Every time I try to launch Microsoft Office Outlook, it says ‘failed to launch’ and gives me an error. How do I fix this?

The ‘failed to launch’ error happens to be one of the most common issues faced by Microsoft Users. It can often get quite frustrating not to be able to access essential documents or respond to official emails when required.

Fortunately, there’s a way to fix this. We’ve curated a step-by-step guide to help you repair Microsoft office on your Windows computer or laptop.

Part 1: Understanding Reasons for Outlook Error ‘Failed to Launch’

Before we fix this launching error, it’s essential to understand what causes it. Here are a few reasons why it might happen:

  • A Network Issue

Let’s begin with the simplest of issues; the network issue. Your Microsoft Office may have trouble launching due to the internet connection being lost or faulty. The internet may have disconnected, which is why the software is unable to launch.

  • Permission Issues

When multiple users are there on a device, one might experience issues getting permission to access the app. First, check Microsoft office from other user profiles on the same device and review for the error to be sure of this.

  • Expired Subscription

Microsoft Office isn’t free. When you subscribe to Microsoft Office, you can choose between various plans depending on your requirements.

The subscription renews automatically every month unless you run into a problem. If the payment hasn't cleared, you might experience ‘failed to launch’ errors.

  • Corrupt Files

One of the most common causes of Microsoft Office failing to launch is corrupt documents themselves. Hence, whether you’re trying to open up a Word, PowerPoint, or PDF document, you might experience hindrances.

This can be one of the most upsetting reasons for most people since it loses essential information.

Part 2: How To Repair Microsoft Office Errors?

Once you’ve understood the causes of the error, here’s how you fix them:

1 Check Network Settings

Before you get to any other step, you have to ensure a secure and complete network connection on your computer. Doing so will ensure that a network issue isn’t what’s preventing access to the document.

To do so, you can try accessing any other website on the same device at that very moment. If the website doesn’t work, you can ensure the network has glitched. Try fixing that before accessing another Microsoft document.

2 Fix User Settings

If the error occurs on only one user profile while another on the same device works, you can fix this error in a straightforward step. Go to the admin settings on your computer or laptop and add the user to the local admin group.

This will grant them the same rights as the admin, ensuring they don’t experience any other Microsoft errors.

3 Renew Your Subscription

To continue accessing your Microsoft Office Apps without any restrictions, you’ll have to renew your subscription immediately. By logging onto Microsoft’s official website, you can update your payment settings.

If there’s an issue with your credit card, you might have to contact your bank and get the issue resolved as soon as possible so that the auto-renewal subscription may go through and you can enjoy using Microsoft Office again.
