Mail crashes when selecting Exchange address to compose email

[pwrobel]

This is an odd one. I have added an Exchange email account to Mail, and it has received email perfectly, downloading around 2,500 emails. When I compose a new email it defaults to my normal POP account, but when I select – immediately I select – the Exchange email account as the sender, Mail quits. Any ideas?

First I've heard of it. See if changing any of the Mail>Preferences>Accounts>"accountname">Mailbox Behaviors>Store draft messages on the server settings affects that behavior.
