OWA 2010 - MAILTO LInks

Question

I made this work years ago in Windows XP creating a program in the registry that opened a internet explorer window pointing to the OWA URL parameters top create a new message.
In Windows 7/8 I haven't found a way to configure a entry in "Default Programs". Tried copying the registry keys created for Google Chrome MAILTO but no matter how much of it I pillaged and pointed to IEXPLORE.EXE, I couldn't get it to show up
in Default Programs.  So now I'm trying to chase down another way.
A typical mailto link looks like this:
mailto:[email protected]?Subject=Hello%20again
Outlook Web Access expects a link such as this:
https://mail.server.com/owa/?ae=Item&a=New&t=IPM.Note&to=[email protected]&subject=Hello%20again&body=Body%20Text
I'm trying to find a script or utility that I can register as a program in "Default Programs" for the MAILTO protocol.  If I can do this, maybe I can have it parse the MAILTO link and produce a OWA link call to IEXPLORE.EXE
There's no place like 127.0.0.1

Answer 1

Thanks, unfortunately that is the same solution I was using in Windows XP, and was one of the first things I tried.
The only thing I've had any luck with is this VBS script.  And only if there has never been any other MAILTO registered with the machine.  Even installing installing then uninstalling Outlook or Chrome isn't enough prevent it from ever working
again.
strURL = "https://name.exchange.com/owa"
If strURL <> "" Then
Set objWSHShell = WScript.CreateObject("WScript.Shell")
With objWSHShell
.RegWrite "HKLM\SOFTWARE\Clients\Mail\OWA\", _
"Outlook Web Access", "REG_SZ"
.RegWrite "HKLM\SOFTWARE\Clients\Mail\OWA\Protocols\mailto\", _
"URL:MailTo Protocol", "REG_SZ"
.RegWrite "HKLM\SOFTWARE\Clients\Mail\OWA\Protocols\mailto\URL Protocol", _
"", "REG_SZ"
.RegWrite "HKLM\SOFTWARE\Clients\Mail\OWA\Protocols\mailto\EditFlags", _
&H00000002, "REG_BINARY"
.RegWrite "HKLM\SOFTWARE\Clients\Mail\OWA\Protocols\mailto\DefaultIcon\", _
"%ProgramFiles%\Outlook Express\msimn.exe,-2", "REG_EXPAND_SZ"
.RegWrite "HKLM\SOFTWARE\Clients\Mail\OWA\shell\open\command\", _
"""%ProgramFiles%\Internet Explorer\iexplore.exe"" ", "REG_EXPAND_SZ"
.RegWrite "HKLM\SOFTWARE\Clients\Mail\OWA\Protocols\mailto\shell\open\command\", _
"""%ProgramFiles%\Internet Explorer\iexplore.exe""" & _
" " & strURL & "/?ae=Item&t=IPM.Note&a=New&email=%1", "REG_EXPAND_SZ"
.RegWrite "HKLM\SOFTWARE\Classes\mailto\shell\open\command\", _
"""%ProgramFiles%\Internet Explorer\iexplore.exe""" & _
" " & strURL & "/?ae=Item&a=New&t=IPM.Note&email=%1", "REG_EXPAND_SZ"
End With
Set objWSHShell = Nothing
WScript.Echo "Registry entries successfully created. OWA Configured as Default Mail Client"
Else
WScript.Echo "No OWA URL set to the variable strURL"
End If
