  • Hi All, i am trying to change mailto option from GPO. Currently it is pointing to outlook but i want to change it to just open a chrome or gmail website.

    I tried edit the following registry but server is missing those registry files.

  • Hi Aka-ola,

    If we want to add 3rd party email application as the default mailto application, we can register it under HKEY_LOCAL_MACHINE\SOFTWARE\Clients\Mail:

    For example, to include a mail client program in the list of available programs, register your client programs in the following registry key:


    Define the client and the path to the program to be started by Internet Explorer:

    Key: HKLM\SOFTWARE\Clients\Mail\Your_Mail_Client_Name\shell\open\command

    Value: "C:\Program Files\Your Folder Name\YOUR_MAIL_CLIENT_NAME.EXE"

    I’m glad to be of help to you!
