Hello,
i'm having a strange issue during the activation on email integration in a customer D365 Sales environment (on-line) using the default Exchange Online server profile.
There are 20 users in this environment, all of them are good exception for one which presents the subject error during the "Test & Enable Mailbox" phase.
The error detail:
ActivityId: 57e5f018-ce6b-4f06-ade8-fb8ce4dbec63
>Error : Newtonsoft.Json.JsonSerializationException: Error converting value {null} to type 'System.DateTimeOffset'. Path '[0].body.sentDateTime'. ---> System.ArgumentException: Could not cast or convert from {null} to System.DateTimeOffset.

This is happening just for this specific user and exclusively on the Incoming Sync method (which is Server-Side Synchronization), the other two options (outgoing and Appointments, Tasks and Contacts) are perfectly fine. The user has the same settings/configurations of other users on his O365 profile (its an online profile, not synced with onprem AD) so no differences in this.
I already opened a support ticket to D365/Power Platform support, but they bounced me back telling me to contact directly the Exchange product team because the integration error is on their end; unfortunately i'm apparently prevented in doing this because the admin.microsoft portal allows me to just open ticket to customer's partner (one of them is my company, lol).
Someone has experienced errors like this one or can give me advice on the fastest way to contact the Exchage support?
Thanks in advance.
