Solution 1Recommended

Evaluate the Upgrade and Verify Office 2021 License Legitimacy

Assess the benefits of upgrading to Office 2021 and ensure your purchased product key is valid before making the switch.

Microsoft Office 2013 has reached the end of its official support, meaning it no longer receives security updates. Upgrading to Office 2021 offers continued support on modern operating systems like Windows 11 and includes significant functional improvements, particularly in Outlook.

Keep in mind that Microsoft Office versions generally do not offer a direct 'upgrade path.' You will need to install Office 2021 as a completely separate product. Therefore, checking your license validity is a critical first step.

1
Check your Microsoft Services and Subscriptions

Log in to your Microsoft account online and navigate to the 'Services & subscriptions' page. A legitimate retail purchase of Office 2021 should appear listed here and be permanently tied to your account.

2
Beware of unauthorized volume licenses

If you purchased an unusually cheap 'Office Professional Plus' key online (for example, around $70), be cautious. These are often unauthorized volume licenses rather than consumer retail licenses, and Microsoft may deactivate them at any time.

3
Uninstall Office 2013 to prevent conflicts

Because there is no direct upgrade path, having both versions installed can cause conflicts (especially with Outlook profiles). Go to Control Panel > Programs and Features, select Microsoft Office 2013, and click 'Uninstall' before installing Office 2021.

4
Install Office 2021 from your account

Once the old version is removed, return to your 'Services & subscriptions' page, locate your Office 2021 license, and click 'Install' to download the official installer.

Evaluate the Upgrade and Verify Office 2021 License Legitimacy
Keep a Backup of Office 2013: If you are unsure about the legitimacy of your newly purchased Office 2021 key, retain your original Office 2013 installer and product key just in case you need to revert to it later.

Frequently Asked Questions

Will I lose my existing files if I upgrade to Office 2021?

No. Your personal documents, such as Word files and Excel spreadsheets, are stored safely on your local hard drive or cloud storage. Uninstalling Office 2013 will only remove the application itself, and Office 2021 will be able to open your existing files seamlessly.

Can I keep both Office 2013 and Office 2021 installed on the same computer?

While it is technically possible to have two different versions of Office installed simultaneously, it is highly discouraged. Doing so often leads to software conflicts, file association errors, and serious issues with Outlook data files. It is best to uninstall the older version.

Why is Microsoft Office 2013 no longer supported?

Microsoft follows a standard lifecycle policy for its software, typically offering a set number of years of mainstream and extended support. Office 2013 has reached its end of life, meaning Microsoft no longer provides technical assistance, bug fixes, or critical security updates for it.

How can I tell if my Office 2021 key is a volume license?

Volume licenses are typically meant for large organizations and are often branded as 'Office Professional Plus.' If you bought a standalone key online for a drastically reduced price and it does not link directly to your Microsoft account under 'Services & subscriptions,' it is likely an unauthorized volume license.
