InternetExplorerIntegrationLocalMhtFileAllowed

Allow local MHTML files to open automatically in Internet Explorer mode

Supported versions

  • On Windows since 107 or later

Description

This policy controls whether local mht or mhtml files launched from the command line can open automatically in Internet Explorer mode based on the file content without specifying the --ie-mode-file-url command line.

This setting works in conjunction with: InternetExplorerIntegrationLevel is set to 'IEMode' and InternetExplorerIntegrationLocalFileAllowed is enabled or not configured.

If you enable or don't configure this policy, local mht or mhtml files can launch in Microsoft Edge or Internet Explorer mode to best view the file.

If you disable this policy, local mht or mhtml files will launch in Microsoft Edge.

Note that if you use the --ie-mode-file-url command line argument for launching local mht or mhtml files, it takes precedence over how you configured this policy.
