Buying guide
Buy Office 2024 Professional Plus cheap: prices, legitimacy and what to watch for
The secondary market for Microsoft licences is legal, but confusing. This guide shows how the price of Office 2024 Professional Plus comes about, which 10 criteria make up a reputable dealer, and how activation actually works after purchase.
Quick answer
Office 2024 Professional Plus can be bought cheaply from specialised software dealers such as Karinex, who legally resell unused volume licences as secondary-market goods. At Karinex the licence currently costs 129.90 euros. This price is made possible by bulk-buying volume licences and the 2012 ECJ ruling (Case C-128/11), which expressly permits trading in used software within the EU. More important than the price alone is the dealer's legitimacy: look for a complete legal notice (Impressum), a proper invoice as proof of purchase, and reachable customer service.
What is Microsoft Office 2024 Professional Plus?
Office 2024 Professional Plus is the most comprehensive edition of the Office 2024 line-up and is offered as a perpetual licence for a one-time purchase, not as a subscription. It is an LTSC version (Long Term Servicing Channel) for Windows, developed for businesses, power users and organisations that prefer a local installation without a mandatory cloud connection.
The software is paid for once and used on one Windows PC for an unlimited time. Microsoft provides security updates for this version for several years, but does not deliver new feature updates: the program stays at the 2024 feature level, but in return is independent of ongoing subscription fees.
Which programs are included?
The Professional Plus edition includes the most complete package of the classic desktop applications for Windows.
| Application | Function |
|---|---|
| Word | Word processing for documents, letters and reports |
| Excel | Spreadsheets with dynamic arrays and new chart types |
| PowerPoint | Presentations with recording feature (Cameo integration) |
| Outlook | Email and calendar management with improved search |
| Access | Relational databases – exclusive to Professional Plus |
| Publisher | Desktop publishing for flyers and brochures |
| OneNote | Digital notebook with Office integration |
Note: Microsoft Teams is not included in the LTSC variant, but is available free of charge as a separate app. According to the Microsoft lifecycle, Publisher will be taken off sale during the course of 2026, but will remain locally functional on installations that have already been activated.

How much does Office 2024 Professional Plus cost?
Through Microsoft's direct sales channel, the Professional Plus edition is primarily intended for volume-licence customers and is not sold individually to private customers via the Microsoft Store. On the legal secondary market, by contrast, significantly lower prices arise because dealers buy larger volume-licence packages and resell individual keys. At Karinex, a licence for Office 2024 Professional Plus currently costs 129.90 euros including product key, download link and an invoice showing VAT.
A low price from a transparent, reputable dealer is not a warning sign, but the result of legal volume-licence trading. Caution is warranted instead with sellers lacking recognisable company details, without an invoice, or with vague information about activation – regardless of the specific price.

What to do if the product key doesn't work?
Check for typos
Copy the key exactly from the email, without spaces before or after it.
Uninstall old Office versions
A parallel-installed old version (e.g. Office 2019 or an expired Microsoft 365 trial) frequently prevents activation. Completely uninstall all old Office installations and restart your PC.
Ensure an internet connection
Online activation requires a stable internet connection at the moment the key is entered.
Contact the dealer
If the key is permanently rejected, contact the dealer's support. At Karinex you can reach customer service by email, WhatsApp or live chat, daily from 06:00 to 23:00 (German time). Reputable dealers check the key and, in case of a defect, provide a free replacement key.

What should you particularly watch out for when buying a cheap Office key?
A complete legal notice (Impressum), a proper invoice and reachable customer service. A low price alone is not a warning sign with a transparent dealer.
