Stop Outlook 2007 from hijacking mailto: links in Firefox

[Person]

Hi - I'm using Outlook 2007 on Win XP Pro as a
calendaring/collaborating app. I am not using it for sending and
receiving mail - I'm using Thunderbird for that.

When I click on mailto: links in Firefox (the only browser I use),
Outlook insists on opening a message window to handle them.

I have gone to Folder Options in Win XP and changed the registered
mailto: handler to Thunderbird twice and both times Outlook has
(after rebooting) changed those settings by registering itself as
the mailto: handler.

How can I stop Outlook from hijacking my settings?

Thanks very much.

 

[Cheers]

Try this:

Start Internet Explorer

Go to Menu Item Tools - Internet Options - Programs tab

Change the E-Mail selection to Thunderbird
