Best for: the lowest-cost way to put a complete Office suite on an older machine.

The trade-off, stated plainly.
Office 2016 still works normally; Microsoft stopped releasing updates for it on 14 October 2025. It still installs and runs, and the licence never expires. Choose it for an offline or secondary PC; for a main machine that is online, Office 2024 LTSC stays supported until 2029.

Light on old hardware.
Of everything we stock, Office 2016 asks the least of a PC. On a machine with a spinning hard drive or 4 GB of RAM it usually feels quicker than the newer releases, which is the main practical reason people still choose it.

Included: Word, Excel, PowerPoint, Outlook, OneNote, Access and Publisher. Activation is by phone and takes about two minutes through our Get CID page — there is no call to make.
