Veja abaixo como fazer o que você deseja usando o Google Chrome e o Gmail. Deve ser bastante evidente como adaptar o método para trabalhar com o IE8 e o hotmail.
Torne os links mailto: abertos no Gmail no navegador Google Chrome (Windows XP e Vista)
WIndows XP
In any windows explorer window (except desktop):
- Go to Tools > Folder Options > File Types
- Near the top of the list of filetypes, click on “URL:Mailto Protocol”
- Click on “Advanced”
- With “open” highlighted, click on “Edit”
Change the application to:
"C:\Pathto\chrome.exe" https://mail.google.com/mail?extsrc=mailto&url=%1
This should all be on one line with a space between the quotation mark after the path info and the https. My path was
C:\Documents and Settings\Brendan\Local Settings\Application Data\Google\Chrome\Application\chrome.exe
To find yours, just right click on a google Chrome shortcut (like the one in your start menu), go to “properties” and copy the “Target” field.
Windows Vista
- Open your registry editor (Type “regedit” at your start menu)
- Navigate to HKEY_CLASSES_ROOT\mailto\shell\open\command
Edit the (Default) command from whatever it is (right click and select modify) to:
"C:\Pathto\chrome.exe" https://mail.google.com/mail?extsrc=mailto&url=%1
In Vista, your path will be something like
C:\Users\Brendan\AppData\Local\Google\Chrome\Application\chrome.exe
with “Brendan” being your username.
