Here's a workaround that calmed it down for me. In Edit > Preferences > Autocompletion, I deselected everything under my Exchange accounts, restarted Evolution, and now it doesn't go thrashing every time I send an email. It still goes ballistic when I switch to the Contacts tab, but at least email's working right again.
