Fortunately, there are several simple steps you can take to fix this issue. This guide will walk you through each solution in a clear and easy-to-understand manner.

No advanced technical knowledge is needed to follow these instructions. Just take your time and follow along step-by-step for the best results.

Let’s begin by checking some quick prerequisites before diving into troubleshooting.

Quick Note: Prerequisites and Initial Checks

Ensure Outlook is fully closed: Before starting, make sure Outlook is not running in the background. You can check this in the Task Manager by pressing Ctrl + Shift + Esc and ending any Outlook-related processes.
Check for Windows Updates: Having the latest updates installed on Windows 11 can prevent compatibility issues. Go to Settings > Windows Update and install any pending updates.
Restart your computer: Sometimes, a simple restart can clear temporary glitches causing errors.
Backup your Outlook data: Just in case, back up your Outlook data files (.pst or .ost) to avoid any accidental data loss during troubleshooting.

Step 1: Start Outlook in Safe Mode

Starting Outlook in Safe Mode disables add-ins and customizations that might be causing the startup error. This helps to isolate the problem.

Press Win + R on your keyboard to open the Run dialog box.
Type outlook.exe /safe and hit Enter.
If Outlook opens successfully in Safe Mode, it means one of your add-ins is likely causing the error.
Go to File > Options > Add-ins in Outlook.
At the bottom, next to “Manage,” select COM Add-ins and click Go.
Uncheck all add-ins and click OK.
Restart Outlook normally and enable add-ins one by one to find the culprit.

Step 2: Repair Microsoft Office

Corrupted Office installation files can cause startup errors. Repairing Office can fix these files without affecting your data.

Press Win + I to open Settings.
Navigate to Apps > Installed apps.
Find Microsoft Office in the list and click the three dots next to it.
Select Modify.
Choose Quick Repair and click Repair. Wait for the process to finish.
If the problem persists, repeat the steps and select Online Repair for a more thorough fix.

Step 3: Create a New Outlook Profile

Sometimes, your Outlook profile may become corrupted, causing startup issues. Creating a new profile can resolve this.

Close Outlook completely.
Open Control Panel by typing Control Panel in the Start menu and selecting it.
Click on Mail (Microsoft Outlook).
Click Show Profiles.
Click Add to create a new profile and give it a name.
Follow the prompts to set up your email account in the new profile.
After setup, select Prompt for a profile to be used or set the new profile as default.
Open Outlook using the new profile to see if the error is resolved.

Step 4: Run Outlook as Administrator

Running Outlook with administrative privileges can resolve permission-related startup errors.

Right-click the Outlook shortcut or executable file.
Select Run as administrator.
If Outlook opens successfully, you can set it to always run as administrator by:

Right-clicking the shortcut and selecting Properties.
Going to the Compatibility tab.
Checking Run this program as an administrator.
Clicking Apply and OK.

Step 5: Update or Reinstall Outlook

Outdated or corrupted Outlook versions may cause errors. Keeping your app up-to-date or reinstalling it can fix such problems.

Open any Office app and go to File > Account > Update Options.
Select Update Now to check for and install updates.
If updating doesn’t help, uninstall Office from Settings > Apps > Installed apps.
Restart your PC.
Download and install Office from the official Microsoft website or your Office subscription portal.

Alternative Method: Use Microsoft Support and Recovery Assistant

Microsoft offers a free tool called Support and Recovery Assistant (SaRA) that can diagnose and fix many Office-related issues automatically.

Download the tool from the official Microsoft website.
Run the application and select Outlook.
Follow the on-screen instructions to detect and resolve problems.
