SYMPTOMS
Consider the following scenario. You create an e-mail message in Microsoft Outlook. You insert a large distribution list in the To box, in the Cc box, and in the Bcc box. You then expand the distribution list in one or more of the boxes. Then, you send the e-mail message. In this scenario, it takes longer than expected for the recipients to receive the e-mail message.



CAUSE
This problem occurs when some of the users, the contacts, or the groups that are in the large distribution list have their legacyExchangeDN attribute set to the ADCDisabledMail value. If you disable the mailbox for one of the following items, the legacyExchangeDN attribute of the mailbox is set to the ADCDisabledMail value:
 * a user
 * a contact
 * a group
