Someone has accidentally created a 'New Mail User' in Exchange 2007. This create an AD account however, we are unable to send email to the user. The user has been logging into the AD and using resources, and I would like to do this without losing his SID - aka i don't want to delete his account and re-create it correctly. How can I convert his 'Recipient Type Details' from a 'Mail User' to a 'User Mailbox' (Regular user) I ran the following from the Exchange shell:Set-Mailbox "UserLastName, UserFirstName" -Type Rgularand received the following output."Set-Mailbox : UserLastName, UserFirstName is not a ailbox user.In AD - it shows an SMTP address for the user, however they have no 'Mailbox Features' tab. How canconvert his 'Recipient Type Details' from a 'Mail User' to a 'User Mailbox' (Regular user)?Any help is appreciated.ZachZach Smith

Hi Zach,Did you try by enabling the mailbox with Enable-Mailbox cmdlet for the user? Specify the database to create a mailbox...Enable-Mailboxhttp://technet.microsoft.com/en-us/library/aa998251.aspxAmit Tank | MVP - Exchange | MCITP:EMA MCSA:M | http://ExchangeShare.WordPress.com

Creating mailbox for an existing user runs internally powershell Enable-Mailbox cmdlet :)Thanks for sharing your solution here...Amit Tank | MVP - Exchange | MCITP:EMA MCSA:M | http://ExchangeShare.WordPress.com

Does the solution mean that in powershell a Disable-MailUser must be run before Enable-Mailbox or else it will not be possible to conver a MailUser to UserMailbox? Thanks Anu MelkoteAnu

Tnx Brian!!! This makes it a lot easyer, since we were first trying to do this via a script (and removing certain attributes)

Hi, I am getting below error, tried the command with -DomainController also. thanks in advance for the suggestions!
