I have spin up a Dynamics 365 trial instance (Plan 1) along with Office E3 Enterprise license to enable email functionality in Dynamics 365 using trial mailbox and exchange online using server-side sync. With these licensing configurations, I am able to Approve, Test/Enable mailboxes for some dummy users.
Emails are also going out 'sent' from Dynamics 365 to any valid email address and if sent to the same person, i.e. 'To' & 'From' are same in an email then both sent and received emails are showing up in CRM.
However, incoming functionality of email is not working in Dynamics 365, be it sent from trial user's mailboxes (OWA) or any other mailbox. Does anybody have any idea, where it might be getting stuck?
In short: Outgoing email is working, but incoming email functionality is not working with Server Side Sync.
