Questions, answered.

99% of orders deliver to your inbox in under 5 minutes — most arrive within 60 seconds. The license key, official Microsoft download link, and a one-page activation guide are all attached. If your email hasn't arrived after 30 minutes, our support team will personally chase it down.

We accept Visa, Mastercard, American Express, PayPal, Apple Pay, and Google Pay. All payments are PCI-DSS compliant and processed via Stripe — we never see or store your card details.

Yes. During checkout, enter your company name and VAT/Tax ID. Your order confirmation will be a tax-itemised PDF receipt suitable for VAT reclaim across the EU and UK.

No — we are a digital-only business. All licenses are delivered by email as 25-character activation keys. This is genuinely faster than physical media and lets us offer significantly lower prices.

For 1–10 licenses, just adjust the quantity in your cart. For 5+ licenses we recommend our volume programme — additional discounts apply, and we can issue a consolidated tax invoice.

Yes — every license sold by MMkeys is genuine and sourced through authorised distribution channels. Each key activates directly against Microsoft's own activation servers, meaning your install will report as fully licensed in Windows Update, Office, and the Microsoft Account portal.

Easiest path: install the software, open any Office app or open Settings → System → Activation in Windows, click Change product key, and paste your 25-character key. The activation guide we email you covers each scenario step-by-step. No phone activation required.

This is rare (under 0.5% of orders) but if it happens, reply to your order email with the error message you're seeing. We'll diagnose and either replace the key (typically within 4 hours) or refund you in full. We don't leave anyone stuck.

Yes. Your perpetual Office and Windows keys are not single-use; you can reinstall as many times as you like on the same hardware. If you change motherboards, contact us — we'll help you re-link the license to the new hardware.

Standard perpetual licenses (Office 2024, Windows 11) are valid for one PC. Microsoft 365 Family licenses cover up to 6 users on multiple devices each. Need a license for multiple devices? See our volume options.

30-day money-back guarantee on every order. If a key fails to activate or you change your mind, contact us within 30 days of purchase. We process refunds within 24 hours, back to your original payment method. No restocking fee, no questions about why.

If a license you bought from us ever deactivates — even years later — contact support and we'll replace it free of charge. This has happened to fewer than 0.1% of customers, but the lifetime support guarantee stands regardless.

Standard Microsoft EULAs do not permit transfer of perpetual OEM keys. Retail licenses can sometimes be transferred but the process varies — get in touch if you need help.

Email us before activating the key — we'll swap it for the correct version free of charge. If you've already activated, contact support and we'll work out the cleanest path forward.

Office 2024 is a one-time purchase — you pay once, use it forever, but won't get major version upgrades. Microsoft 365 is a subscription — pay yearly, always get the newest features, plus 1 TB of OneDrive storage per user. Office 2024 is better if you want lifetime use; 365 is better if you value cloud storage and continuous updates.

Office 2024 Home & Business works on both Windows and macOS (one license per device). Office 2024 Pro Plus is Windows-only — Macs would need Home & Business or Microsoft 365.

Office 2024: Windows 10 (build 19045+) or Windows 11; 4 GB RAM; 4 GB disk. Windows 11 Pro: 4 GB RAM, 64 GB storage, TPM 2.0, UEFI Secure Boot. Specific edition pages list the full requirements.

No — we sell Microsoft's direct-download licenses, which work the same as Mac App Store but install via the Microsoft installer. Same apps, same activation, slightly more flexibility around reinstalls.
