Answer : How can I add a user and password to AD with a power shell script?

If you deselect Word as the default email editor you won't have this problem.
You can try closing Word and Outlook (completely, meaning not open in Background) and then try opening word, it should work properly.
Otherwise another workaround is to only send maximized email messages.
