Usually, this problem indicates damage to a PST file, which is a very important file, where all kinds of information are stored. The error is typical for all relatively new Windows versions: 7, 8, 8.1, and 10. However, the error is not critical or terrifying, which is good. This article will show how, without leaving the system and without resorting to the help of specialists, to solve and remove the Windows 10 error code 0x80040154.

But first, let us draw your attention to the reasons that indirectly or directly may lead to Outlook error code 0x80040154.

Reasons for Outlook error code 0x80040154

First of all, it is worth noting there may be a conflict between a freshly installed antivirus program and built-in Windows protection from Microsoft.

Other reasons include:

  • Infection or damage to a PST file by third-party malware.
  • Accidental deletion of important system files.
  • Incorrect or damaged profile.
  • Exceeding the PST file size limit.
  • A non-direct removal of the program. Undetermined “tails” can continue to work, but only if it is incorrect.
  • Improper add-ins.

These are the main and most common causes of the problem of error code 0x80040154. Now you can begin to fix the problem and save the information stored in the application.

Method 1. Run antivirus to get rid of 0x80040154 error code

Here you need to try all the options. First, update your antivirus and run a computer scan.

You need to be sure that there are no threats to your computer. After that, restart your computer and try starting Outlook. If this does not work, then temporarily disable the antivirus (how to do this is found on the official website of the manufacturer). This is necessary to make sure that the antivirus does not interfere with the application and is compatible with it. If nothing happened and the error continues to appear, then the antivirus has nothing to do with it.

Then proceed to the method described below.

Method 2. Disable add-ins to fix error code 0x80040154

Sometimes the included add-ins only harm the normal operation of the application.

And if you turn them off, nothing bad will happen, but the application can work as normal. To do this, simply open Outlook and simply click the File tab on the taskbar. After that select “Parameters”, then left-click on “Add-ins”. Deactivate all available add-ins and click Apply.

Then it is recommended that you restart your computer.

Now, code 0x80040154 should disappear. The application should be available for use.

Method 3. Launch in safe mode in Outlook

Starting Outlook in safe mode can be done through the command line.

Press Win + R or, through the START menu, select the “Run” command.

A window opens with a command line. In it, we enter the following command: “Outlook / safe” (the command is entered without quotes). Press Enter or click "OK" and run Outlook in safe mode.

You can safely work in the application.

And to start the application in normal mode, close Outlook and open it as usual.

Method 4. Create a new profile in Outlook

This method will help if you have a problem with the profile.

In this case, create a new one and transfer all the information from the old profile there. Therefore, you must have a backup of the PST file. If there is none and the PST file is currently unavailable, you have to restore it.

You can do this with special professional software: DiskInternals Outlook Recovery.

It will instantly do file recovery and stop your suffering.

Method 6. Reinstall Outlook to remove error code 0x80040154

Reinstalling will delete all the accumulated files; therefore, be sure to make a backup in advance or restore them using Outlook Recovery.

Now proceed to reinstall Outlook. Right-click Start and select Control Panel. Select the section titled "Programs and Features." In the list that appears, you need to find the Microsoft Outlook utility and click the "Delete" button on the top toolbar. Now you need to wait until the process is completed.
