Fix Outlook Error Code 0x80040154
To remove this Error 0x80040154 in Outlook, use any one of the following methods.
- Open Outlook in Safe Mode and see.
- Disable any newly installed add-in.
- Check if Outlook is running in Compatibility mode.
- Re-register the inetcomm.dll file.

1] Open Outlook in Safe Mode and see
When Outlook is throwing the error, exit the application. Click it again while holding down the Ctrl key. When prompted to open Outlook in safe mode or not, hit the Yes button and run the program.
Now, try receiving new emails to see if the problem is fixed.
If Outlook can run in Safe Mode, then surely some addon or extension is creating issues.
2] Disable any newly installed add-in
In Outlook, COM add-ins and Outlook add-ins both perform actions that Outlook doesn’t provide. Since add-ins are separate programs, occasionally an Outlook COM add-in can encounter problems that slow down the rest of Outlook or throws an error such 0x80040154.
If you just installed a new add-in for Outlook and started experiencing problems thereafter, disable the add-in and check if it solves the problem for you. To do this, simply open Outlook and click the File > Options > Addins. Remove any recently added add-in.
3] Check if Outlook can run in Compatibility mode.
Go to the following location – C:\Program Files\Microsoft Office\Office <N>\outlook.exe.
Here <N> is the Office version number.
Here, right-click the file and choose Properties > Compatibility.
Now, uncheck “Run this program in compatibility with…” and check if Outlook is working.
4] Re-register the inetcomm.dll file.
If the ‘inetcomm.dll’ file has become unregistered, it may hamper the normal functioning of Outlook and throw error code 0x80040154. So, try re-registering the inetcomm.dll file in Windows. For this-
Open Run dialog box by pressing Windows + R.
Next, type the following command and hit the Enter key.
regsvr32 inetcomm.dll
This command will re-register the inetcomm.dll file.
5] Repair Office
If all methods fail to work, consider repairing the Office.
Open Run dialog box by pressing Windows + R.
Next, type the appwiz.cpl command and hit the Enter key.
This command will open the Programs and Features.
Right Click on Microsoft Office 365 and choose Change.
In the next window that appears, choose Online Repair and click on Repair.
One of these is sure to help you fix the Outlook error.
