shepherdmu From the screenshots it looks like you're not running version 1.17? If so, chances are it's because Microsoft have disabled basic authentication on your tenant. You can temporarily re-enable it following the steps at https://www.kraftkennedy.com/how-to-temporarily-re-enable-basic-authentication-in-exchange-online/ , but long term you'll need to update to version 1.17, with the OAuth2 plugin.
