Microsoft Office error 0x426-0x0 is an error code that appears when one of the programs in the Office suite fails to start. This error is common in Outlook, but can affect other Office applications as well. Error 0x426-0x0 usually occurs when users try to launch Outlook, Excel, Word, or PowerPoint.
It usually takes time to fix this error because the built-in Office recovery feature often doesn’t complete the fixing process.
So if you can’t always rely on the recovery feature, let’s see what else you can do to get rid of the 0x426-0x0 error.

- A separate box will open. From there, use the Startup Type drop-down menu and select Automatic.
- Click the start button.

Now launch the Office application. It should be running.
End all Microsoft Office processes by clicking and running (SxS) using the Task Manager

- Right-click on the taskbar and use Task Manager.
- Click the “Processes” tab in the Task Manager.

- Quick Repair uses a standalone utility on your system to find and fix common problems. If that doesn’t solve the problem, run the online repair.
- Make sure you have a stable and reliable Internet connection before performing an online repair.
If your Microsoft Office is MSI-based, you will see a “Change installation” dialog box instead. If so, click “Restore.”
Once the process is complete, reboot your system and see if the error persists.
To use the control panel, do the following:
- Run the Run dialog box by pressing the Windows and R keyboard keys at the same time.
- When Run opens, type “Control Panel” (without the quotes) in the text box and press Enter.
