The company that I work for is nice enough to let me use Linux for work, but they use Outlook. I've been using Outlook Web Access (OWA) as my mail client, which is more or less acceptable.

The only problem is that whenever I click on a mailto link or use the "Send Link" menu option in firefox, I'm prompted to use evolution. Since connecting to an exchange server through evolution seems to be sketchy at best, I would like to set OWA as my default mail client.

I'm using Firefox 3.6.13

Here's what I've found so far:

Default mail client can be found at

Edit Menu -> 
   Preferences -> 
      Applications Tab ->
         mailto

When I click on the drop down menu, one of the options is "Application Details"

This shows two options by default:

Google Yahoo! Mail

Each of these shows how to launch that service.

For Gmail:

https://mail.google.com/mail/?extsrc=mailto&url=%s

For Yahoo!:

http://compose.mail.yahoo.com/?To=%s

I presume that Outlook Web Access has something similar. Based on the googling that I've done so far, I think that this should look something like this:

https://<server name>/owa/?cmd=compose...

A little experimentation on my part shows that the following will compose a message:

https://<email server>/owa/?ae=Item&a=New&t=IPM.Note

but I still don't know how to specify recipient, subject or body of the email to be composed...

What I want to know is

a) does anyone know the URL parameters to compose a mailto in Outlook Web Access, including subject, recipient and body?

else

b) can someone give me a decent pointer for where to get this information?
