How to Fix Outlook Stuck on Loading Profile or "Processing" ​

Estimated Time to Fix: 3 minutes

Applies to: Microsoft Outlook (Classic)
Article Type: Troubleshooting
Last Updated: 2026-07-20

Summary ​

This article guides you through fixing a common issue where Microsoft Outlook freezes or gets stuck on the blue splash screen indefinitely while displaying "Loading Profile" or "Processing".

Symptoms ​

  • You open Outlook, but it never gets past the blue rectangular loading screen.
  • The loading text says "Loading Profile", "Processing", or "Starting".
  • The main Outlook email window never appears.

Prerequisites ​

  • None required.

Instructions ​

1. Force Quit the Hidden Outlook Process ​

  1. Even if the splash screen is closed, a background process might be stuck.
  2. Press Ctrl + Shift + Esc to open the Task Manager.
  3. In the Processes tab, scroll down and look for Microsoft Outlook.
  4. Right-click Microsoft Outlook and select End task.
  5. Wait a few seconds, then try opening Outlook again.

2. Start Outlook in Safe Mode ​

  1. Ensure Outlook is completely closed.
  2. Press the Windows Key + R to open the Run dialog box.
  3. Type exactly: outlook.exe /safe (make sure there is a space before the slash).
  4. Press Enter.
  5. When prompted to choose a profile, click OK.
  6. If Outlook successfully opens in Safe Mode, the issue is likely a corrupted Add-in.
  7. Go to File > Options > Add-ins, click Go... next to "COM Add-ins", and uncheck all add-ins. Click OK, close Outlook, and reopen it normally.

3. Run the Navigation Pane Reset Command ​

  1. If Safe Mode didn't fix the problem, a corrupted navigation pane might be the cause.
  2. Press the Windows Key + R to open the Run dialog box.
  3. Type exactly: outlook.exe /resetnavpane (make sure there is a space before the slash).
  4. Press Enter. Outlook will attempt to reset your folder layout and open normally.

4. Verify Success ​

  1. Close Outlook completely, wait five seconds, and open it from your Start menu or taskbar. It will load past the blue splash screen within a few seconds.
