Plus download and installation guide has the installer for each language, file checksums, screenshots of every step and the fix for each common error code.

Frequently asked questions

What is Microsoft Office Professional Plus used for?

Microsoft Office Professional Plus is designed for business and professional use, particularly when you need Access for database management or Publisher for desktop publishing. It's ideal for organizations that need the complete Office suite without a subscription.

Is MS Office 2019 still supported?

No. Microsoft support for every edition of Office 2019, including Professional Plus, ended on 14 October 2025. It keeps working and activating, but it is no longer patched.

What is the difference between Office Professional Plus and Standard?

Professional Plus includes Access (database software) which Standard does not have. Both include Word, Excel, PowerPoint, Outlook, Publisher, OneNote, and Skype for Business. If you need database management, choose Professional Plus.

Is this key genuine?

Yes. Every key activates directly with Microsoft's servers. If a key does not activate, we replace it or refund you in full within 30 days.

Does it include Publisher and Access?

What is the upgrade path from Office 2019?

Office Professional Plus 2024 ($29.99) is the supported, like-for-like replacement, with security updates until 9 October 2029. Office Professional Plus 2021 ($29.99) is the last version with Publisher, but its Microsoft support ended on 13 October 2026, so it is a Publisher bridge rather than a long-term choice.

Does it work on Windows 11?

Yes, it installs and activates on Windows 11, though Microsoft will not issue compatibility fixes now that support has ended.

Does it work on a Mac?

No, this is the Windows build. For Mac, see Office for Mac.
