How to Uninstall Outlook on Windows 10: A Step-by-Step Guide

How Outlook is removed from Windows 10 depends on whether it was installed as part of Microsoft 365/Office or as a separate new Outlook app. Check the installed package before uninstalling.

  1. Open Settings > Apps > Apps & features.
  2. Find Outlook, Microsoft 365, or the relevant Office suite entry.
  3. If Outlook is a separate app and Uninstall is available, select it and uninstall normally.
  4. If classic Outlook is part of an Office suite, Microsoft’s supported installation options may require modifying or reinstalling the suite rather than removing only Outlook.
  5. Restart if requested and confirm other Office apps still work.

Back up local Outlook data

PST archives and other local-only data can contain mail, calendars, and contacts not stored on the server. Locate and back up anything important before changing Office.

Removing the app does not delete the mailbox

Microsoft 365, Outlook.com, Exchange, Gmail, and IMAP mail normally remain on their servers. Local POP/PST content needs more care.

Windows 10 status

Both Windows and Office support requirements evolve. Windows 10 ended standard support in 2025, so consider the OS lifecycle when troubleshooting current Outlook versions.

Classic Outlook profiles

If you are removing Outlook because a mail profile is broken, uninstalling the entire application may be unnecessary. Control Panel’s Mail settings can manage profiles for classic Outlook. Preserve PST files and understand which account data is server-based before deleting a profile.
