Prerequisites for Office 2021 activation

Before going ahead with attempting to activate Office 2021 Professional Plus or other versions of the suite, you need to ensure you’ve crossed off a few things beforehand, which are essential prerequisites for Office 2021 activation. Firstly, ensure that your computer meets the minimum requirements to run all of the software in the suite that you’re interested in – make sure you do this before you buy so you don’t waste your money!

Can I Activate Office 2021 for free using the KMS client key?

The Key Management Services (KMS), formally known as the Microsoft Generic Volume License Key (GVLK), is a legit ‘activation service that allows organizations to activate systems within their own network’. This system can be abused in order to activate Office 2021 for free, however this is illegal and limits the ability of the user to access certain features that only legitimate copies of Office 2021 can access. Plus, free KMS emulators are potentially dangerous as they require administrator privileges to function, that means free access to any data or PC setting. And if you buy antivirus software, you won’t be able to use it because the KMS emulators also require the deactivation of the antivirus protection. If the downloaded KMS is designed to infect a PC, nothing will stop it.

Ultimately, when you can get such a good deal on this products, it’s just not worth the headache and the potential risks involved, and we strongly encourage you to pick up a legitimate copy,

Activate Office 2021 without Microsoft Account

There is no officially supported way to activate Office 2021 without a Microsoft Account. Every copy of Office must be linked to an individual Microsoft Account in order to register its authenticity.

Troubleshooting common Office 2021 activation issues

Sometimes, the road to activation can have a few bumps. If you encounter any issues during the Office 2021 activation, we advise that you follow the below steps in order:

Double-check your product key for errors. Make sure you have entered the digits/letters correctly, including any dashes.
Ensure your internet connection is stable. A disrupted connection may cause a problem in the online activation process.
Make sure you’re signed into the right account. It could be that the one you are signed into isn’t the same as the one you used to buy the Office activation key.
Check you don’t have multiple copies installed by mistake. The best way to do this is to open the Control Panel then go to Programs and Features and look through the list. Uninstall any duplicate of the application.
Restart the Office application or your machine.

Features Unlocked After Office 2021 Activation

Besides the user interface and visual design uplift across all its software, Office 2021 activation gives you access to the following new features for each of the included applications to enhance your working experience (note: these lists are not exhaustive):

A world-class Word: Word 2021 has better performance, stability and speed compared to the preceding 2019 iteration. New features include many things imported from Office 365, including co-authoring, smart citations, AI-powered advanced grammar checks, new data analysis tools, dark mode, Line Focus, and support for ODF 1.3 file format.
Excel‘s enhanced functionalities: This latest version of Excel comes with improved data visualization tools, co-authoring and a shared comments system, new functions like XLOOKUP, XMATCH, LET, and Dynamic arrays, increased calculation speeds, and once again ODF 1.3 file support.
Powered-up PowerPoint: New features include an improved Record Slide Show function, Replay/Rewind for in strokes, hex color input, improved element arranging, slide linking, and, as with the other applications, improved integrated Microsoft Search, and updated Draw tab, and ODF 1.3 support.
Outlook‘s optimized offerings: The new iteration brings with it a more organized inbox, more advanced security features, Instant Search, Translator, Ink functions allowing drawing and annotation on emails, hex color input, and improved stock media.

Office 2021 vs. Office 2019

Microsoft Office 2019 remains a solid productivity package that comes with all the same software applications as the later iteration, however it lacks the latest features pertaining to cloud integration, AI support, collaborative features, and the overall redesign of the user interface. As mentioned, Office 2021 has more advanced co-authoring functionality, better security, and cross-device compatibility and synchronisation, plus comes with full Microsoft Teams integration. If you don’t need all the latest tools but just a reliable, high-performance and functional productivity suite, buying an Office 2019 key can be the cheaper and effective option for you.

Office 2021 vs. Office 365

Office 365 is a subscription service that requires annual repayments. It does receive regular updates which may be attractive to you, but in a short time it will get much more expensive than a lifetime licence. The Microsoft Office 2021 key is a one-time purchase that (in theory at least) affords you a ‘lifetime licence’ meaning that you never had to renew it with additional payments. The reality is of course that Office 2021 will eventually reach a point where it is no longer compatible with future operating systems (i.e. future versions of Windows), so is unlikely to last your lifetime, though you could still get more than a decade out of it, which would be substantially cheaper than paying regular payments over this same amount of time.

Tips for a Smooth Office 2021 Experience

To make sure your experience with Microsoft Office 2021 goes as smoothly as possible, always remember the following:

Make sure that your system and operating system are compatible with this version of Microsoft Office. As mentioned above – always check the official system requirements.
Ensure that your download of the software AND the activation key are both genuine: the best way to ensure this is to make sure you only purchase from reputable vendors and that you steer clear of offers that sound too good to be true (genuine activations are straightforward and don’t require third-party tools).
Familiarise yourself with how best to set up the various software included within Office 2021, plus how to navigate their interfaces, by either watching or reading online tutorials. There are a great many free resources out there for people with varying degrees of expertise.

Conclusions

Office 2021 remains the most current and relevant software suite for the majority of users, particularly in the world of business, which includes those utilising the Windows operating system but also those operating MacOS. This version of Microsoft Office offers seamless functionality across a range of devices plus all the latest design improvements and connectivity functionality.

You can achieve great savings on this handy bit of kit by purchasing the software from reputable retailers like Mr Key Shop or Keycense, which provide the best deals for Microsoft Office.
