If a Microsoft Exchange Server 5.5 recipient object contains a comma (,), equal sign (=), or plus (+) in the directory name, the Active Directory Connector (ADC) may disable the mail object in Active Directory.


This problem can occur if the Exchange 2000 ADC Local.map file has been updated to include one or both of the following mappings: "Mailbox to user" or "Custom Recipient to Contact":
In addition, the Exchange Server 5.5 recipient object has a comma (,), equal sign (=), or plus (+) in the directory name (on the Advanced tab in the Exchange Server 5.5 mailbox).

Those objects that have a comma (,), equal sign (=), or plus (+) in the directory name (LastName, FirstName) in Exchange Server 5.5 are replicated to the ADC as mail-disabled in the Active Directory. The legacyExchangeDN attribute on the Active Directory object reads ADCMailDisabledbyADC. The same problem applies to "Custom Recipient to contact" mappings in the Local.map file.
