Pre-fill in "To" field on a new message in OWA 2003
In OWA 2003, you can now create a message and fill
in an address on the To field with a single URL:
https://server/exchange/user/drafts/?cmd=new&mailtoaddr=user\@domain.com
To fill in multiple addresses:
https://server/exchange/user/drafts/?cmd=new&mailtoaddr=user\@domain.com;user2\@domain.com
OWA will then open up a compose note with the addresses
already resolved for you.
