Dear All I am using Windows 2008 AD and Exchange 2010 for email server. I would like to know if I delete user account at AD how would Exchange server will handle with the related mailbox? As far as I know, If I delete exchange mailbox , the regarding domain user object will also be deleted. It will show the mailbox disconnected at Exchange EMC.

Hello, for Exchange please ask in http://social.technet.microsoft.com/Forums/en/category/exchangeserver/Best regards Meinolf Weber MVP, MCP, MCTS Microsoft MVP - Directory Services My Blog: http://msmvps.com/blogs/mweber/ Disclaimer: This posting is provided AS IS with no warranties or guarantees and confers no rights.

Hi, Towards the Exchange server 2010, there are two options to deal with the mailbox. 1. Disable-Mailbox Use the Disable-Mailbox cmdlet to disable the mailbox of an existing user or InetOrgPerson object and remove that object's Exchange attributes from Active Directory. The user account associated with the mailbox remains in Active Directory, but its no longer associated with a mailbox. 2. Remove-Mailbox Use the Remove-Mailbox cmdlet to delete the user account associated with a particular mailbox from Active Directory and to process the associated, disconnected mailbox as directed by the specified parameters. I hope the description above is helpful to you to have a better understanding between AD and mailbox. Regards, JamesJames Xiong TechNet Community Support
