Can’t Start Microsoft Outlook? What To Do When Outlook Won’t Open

So, you’re ready to check your email or manage your calendar when the unthinkable happens: Microsoft Outlook will not open. Even though it may be stressful, this is a surprisingly common scenario for many Outlook users. If and when this does happen to you, it’s important to remember that Outlook not opening usually has nothing to do with anything you’ve done; it’s most often the result of an internal error.

But what should you do if you cannot open Outlook? Is there a quick fix when Outlook does not open? What are the best ways to troubleshoot the problem? Finally, where can you get expert help with Outlook if you can’t solve the issue on your own?

In today’s guide, we will answer all of these questions and more, but first, let’s take a look at some of the most common reasons why Outlook won’t open:

Why Microsoft Outlook Won’t Open

There are several reasons why Microsoft Outlook may not open on the first try. It’s important to note that some of the most common underlying causes of these issues include software errors, viruses, or even power outages. In any case, here are a few of the technical reasons why Outlook isn’t opening:

  • Corrupted Outlook Profile – If your profile is corrupted, Outlook may not be able to open.
  • Damaged Outlook Data File – A damaged data file will prevent Outlook from opening properly.
  • Add-Ins – Add-ins can sometimes cause issues with Outlook.
  • Outdated Outlook Version – If you have an outdated version of Outlook, it may not be compatible with your current operating system.
  • Windows Updates – Sometimes, a Windows update can interfere with Outlook and cause it to stop working.
  • Antivirus Software – Antivirus software can occasionally cause problems with Outlook.
  • Hardware Issues – If your computer has hardware issues, such as a failing hard drive, Outlook probably won’t be able to open.

How to Troubleshoot Microsoft Outlook Startup Issues

Identifying the underlying cause of the problem is the first step toward getting Outlook up and running again. Fortunately, the issue is often an easy fix that can be handled in a matter of minutes. However, if it is more complex, you may need to spend a bit more time and effort resolving the problem. Here are some steps you can take to troubleshoot Outlook failing to open:

Check For Updates

Make sure that you have the latest updates installed for Microsoft Office. To check for updates in Microsoft Outlook, follow these steps:

  1. In Microsoft Office, click on the “File” tab in the top left corner of the screen.
  2. Click on “Office Account” or “Account.”
  3. Click on “Update Options” or “Update Now.”
  4. Outlook will check for any available updates and automatically install them.
  5. Once the updates have been installed, restart Outlook.

Run Outlook in Safe Mode

Try running Outlook in safe mode to see if it opens without any issues. To do this, follow these steps:

  1. Press and hold the “Ctrl” key on your keyboard and then click on the Outlook icon.
  2. If prompted to start Outlook in safe mode, click “Yes.” If you’re not prompted, it means that no add-ins are currently causing issues.
  3. Once Outlook starts in safe mode, you’ll see a message in the title bar that says “Outlook Safe Mode.”
  4. When you’re finished with safe mode, close Outlook normally.

Note: If you’re using Windows 10, you can also start Outlook in safe mode from the Start menu. Press and hold the “Ctrl” key while you click on the Outlook icon in the Start menu, and then click “Yes” when prompted to start in safe mode.

Disable Add-ins

When you’re having trouble opening Microsoft Outlook, disabling add-ins can be a helpful way to troubleshoot the problem. You will need to do this in Safe Mode, so refer to the previous section to start Outlook this way. Once you’ve got it running, you can disable add-ins like this:

  1. In Outlook Safe Mode, click on “File” in the top left corner of the screen.
  2. Click on “Options” in the left-hand menu.
  3. Click on “Add-ins” in the left-hand menu.
  4. At the bottom of the screen, next to “Manage,” select “COM Add-ins” from the drop-down menu.
  5. Click “Go.”
  6. Uncheck the box next to any add-ins you want to disable.
  7. Click “OK.”
  8. Restart Outlook (not in Safe Mode). If it still won’t open, retry steps 1-7 using different add-ins.

Note: Some add-ins are essential for Outlook to function properly, so be cautious when disabling add-ins. If you’re not sure what an add-in does, it’s best to leave it enabled.

Create a New Outlook Profile

If your profile is corrupted, you may need to create a new one. To make a new profile, just follow these steps:

  1. Open the Control Panel on your computer.
  2. Click on “Mail” or “Mail (32-bit).”
  3. Click on “Show Profiles.”
  4. Select “Add.”
  5. Type a name for the new profile and follow the prompts to set it up.
  6. Once the new profile is set up, you can select it from the “Always use this profile” dropdown list.
  7. Click “OK” to close the window.
  8. Try to open Outlook with your new profile.

Note: Creating a new profile will not delete your existing Outlook data, such as emails, contacts, and calendars. However, you will need to set up your email accounts and other preferences again in the new profile. If you want to keep your old profile as a backup, you can choose to not delete it during the profile creation process.

Repair Your Outlook Data Files

If your Outlook data files are damaged, you will need to repair them. To repair data files, follow these steps:

  • Go to File > Account Settings.
  • Click the “Data Files” tab and then select the data file that you want to repair.
  • Click “Settings” and then click “Compact Now” to repair the file.

Note: If the above steps don’t resolve your issue, you may need to use the Inbox Repair tool (scanpst.exe) to repair your data file. This tool is included with Microsoft Outlook and can be found in the installation directory. It’s recommended to make a backup copy of your data file before using the Inbox Repair tool so that you don’t lose anything.

Reinstall Outlook

If none of the previous steps work, you may need to reinstall Outlook. Before doing this, make sure that you have a backup of your Outlook data files. You can uninstall and reinstall Outlook by following these steps:

  1. Open the Control Panel on your computer.
  2. Click on “Programs and Features” or “Add/Remove Programs.”
  3. Locate Microsoft Office or Microsoft Outlook in the list of installed programs.
  4. Click on it and select “Uninstall.”
  5. Follow the prompts to uninstall the program.
  6. Restart your computer.
  7. Sign in to your Microsoft account.
  8. Click on “Install Office.”
  9. Select “Install” under “Microsoft Outlook.”
  10. Follow the prompts to install Microsoft Outlook.
  11. Once the installation is complete, open Microsoft Outlook and set up your email accounts and other preferences.

Note: If you have a standalone version of Microsoft Outlook (not part of Microsoft Office), you will need to reinstall it using the installation media or download it from the Microsoft website.
