My Microsoft outlook is not receiving any new email messages.

Check the status bar at the bottom of classic Outlook first; if it says Working Offline, Disconnected, or Trying to connect, select Send/Receive → Work Offline, then select Send/Receive All Folders.^1^

Determine whether Outlook or the mailbox is affected

1. Open your email account in its web browser service:
   • For an Outlook.com/Hotmail account, use Outlook on the web.
   • For Gmail, Yahoo, or another provider, use that provider’s webmail.
2. Send yourself a test message from another account.
3. Check the result:
   • The message appears in webmail but not classic Outlook: the mailbox is receiving mail; continue with the Outlook-specific steps below.
   • The message does not appear in webmail: the issue is with the mailbox or provider rather than the Outlook desktop application. Check mailbox storage, Junk Email, filtering rules, and the provider’s service status, or contact the email provider.
4. Also check Outlook’s Junk Email folder and the Other tab if Focused Inbox is enabled.

If mail appears in webmail

1. Verify Internet access. Open a browser and confirm that websites load. Outlook cannot synchronize while the PC is offline.^2^
2. Update classic Outlook.
   • Open File → Office Account → Update Options → Update Now.
   • Restart Outlook after the update completes.^3^
3. Run the connectivity troubleshooter if Outlook remains connected but does not synchronize:
   • Open the Windows Get Help app.
   • Run the Classic Outlook connectivity troubleshooter and follow its recommendations.
   • This requires Windows 10 or later, must run on the affected PC, and applies only to classic Outlook.^4^
4. Create a fresh Outlook profile if the troubleshooter does not resolve it:
   • Close Outlook.
   • Open Windows Control Panel → User Accounts → Mail → Show Profiles.
   • Select Add, enter a profile name, and add your email account.
   • Select Prompt for a profile to be used.
   • Start Outlook and choose the new profile.
   • Wait for synchronization and test for new mail.^5^

Do not delete the old profile until the new one receives mail and all required folders are present. If the new profile works, return to Mail → Show Profiles and remove the old profile when no longer needed.

Account-specific checks

• Password recently changed: update the saved Outlook credentials when prompted; an outdated password can prevent synchronization.^1^
• POP or IMAP account: compare the incoming server, port, encryption, username, and password with the settings supplied by the email provider. Microsoft’s setup guidance specifically recommends checking POP/IMAP settings when new messages cannot be received.^2^
• Still failing in every profile: repair the Office installation, then contact Microsoft Support or the email provider if webmail also fails. Microsoft identifies application and profile repair as later steps after connection checks.^1^
