Windows Live Mail shut down/start up problem

Windows Live Mail on Windows 10 - Every time I send emails out, and then close Live Mail, I think it is okay, until I try to open Live Mail again. I get the "sending mail" window showing that it is not connected to the server. But the emails are already sent and there are no emails in the outbox. The only way to get Live Mail to open properly again is the annoying and temporary fix of ending process in task manager. I have tried many fixes, but none have worked. So, bottom line -- I can send emails. But, I have to end the process in task manager to open Live Mail again.
