Frequently Asked Common Questions
Everything you need to know before you buy
Is this a genuine Microsoft Office license?
Yes. Atom Software is an Authorised Microsoft Partner. When you buy Microsoft Office from us, every license activates directly with Microsoft's servers using standard Microsoft activation. You get the same genuine product you'd get purchasing from Microsoft directly at a lower price.
What's the difference between Microsoft Office and Microsoft 365?
Microsoft Office (2024 or 2021) is a one-time purchase that you own forever. You pay once and use it for as long as you want, on the version you bought. Microsoft 365 is a subscription you pay monthly or yearly, and if you stop paying, you lose access. For most users, the one-time purchase is significantly cheaper over 2-3 years and doesn't require ongoing payments.
Should I buy Office 2024 or Office 2021?
Office 2024 is the latest version with Microsoft support until October 2029 and full compatibility with the newest macOS versions (Sequoia, Sonoma, Tahoe). Office 2021 is a budget option at about $20 less, with Microsoft support until October 2026 and limited support for newer macOS versions. For most buyers in 2026, we recommend Office 2024 for the longer support lifecycle and better Mac compatibility.
How quickly will I receive my license?
Your license key arrives by email within 30 minutes of completing payment. In exceptional cases it may take up to 24 hours. The email contains your product key, official Microsoft download link, and step-by-step installation instructions. If you haven't received your email within an hour, check your spam folder or contact our live chat support.
Can I install Microsoft Office on multiple computers?
Each license is valid for one device. You can transfer the license to a different device for example, if you get a new computer by deactivating it on the old device first. The license cannot run on two devices at the same time. If you need multiple licenses for a household or business, contact us for bulk pricing.
Does Microsoft Office work on Mac?
Yes. Both Office 2024 and Office 2021 have Mac versions. Office 2024 fully supports the latest macOS versions including Sequoia, Sonoma, and Tahoe. Office 2021 has more limited support for newer macOS versions it works on older macOS but may have compatibility issues with the very newest versions. If you have a recent Mac, we strongly recommend Office 2024.
What if my license doesn't activate?
Contact us via live chat, phone, or email immediately. We provide free installation and activation support for every license we sell. Our team will walk you through the activation process and resolve any issue this is included at no extra charge. In the rare event we cannot resolve the activation, we offer a full refund with no questions asked.
Do I need to renew my license or pay again later?
No. This is a one-time purchase with a lifetime license. You'll never be asked to pay again for the version you purchased. Microsoft may release newer versions in the future, but your existing license remains valid indefinitely for the version you bought. This is fundamentally different from Microsoft 365, which requires ongoing monthly or yearly subscription payments.
