I have a number of applications (e.g. GoToMeeing) which open up an e-mail which is ready to write. However, they always open Outlook instead of the e-mail client that I use: Thunderbird.

Where is the config file / setting in Windows7 so applications open Thunderbird by default instead of Outlook?


Thunderbird is not in my "list of standard programs":

  • Click the Start Menu and select Default Programs from the right hand menu column.
  • From there, click Default Program again.
  • Highlight Thunderbird from the list that gets built and click Choose defaults for this program.
  • Finally, select the mail option from the list of actions and click Save.

If the program is not in the list of possible, try this:

  • Back up one screen to the Default programs page
  • Select Associate a file type or protocol with a program
  • Scroll to the very bottom of the list to the protocol section
  • Select the program you want to use or Browse to find Thunderbird.

I got that far, but Thundbird (or Outlook for that matter) is not in my list of standard programs (screenshot posted above in question). How can I add them to this list? – Edward Tanguay Aug 24 '11 at 8:19
I added instructions for adding programs to the list – uSlackr Aug 29 '11 at 14:08
