http://social.technet.microsoft.com/Forums/en/exchangesvrgeneral/thread/4306687d-4070-4975-a0b4-39caec996526 Hi, Related to this issue the where i can search the recipient in ADSIEDIT.msc meaning where to drill down.

Hi, First make sure if the Mailbox exist or not? If it Exists, confirm the Associated User Account's Location in AD (EMC -> Mailbox Properties -> Organizational Unit) Then, Adsiedit.msc -> Default Naming Context -> Domain Name -> "Organizational Unit where the User Belongs to" -> You will find the user account there. If Mailbox does not exist, Most Probably the User account would be in "Users" Organizational Unit..!! -NS

Hi Nair, The user is no more in AD. So that is the difficulty now and in the "user" and in the user container also not available. Its really strange. Dont know how to locate it. But I will get the event every 15-30 minutes (1022) Manju

Hi manjurainbow123, The Error 1144 means that when Hub server tries to deliver a mail for a user, it gets pointed to a specific mailbox server SG01\MBX01 by a DC and it turns out that mailbox is no more located there. Please run the “Clean-MailboxDatabase” cmdlet against the database “SG01\MBX01” and check this issue will occur or not.
