Made a small discovery the other day. Next to the visible Receive and Send Connectors, there are also Invisible Send Connectors available on the Exchange server. The one I found is called Intra-Organization Send Connector, which is used to transport messages within the organisation, between the Hub transport serves, Edge Transport Server and old Exchange servers. It is not visible in the console or when you use Get-SendConnector command.
Here’s the command to configure protocol logging for Intra-Organization Send Connector:
Set-TransportServer “TRANSPORT SERVER NAME” -IntraOrgConnectorProtocolLoggingLevel verbose
Here’s how to fix the Exchange ActiveSync error Event ID: 1053.
Exchange ActiveSync doesn’t have sufficient permissions to create the "CN=John Doe,OU=Random users,OU=Users,OU=Random OU ,OU=Random Sites,DC=random,DC=com" container under Active Directory user "Active Directory operation failed on DC.random.com. This error is not retriable. Additional information: Access is denied.
Active directory response: 00000005: SecErr: DSID-031521D0, problem 4003 (INSUFF_ACCESS_RIGHTS), data 0
Make sure that the user has inherited permission granted to domain\Exchange Servers and right to allow List, Create child, Delete child of object type "msExchActiveSyncDevices" and doesn’t have any deny permissions that block such operations.
Open the User properties in Active directory and take away the permissions for the object in question and then add it again. This should fix the problem.
