Office 2019 Professional Plus Key (Account-Bound)

What you get

After payment you receive a 25-character Office 2019 Professional Plus product key by email, instantly in most cases (a system delay can occasionally add 5–10 minutes). The email includes the link to Microsoft’s website and our step-by-step installation guide, and the key is also saved under My Account → Keys.

What “account-bound” means

You redeem this key once on Microsoft’s website, setup.office.com, and Office 2019 Professional Plus is then bound to your Microsoft account. It shows up under Services & subscriptions in your account, where you can download and install it again at any time. If you replace your computer, uninstall Office from the old PC and install it on the new one from your account.

That is the difference from our standard Office 2019 Professional Plus key, which is for one PC and costs less.

What’s in Office 2019 Professional Plus

• Word, Excel and PowerPoint for documents, spreadsheets and presentations
• Outlook for email, calendar and contacts
• OneNote for notes
• Access for databases
• Publisher for flyers, brochures and newsletters

Office 2019 support status

Microsoft ended support for Office 2019 on 14 October 2025. It still installs, activates and works, but Microsoft no longer releases security updates for it. The account-bound version of Office 2021 is Office 2021 Professional Plus (Account-Bound).

Is it genuine? Why is it cheaper than Microsoft’s price?

Yes. It’s a genuine Microsoft key that you redeem and activate on Microsoft’s own website. We buy unused keys from companies that purchase Microsoft licenses in large batches and pass the lower price on to you.

How to install and activate

1. Uninstall any other version of Office on the PC, including trial versions.
2. Go to setup.office.com, select Get Started and sign in with your Microsoft account (or create one for free).
3. Enter your product key, choose your language and select Redeem.
4. Download Office from your account and run the installer.
5. Open Word and sign in with the same Microsoft account. Office activates online.
