Hello,
This is a forum about Dynamics 365 Business Central. Maybe you can redirect your question to a forum that does handle Exchange Server support. Also note that Exchange Server 2013 did reach end of life cycle. The suggestion is therefore to test if you do also receive this error with other Exchange Servers like smtp.office365.com?
Thanks.
