Remove disconnected mailboxes in Exchange 2007

In Exchange 2007, there are two options to delete a mailbox:
1.  Remove Mailbox
2.  Disable Mailbox
If you remove a mailbox, the mailbox data that is stored in the Exchange mailbox database is marked for deletion and the associated user account is also deleted from Active Directory. If you disable a mailbox,  the user account is retain, it will only disassociate the mailbox data from the user account.

Exchange retain disconnected mailboxes in the mailbox database based on the deleted mailbox retention settings configured for that mailbox database. In Exchange 2007, the default retention period is 30 days.  During this time, the disconnected mailbox can be recovered by associating it with an existing Active Directory user account.  After the specified retention period, a disconnected mailbox is permanently deleted from the Exchange mailbox database.

How to update the Disconnected Mailbox list in Exchange 2007

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.

Facebook for Windows Mobile 6 Phone

I’ve heard about Facebook application on Blackberry.  I’ve also seen a Facebook application on my wife phone, but I don’t have Facebook application on my Windows Mobile PDA.  Usually I used the browser on my PDA to access Facebook.    That was history.  Windows just released a Facebook application for Windows Mobile 6 phone.  I just installed it.  I find something realy nice in the application.  I can have my contacts/friends list shown like my contact list in my phone.  I can easily send message to them or even call them.   It is also easy to capture and upload photos/videos directly from the application.   Actually, I rarely use Facebook.  Sometimes, almost a month I don’t even visit facebook.  Maybe this application will make me visit Facebook more. 🙂
