[Evolution] Change user name due to authentication issue

[Trey Sizemore <trey fastmail fm>]

There has been a change at my employer where I now have to enter my
full e-mail for the username with Exchange rather than just the 'name'
portion.  Now when I launch Evo, it locks up with an authentication
error and I cannot use the GUI to change the credentials.

Where can I change this without launching Evo?  I tried making changes
with gconf-editor for apps -> Evo -> mail and changing gconf.xml, but
it doesn't appear to work.

Cheers,
