Have you ever tried to open links in Microsoft Outlook and receive an error that says Operation has been cancelled due to permissions error? Well, this permission error in Outlook is often due to a Chrome bug and the default browser.

The quickest and safest fix I have seen so far is to open up an Administrator command prompt and run the following command then reboot the computer and try opening the links again in the Outlook program and avoid editing the registry directly.

REG ADD HKEY_CURRENT_USER\Software\Classes\.htm /ve /d htmlfile /f
REG ADD HKEY_CURRENT_USER\Software\Classes\.html /ve /d htmlfile /f
REG ADD HKEY_CURRENT_USER\Software\Classes\.shtml /ve /d htmlfile /f
REG ADD HKEY_CURRENT_USER\Software\Classes\.xht /ve /d htmlfile /f
REG ADD HKEY_CURRENT_USER\Software\Classes\.xhtml /ve /d htmlfile /f

To make this simple for multiple computers with the same issues, copy and paste the commands into a batch file (with pause as the last command) and execute it from Administrator command prompt or by clicking on the file from Windows Explorer.
