Emails are not received in a Dynamics 365 mailbox and you see a warning alert like the following in a user's mailbox record:
"An unknown error occurred while receiving email through the mailbox "[Mailbox Name]". The owner of the associated email server profile [Profile Name] has been notified. The system will try to receive email again later.
Email Server Error Code: Exchange server returned UnknownIncomingEmailIntegrationError -2147220192"
Error -2147220192 indicates the owner of the queue does not have sufficient privileges to work with the queue. The user is likely missing suffcient Read access to the Queue entity.
Verify the user's Dynamics 365 security role has Read access to the Queue entity. Within a Dynamics 365 security role, privileges for the Queue entity are located on the Core Records tab.
NOTE: If you verify the owner of the mailbox record has Read access to the Queue entity, check if there are other Dynamics 365 users or queues that received the same email. You may need to verify privileges for those users as well.
