How to fix error 0x80040154 in Microsoft Outlook

In Microsoft Outlook, it would be wrong to say that errors are uncommon. Users often find themselves afflicted with an issue that prevents them from doing what they hoped to within the Microsoft application. This particular error is one that relates to a problem within Outlook’s configuration, and is one that is, thankfully, fairly simple to resolve.

In order to resolve your 0x80040154 Microsoft Outlook issue, you will need to download the free Microsoft application, titled ‘Microsoft Support and Recovery Assistant’. From here, you will be able to scan your application for any issues and resolve them from there.

Now, as is the case with every blog post, do not worry if the above paragraph is not enough detail for you to work with. Not only will there be a step-by-step to guide you through the process, but there will also be a more thorough, more detailed breakdown of the entire message.

Step by step: How to fix error 0x80040154 in Microsoft Outlook

  • Go to the Microsoft website.
  • Search for, and download, the free application titled ‘Microsoft Support and Recovery Assistant’.
  • Once that is downloaded, open and go through the Setup Wizard.
  • After doing this, and agreeing to the Terms and Conditions you will be shown, click ‘Advanced Diagnostics’.
  • Here, click ‘Outlook’, and advance to the next screen.
  • You will be asked if the machine you are using is the one with the issue. Click ‘Yes’ and continue.
  • Enter your account credentials and click ‘Next’ to continue with the process.
  • Once your scan is underway, it will automatically seek out any issues within your computer.

As was aforementioned, even if the step-by-step doesn’t offer you enough detail on the matter, don’t worry. Now, we will take a deeper dive into the method.

Before completing any steps, though, you need to make sure Microsoft Outlook is running. It is important to note that you need to be on the desktop version of Outlook, as opposed to the browser version. It needs to be running as, without it, the recovery assistant just will not run.

First, you will want to download the Microsoft Support and Recovery Assistant. In order to do this, you simply need to navigate to the official Microsoft website, who offers a link for a quick and easy installation. Your best bet would be to search for the assistant in your desired search engine. After opening the page, you should be greeted with this:

Highlighted by the red box is the download option that you will need to click in order to install the assistant. After clicking that, you should be notified that its download has started. Upon its completion, click on your download subtab and you should see the program. Whilst that has been emboldened by the red box below, the yellow highlight serves to dictate to you where you should click in order to open the setup wizard.

Upon opening the setup wizard, you will be greeted with the standard sort of menu you would expect from such an installation.

Once the initial verifications have completed, progress through the wizard. You will encounter the terms and conditions of the product, which you will obviously need to accept to progress with the download.

Once you have completed the setup wizard, you will be greeted with a dashboard of all Microsoft applications that the assistant can, well, assist you with. Of all options there, you should look towards the ‘Advanced Diagnostics’ option and click that.

Clicking Advanced Diagnostics will bring you to a new menu, on which will be three options for you to choose from. Of these three choices, click ‘Outlook’.

After clicking Outlook, click ‘Next’ to advance to the next step.

Here, you will be met with a screen asking if the computer you’re currently using is the afflicted machine. Make sure you are, and make sure to click ‘Yes’ on this screen.

After clicking ‘Yes’, and then clicking ‘Next’ the assistant will run through a process of detecting problematic files. Don’t worry if this ends up taking a few minutes, that’s completely fine. Once the scan has been completed, you should be met with a menu detailing all issues within your computer.

Now, it seems fair to note that the issues in the above screenshot may differ slightly from the ones on your screen. It is entirely dependent on the issues within your computer. Regardless, simply click on the issue you wish to resolve, click ‘Next’, and the assistant will provide you with the means to solve your problem. From there, you will have successfully fixed the 0x80040154 error within your Microsoft Outlook!
