How to Fix Outlook 2016 Crash on Windows 11: Step-by-Step Solutions

Outlook 2016 is a widely used email client, but it can sometimes crash unexpectedly on Windows 11. This can disrupt your workflow and cause frustration. Fortunately, there are straightforward ways to fix this issue.

In this guide, you’ll find simple and clear steps to help you resolve Outlook 2016 crashes. Each solution is explained in detail to ensure even beginners can follow along easily.

By following these instructions, you can get Outlook running smoothly again without needing advanced technical skills. Let’s start troubleshooting your Outlook 2016 crash on Windows 11.

Take your time with each step and test Outlook after completing them to see if the problem is solved.

Quick Note: Prerequisites and Initial Checks

Before diving into fixes, please ensure the following:

Windows 11 is updated: Go to Settings > Windows Update and install any pending updates. This helps keep your system stable.
Office 2016 is updated: Open any Office app, go to File > Account > Update Options > Update Now. Updates often fix bugs that cause crashes.
Close other programs: Running many apps can cause conflicts or use too much memory. Close unnecessary applications before opening Outlook.
Restart your computer: Sometimes a simple restart resolves temporary glitches affecting Outlook.

Step 1: Start Outlook in Safe Mode

Starting Outlook in Safe Mode disables add-ins and customizations that might cause crashes. This helps identify if add-ins are the problem.

Press Windows + R to open the Run dialog box.
Type outlook.exe /safe and press Enter.
If Outlook opens without crashing, the issue is likely caused by add-ins.

Why this step is important: Add-ins extend Outlook’s functionality but can sometimes conflict with the app or Windows updates, causing crashes.

Step 2: Disable Faulty Add-ins

If Outlook works fine in Safe Mode, you should disable problematic add-ins.

In Outlook, go to File > Options > Add-ins.
Look at the bottom of the window next to Manage: select COM Add-ins and click Go.
Uncheck all add-ins to disable them, then click OK.
Restart Outlook normally.
If Outlook works, enable add-ins one by one by repeating steps 1-3 and checking one add-in at a time. Restart Outlook each time to identify the problematic add-in.

Why this step is important: Disabling add-ins helps isolate which one causes instability, allowing you to keep Outlook stable while still using essential add-ins.

Step 3: Repair Outlook 2016 Installation

If add-ins are not the problem, your Office installation might be corrupted. Repairing it can fix missing or damaged files.

Press Windows + R, type appwiz.cpl, and press Enter to open Programs and Features.
Find Microsoft Office 2016 in the list and select it.
Click Change at the top of the list.
Choose Quick Repair and follow the prompts.
If the problem persists, repeat and choose Online Repair (this takes longer but is more thorough).

Why this step is important: Repairing Office fixes issues caused by corrupted program files that can lead to crashes.

Step 4: Create a New Outlook Profile

Sometimes, Outlook profiles become corrupted, causing crashes. Creating a new profile can resolve this.

Close Outlook completely.
Press Windows + R, type control mlcfg32.cpl, and press Enter to open Mail Setup.
Click Show Profiles.
Click Add to create a new profile. Name it something like “NewProfile”.
Follow the on-screen instructions to add your email account to the new profile.
Under When starting Microsoft Outlook, use this profile:, select Prompt for a profile to be used.
Open Outlook, select your new profile, and check if it still crashes.

Why this step is important: Profiles store your email settings and data. A corrupted profile can cause Outlook to crash or behave unpredictably.

Step 5: Check for Conflicts with Antivirus Software

Sometimes antivirus programs interfere with Outlook’s operation, causing crashes.

Temporarily disable your antivirus software following the instructions from the antivirus vendor.
Open Outlook and see if it crashes.
If Outlook works fine, add Outlook to the antivirus software’s exception or whitelist.
Remember to re-enable your antivirus after testing for security.

Why this step is important: Antivirus programs scan emails and files, but can sometimes block Outlook processes or files mistakenly.

Step 6: Update Windows and Drivers

Outdated system files or drivers can cause compatibility problems with Outlook.

Open Settings > Windows Update and install all available updates.
Update device drivers, especially for your graphics card and network adapter, from the manufacturer’s website or via Device Manager.

Why this step is important: Keeping your system and drivers updated ensures better compatibility and fewer crashes.

Advanced Option: Use Microsoft Support and Recovery Assistant

If basic steps don’t fix the crash, Microsoft offers a free tool called the Support and Recovery Assistant (SaRA) that can automatically diagnose and repair Outlook issues.

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