Understand the Upgrade Paths and License Differences

Determine whether Microsoft 365 or Office 2024 is the correct choice to replace your Office 2021 installation.

Office Home 2021 is a perpetual license. This means it is a one-time purchase that does not receive feature upgrades to newer versions like Office 2024. While security updates may be provided for a period, you will not get new tools.

To acquire new features, you must choose a new licensing path. You can either purchase another one-time license for Office 2024 or transition to a Microsoft 365 subscription.

1
Evaluate Microsoft 365

Opt for this subscription if you want continuous feature updates, 1TB of OneDrive cloud storage, and the ability to install Office on multiple devices simultaneously.

2
Evaluate Office 2024

Choose this option if you prefer a traditional, one-time purchase. It provides classic apps for a single Mac but will not receive future major feature upgrades.

Frequently Asked Questions

Will I lose my Word and Excel documents if I uninstall Office 2021?

No. Your personal documents are stored independently from the application files. Uninstalling Microsoft Word, Excel, or PowerPoint from your Applications folder will not delete your files stored on your Mac's hard drive or in OneDrive.

Do I get a free upgrade from Office 2021 to Office 2024?

No. Office Home 2021 is a perpetual (one-time purchase) license. It does not include upgrade rights to future major versions. You will need to purchase Office 2024 or a Microsoft 365 subscription.

How do I transfer my files to Microsoft 365 on a Mac?

There is no manual transfer process needed. Because Microsoft 365 uses the same file formats (.docx, .xlsx, etc.), you just need to install the new software and open the files exactly where they are currently saved on your device.

Can I leave Office 2021 installed when installing Microsoft 365?

While it is technically possible in some scenarios, Microsoft highly recommends uninstalling older versions of Office before installing a new one to prevent software conflicts, license confusion, and performance issues.
