How to Install Office 2024 When Office 2021 is Already Installed
Question details
The user needs to install Microsoft Office 2024 on a system running Office 2021, which requires removing the older version while preserving Outlook email data.
- Product
- Microsoft Office
- Device & OS
- Windows 11
- Scenario
- Upgrading to a newer Microsoft Office version without losing existing email configurations or local documents.
- Observed behavior
- The Office 2024 installer requires the removal of incompatible Office 2021 installations before the new setup can successfully proceed.
Ensure you locate and back up your Outlook .pst or .ost data files, and verify that you have your Office 2024 product key or associated Microsoft account credentials ready before proceeding.
Uninstall Office 2021 via Windows Settings
The standard and most reliable method for individual users to remove the older suite before upgrading.
Windows 11 provides a built-in uninstaller that safely removes the Office 2021 application files without deleting your personal documents or Outlook data files. However, a manual backup is always recommended.
Open Outlook 2021, go to File > Open & Export > Import/Export, and choose 'Export to a file'. Select 'Outlook Data File (.pst)' to safely back up your emails and contacts.
Click the Windows Start menu, select Settings (the gear icon), navigate to 'Apps' on the left sidebar, and click on 'Installed apps'.
Scroll down or search for 'Microsoft Office 2021'. Click the three-dot menu icon next to it, select 'Uninstall', and follow the on-screen prompts to remove the software.
Restart your computer. Run your Office 2024 setup file, sign in with your Microsoft account, and wait for the installation to finish. Open Outlook to import your previously saved data.
Use the Office Deployment Tool (For Enterprise)
Best for IT administrators upgrading multiple network systems to Office LTSC 2024.

Frequently Asked Questions
Can I keep both Office 2021 and Office 2024 installed at the same time?
No, it is highly recommended to remove older versions of Office before installing a new one. Running multiple versions side-by-side often causes file association errors, licensing conflicts, and performance issues.
Will uninstalling Office 2021 delete my Outlook emails and contacts?
Uninstalling the Office application suite does not delete your Outlook data files (.pst or .ost). However, manually backing up your Outlook data via the Export tool before uninstalling is strongly advised to prevent accidental data loss.
Do I need to purchase a new product key for Office 2024?
Yes, unlike Microsoft 365 which is subscription-based and updates automatically, Office 2021 and Office 2024 are standalone perpetual licenses. You will need a new, valid product key to activate Office 2024.
