This will force Evolution to reconnect to the service using the current settings. However this is not a complete solution. If the new settings now point to a completely different mail account, we leave behind cached messages and database tables from the previous account such that you end up with some weird hybrid of the previous account and current account. I guess for now the answer is "don't do that", but we should try to handle that more gracefully in the future -- more for architectural correctness than it being a common real world use case.
