CAUSE

This issue occurs because the attributes list of a send connector for synchronization does not include the SmtpMaxMessagesPerConnection property.

When the attributes list does not include the SmtpMaxMessagesPerConnection property, the Microsoft Exchange EdgeSync service does not replicate the property from Active Directory Domain Services (AD DS) to Active Directory Lightweight Directory Services (AD LDS).

Note The Exchange EdgeSync service is running on the on the Hub Transport server.
