Outlook - Lightning Sync connection test error

I am in process of setting up Lightning Sync for Outlook and have successfully gone through the OAuth 2.0 for Microsoft Exchange option to connect Salesforce to our email server.  I have accepted and enabled access to the server. 

However, the connection test has this error message "We can't connect with your email server using the email address you provided." I've also tried another user's email and the same errror is coming up. 

ERROR - https://ibb.co/eZW9mx

Do  I need to log this as a case?  Thanks all!

Same question:  Outlook - Lightning Sync connection test error​: The issue was that it takes 24 hours for major integrations and also for setting up user configurations for outlook integration.  It worked fine the next day.
