Authenticated Secure SMTP
Struggling to understand how to configure MS365 Business Standard (or Exchange Online Plan 1) for Authenticated Secure SMTP. This is for a third party vendor to securely send data to an email address inside my MS365 tenant.
With multiple ways of saying the same thing, getting overwhelmed with how to proceed.
Extract from vendor 'instructions':
Authenticated Secure SMTP: This provides a higher level of confidence to the customer as this method allows stronger data integrity since the connection is authenticated. The authentication process comes on top of the Secure SMTP TLS based communication. The authentication as well as the data payload is encrypted by the TLS protocol. This is a secure method and should address most security concerns.
Customer needs to update their account manager with the details of their mailbox email address and the corresponding authentication details (username and password).
Any pointers gratefully received!
Thank you.
