Office 2016 Professional Plus 5-PC Key

What you get

After payment you receive one 25-character Office 2016 Professional Plus product key by email, and that key activates Office on five PCs. Delivery is instant in most cases (a system delay can occasionally add 5–10 minutes). The email includes the download link and our step-by-step installation guide, and the key is also saved under My Account → Keys.

Who it’s for

The 5-PC key is the lowest-cost way to put the full Office on several Windows computers, for example in a small office or a family. You get the same Office 2016 Professional Plus as with the single-PC key, with one key to keep track of.

What’s in Office 2016 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 2016 support status

Microsoft ended support for Office 2016 on 14 October 2025. It still installs, activates and works, but Microsoft no longer releases security updates for it. For newer versions on several PCs, see Office 2019 Professional Plus (5 PCs) or Office 2021 Professional Plus (5 PCs).

License and activation

This is one Office 2016 Professional Plus key with five activations. You install Office 2016 Professional Plus from Microsoft on each PC and activate it online with the same key. Each activation stays with the PC it was used on.

Is it genuine? Why is it so cheap?

Yes. It’s a genuine Microsoft key that activates on Microsoft’s own servers. 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 on each PC

1. Uninstall any other version of Office on the PC, including trial versions.
2. Download Office 2016 Professional Plus with the link in your email and run the installer.
3. Open Word. When the activation wizard appears, enter your key and choose “I want to activate the software over the Internet”.
4. Repeat on the next PC with the same key, up to five PCs.

Tip: keep a list of the PCs you’ve activated. The full guide: Office 2016 installation and activation guide.

• “This product key can’t be used”: check that you typed the key exactly as in the email and that no other Office version is installed on that PC.
