Comment 1 for bug 82151

Thank you for your bug. The removal from packages doesn't remove user datas, that's a design decision, there is no reason a package should modifiy your datas. The datas are to the user and that's to user to decide if he wants to keep them or clean them. The account configurations are stored to gconf (.gconf/apps/evolution). Did you activate the exchange plugin from the plugins list? Do you have any error on the command line if you run evolution from it?
