Microsoft Office 2021 Pro Key Resellers – Understanding the Legitimacy and Risks Involved

Microsoft Office 2021 Pro Key Resellers – Understanding the Legitimacy and Risks Involved

Microsoft Office suites are an essential productivity tool for most businesses. These suites come with programs that support data resource management, content publishing, and email communication.

Some cheap keys are OEM versions that came bundled with computers or laptops. These may be legitimate, but can also be cracked.

Others are resold MSDN keys, used by developers to write software. They can be legit, but they won’t work in the long term.


The price tag on Microsoft Office can be prohibitive for many people, but it doesn’t have to break the bank. If you can find a deal, or even use a free version, you can save yourself a lot of money. There are also many gray market websites that sell legitimate Microsoft product keys at a fraction of the cost. These sites are often staffed by professionals with extensive knowledge of Microsoft products and are backed by a money back guarantee.

However, there are some things to be aware of when buying cheap Office keys. For one, these keys may not work in the long term. They are likely OEM versions that originally came bundled with PCs and were later wiped and sold. Alternatively, they may be cracks that use manufacturer’s ID codes to fool the activation process.

Finally, it’s important to note that purchasing a perpetual license for Office 2021 will not get you regular software updates. This is because it’s a different product from the subscription-based Microsoft 365, which is constantly upgraded.

So if you want to ensure that your copy of Office is always the latest and greatest, be sure to buy it from a reputable reseller like Mr Key Shop. They offer a full money-back guarantee, secure payment methods, and English-speaking customer service. You can even purchase a key for multiple copies of Office, which is perfect for larger teams.


There are some real risks to purchasing Microsoft Office 2021 Pro Key from a reseller. One of the main ones is that you could end up with a fake or non-working product key. This is a problem that many people experience and it can be very frustrating. Another risk is that you may get ripped off by the seller. The product keys sold by these sellers usually come from volume licensing or the educational market, so they are not necessarily legitimate. Some of them also have geographic restrictions and can only be used in certain regions.

These keys will also be subject to telemetry data collection and use. Microsoft treats this information as ‘diagnostic data’, which is separate from the categories of personal data and content that are protected by ePrivacy legislation. In the case of Office, this data is gathered only when users choose to use a discretionary Connected Service such as online spelling or translation.

Another risk of buying Microsoft Office 2021 from a reseller is that you won’t receive regular updates like those offered to Microsoft 365 subscribers. That isn’t a big deal for most people, but it is a factor to consider. If you want to stay up-to-date with the latest features, you’ll have to buy the suite again at some point in the future.


Buying Microsoft Office keys from gray market websites can be risky. Often, these sites are fraudulent and will not offer you any sort of refund or support. Some of these websites even require you to call a number to activate the software, which is against Microsoft’s terms of service.

While it is possible to find a Microsoft Office 2021 Pro Key at a discount from one of these sites, the product will likely not work as intended. This is because Microsoft checks your product keys after you install the software, and if the key isn’t valid, it will not activate. This is why it’s important to purchase your Microsoft Office suite from a reputable seller.

Another issue with these gray market sites is that they can be a goldmine for thieves. Some criminals steal credit or debit card information, buy Microsoft Office keys from gray market websites, and then sell them for a profit. Some of these websites are also plastered with trust seals, making it easy for thieves to fool unsuspecting consumers.

If you are looking for a legitimate way to buy Microsoft Office, try purchasing it from the Microsoft Store. It is much cheaper than buying a Microsoft 365 subscription, and it will give you the same features as the subscription version. This includes access to the classic suite of productivity apps, such as Word and Excel, as well as new co-authoring features, inking tools, data functions, and translation capabilities.


Microsoft office suites can be a significant investment, and the price can be a deterrent to many people. However, there are ways to save money on the software without compromising quality. For example, you can buy an OEM key from a gray market seller for a fraction of the retail price. These keys come from companies that bought more licenses than they needed and are then selling the extras.

Unlike licensed Microsoft Office suites purchased directly from Microsoft, OEM keys do not stay linked to your account and can be used on multiple computers. These keys are typically sold as a bulk package by manufacturers or retailers, and can also be found online. They can be used on Windows 10 and Mac OS computers. These keys are usually for the Home and Student version of Office, which includes Word, Excel, and PowerPoint.

Although these keys are considered legitimate by Microsoft, there are concerns about their reliability. Some users have reported that their keys stopped working after a certain period of time, or did not work at all. Others have even been deactivated months after installation.

Another concern with these keys is the risk of getting a virus or malware. Unlike licensed Microsoft products, these keys do not come with a guarantee, so it is important to research the seller before making a purchase.
