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

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
