This bug is widespread in Outlook, but it can affect other Office programs as well. The 0x426-0x0 error usually occurs when users try to start Outlook, Excel, Word, or PowerPoint.

Fixing this error is generally time consuming, as Office's built-in fix attribute often does not complete the repair procedure.

How to resolve Microsoft Office error 0x426-0x0

1. Repair Office

Once you've completed all of that, launch the debatable Office program again and check to see if the 0x426-0x0 error persists.

3. Set Microsoft Click-to-Run to Automatic
