  • PST: C:\Users\<username>\Documents\Outlook Files\
  • OST: C:\Users\<username>\AppData\Local\Microsoft\Outlook\

1.4.2 Check System Requirements

Ensure your system meets current Outlook requirements and verify that your Windows installation is stable.

2. Quick Fixes: First Steps to Try

2.1 Method 1: Restart Your Computer and Outlook

Simple restarts resolve many temporary conflicts that prevent Outlook from starting. This method clears memory issues and resets system processes that might interfere with Outlook.

  1. Close all applications and restart your computer completely
  2. After restart, press Ctrl + Shift + Esc to open Task Manager
  3. Look for any Outlook.exe or OUTLOOK.EXE processes
  4. If found, select them and click End Task
  5. Try starting Outlook normally from the Start menu

End the hanging Outlook processes in Windows Task Manager if you cannot start Microsoft Outlook.

If Outlook starts successfully after this method, the issue was likely caused by background processes or temporary system conflicts.

2.2 Method 2: Run Outlook in Safe Mode

Safe Mode starts Outlook with minimal functionality, disabling add-ins and custom settings that might cause startup problems. This diagnostic method helps identify whether third-party components are causing the issue.

  1. Press Windows + R to open the Run dialog
  2. Type outlook /safe and press Enter
  3. Wait for Outlook to start in Safe Mode. The title bar will contain “(Safe Mode)”.
  4. Test basic functionality like viewing emails and folders
  5. If Outlook works in Safe Mode, the problem likely involves add-ins or custom settings. You can try to disable add-ins or tweak the settings to fix the problem.

Run Microsoft Outlook in Safe Mode if you cannot start Outlook normally.

Safe Mode disables COM add-ins, custom toolbars, and reading pane customizations. If you cannot start Microsoft Outlook even in Safe Mode, the issue is more fundamental and requires advanced troubleshooting methods.

2.3 Method 3: Reset Settings via Command Line Switches

Outlook’s command line switches can reset various settings that might prevent normal startup. These switches clear specific configurations without affecting your email data.

  1. Press Windows + R to open the Run dialog
  2. Try these switches one at a time:
    Command Usage
    Outlook /restore Restore to the profile and folders in the last success launch
    Outlook /resetnavpane Reset the Navigation Pane to fix UI-related issue
    Outlook /resetfolders Restore missing default folders
    Outlook /cleanviews Reset corrupted custom views
    Outlook /cleanprofile Eliminate invalid profile keys and regenerate default registry keys where suitable
    Outlook /cleanpst Launch Outlook with a new clean PST file. After that, you can try to open the original PST file in Outlook.
    Outlook /cleancategories Removes custom categories
    Outlook /cleanclientrules Removes client-side rules
    Outlook /cleanreminders Clears reminder settings
  3. If one switch resolves the issue, that setting was causing the startup problem.
  4. Close Outlook and start it again normally.

These switches are safe to use and don’t delete your emails or contacts. They only reset specific interface and behavior settings to their defaults.

2.4 Method 4: Disable Add-ins

Third-party add-ins frequently cause Outlook startup failures. Disabling these extensions can immediately resolve the error that you cannot start Microsoft Outlook.

  1. Launch Outlook in Safe Mode. If Outlook cannot start in Safe Mode, this method is not applicable.
  2. Go to File -> Options -> Add-ins
  3. In the Manage dropdown, select COM Add-ins
  4. Click Go to view all active add-ins
  5. Uncheck to disable all add-ins and click OK
  6. Restart Outlook normally to check if the error is fixed.
  7. If Outlook can start successfully, re-enable the add-ins one by one to find the one that causes the error.

Manage and disable add-ins in Outlook options.

Common problematic add-ins include antivirus email scanners, PDF converters, and older third-party tools. After identifying the problematic add-in, check for updates or contact the vendor for compatibility information.

2.5 Method 5: Check for Windows and Office Updates

Outdated software can cause compatibility issues that prevent Outlook from starting. Installing the latest updates often resolves these conflicts.

  1. Press Windows + I to open Settings
  2. Go to Update & SecurityWindows Update
  3. Click Check for updates and install any available updates
  4. Open any Office application, such as Word, and go to File -> Account
  5. Click Update Options -> Update Now
  6. Restart your computer after all updates are installed
  7. Try starting Outlook again

Update Microsoft Office in Word if Outlook won't start.

Office 365 users receive regular updates that fix bugs and improve compatibility. Standalone Office versions also receive important security and stability updates that can resolve startup issues.

3. Intermediate Solutions

3.1 Method 6: Check OST/PST File Path

Incorrect file paths can prevent Outlook from accessing your data files, causing you cannot start Microsoft Outlook. Network-stored data files can also cause startup problems when the network connection is slow or unavailable.

  1. Try one of these methods to access Mail settings:
    • Method A: Open Control Panel -> User Accounts -> Mail (Microsoft Outlook)
    • Method B: Press Windows + R, type appwiz.cpl, click OK, then look for Mail (Microsoft Outlook)
    • Method C: Press Windows + R, type mlcfg32.cpl, and press Enter
    • Method D: Search for Mail in Windows Search and select Mail (Microsoft Outlook)
  2. Once Mail settings open, click Show Profiles
  3. Select your profile and click Properties
  4. Click Data Files to view all configured data files
  5. Verify that all listed data files exist at their specified locations
  6. If any files show incorrect paths, click Settings and browse to the correct location
  7. If any files are stored on a network drive, move them to your local drive and adjust the path accordingly.
  8. Click OK to save changes and close all dialogs

Verify Outlook data file paths are correct in Mail settings.

3.2 Method 7: Check OST/PST File Size

Oversized data files can prevent Outlook from starting properly. Below are the default size limits for PST/OST files:

  • Outlook 2003 – 2007: 20GB.

If the file exceeds the default limits, you can increase the limits:

  1. Press Windows + R and type regedit
  2. Navigate to HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Outlook\PST
  3. Create new DWORD values for MaxLargeFileSize and WarnLargeFileSize
  4. Set both values to increase the size limits as needed.
  5. Start Outlook.
  6. If Outlook can start successfully, consider to archive some old emails or split your PST file, since large data files not only prevent startup but also slow down Outlook performance significantly.

Change the PST/OST file size limits in Windows Registry if Outlook won't open.

More detailed information can be found on the official Microsoft siteExternal Link.

3.3 Method 8: Repair OST and PST Files

Corrupted data files are also a common reason why you cannot start Microsoft Outlook or cannot open the Outlook window. You can confirm this by using the following two methods:

  1. Use Outlook /cleanpst to launch Outlook with a new, clean PST file. If Outlook launches successfully, the cause of the previous failure was likely corruption in the original PST file.
  2. Copy the suspicious PST file to another computer with a working Outlook. Then, try to open the PST file in Outlook. If Outlook cannot open the file, your file is corrupted.

Microsoft provides a built-in repair tool ScanPST (Inbox Repair Tool) to fix these files. Follow our comprehensive guide to use it effectively.

If ScanPST fails, you might consider a specialized third-party tool like DataNumen Outlook Repair, which can handle severe corruption cases.

  1. Close Microsoft Outlook and other applications that may modify your source PST file.
  2. Select the source Outlook file (.pst).
  3. Set the output fixed file name.
  4. Click the “Start Repair” button

After the repair process, DataNumen Outlook Repair will output a new error-free Outlook file.
Use DataNumen Outlook Repair to repair a corrupted Outlook PST file.

3.4 Method 9: Create a New Outlook Profile

Corrupted profiles frequently cause Outlook won’t start issues. Creating a fresh profile often resolves these problems immediately.

  1. Open Control Panel -> User Accounts -> Mail (Microsoft Outlook)
  2. Click Show Profiles
  3. Click Add to create a new profile
  4. Enter a name for the new profile and click OK
  5. Follow the setup wizard to configure your email accounts
  6. Set the new profile as default by selecting Always use this profile
  7. Start Outlook to test the new profile

Create a new profile if Outlook won't start.

New profiles start with fresh settings and configurations. You’ll need to reconfigure customizations, but your email data remains accessible once you add your accounts.

3.5 Method 10: Repair Microsoft Office Installation

Corrupted Office files can prevent Outlook from starting. Microsoft provides repair options that can fix these issues without losing your data or settings.

  6. Try starting Outlook again

Use System File Checker (SFC) to check the system files if you cannot open the Outlook window.

SFC scans all protected system files and replaces corrupted files with cached copies. This process requires administrator privileges and can resolve deep system issues affecting Outlook.

3.7 Method 12: Check Antivirus and Firewall Settings

Security software can interfere with Outlook startup by blocking necessary processes or scanning email files excessively.

  1. Open your antivirus software’s main interface
  2. Look for email protection or real-time scanning settings
  3. Temporarily disable email scanning features
  4. Add Outlook to your antivirus whitelist or exclusions
  5. Check Windows Firewall settings for Outlook blocking
  6. Try starting Outlook with reduced security scanning
  7. If successful, configure permanent exclusions for Outlook files and processes

Many antivirus programs include aggressive email protection that can conflict with Outlook’s normal operation. Finding the right balance between security and functionality is essential.
