I got an error when I try to move default offline address book generation server to other server. The original OAB generation server cannot be found. It was a testing server that was accidently deleted after migration process. To solve this problem, I need to delete the old default OAB, create new default OAB, specify the new default OAB as the OAB for all mailbox database.

This article explain about how to solve a problem of a disconnected mailbox that cannot be removed because the MaiboxGuid exist twice. The MailboxGuid of the disconnected mailbox is the same as the MailboxGuid of other active mailbox in different database.

Sometimes, we need to delete/remove a mailbox from one user account and reconnect it to other user account. When we delete/remove mailbox from Exchange 2007, we can’t see it immediately in the Disconnected Mailbox list under Recipient Configuration. In Exchange 2007, there is no GUI facility like “Run Clean Up Agent” in Exchange 2003.
To update the Disconnected Mailbox list, we need to use cmdlet in the Exchange Management Shell. Use the Clean-MailboxDatabase cmdlet against the mailbox database it was in.
Here is how to do it:
1. First, let’s list the Mailbox Databases that we have using the Get-MailboxDatabase cmdlet.
[PS] C:\> Get-MailboxDatabase
Name Server StorageGroup Recovery
---- ------ ------------ --------
Mailbox Database Server1 First Storage Group False
Executive Database Server1 Second Storage Group False
Mailbox Database Server2 First Storage Group False
Partner Database Server2 Second Storage Group False
2. Clean up the database. To clean up specific database on specific server, use these cmdlet:
[PS] C:\> Clean-MailboxDatabase "Server1\Mailbox Database"
[PS] C:\> Clean-MailboxDatabase "Server2\Partner Database"
After running the cmdlet you will see the disconnected mailbox in the Disconnected Mailbox list.
When configuring the receive connector in Exchange 2007, I find out that users using SMTP email client like Outlook Express and Thunderbird can receive email but cannot sent email through Exchange as the SMTP server. They get the following error:
“Protocol: SMTP, Server Response: ‘550 5.7.1 Client does not have permissions to send as this sender’, Port: 25, Secure(SSL): No, Server Error: 550, Error Number: 0x800CCC78”
