I can´t create mailboxes after a big crash RRS feed

  • Question

  • My Exchange Server died.... RIP... I formatted the server, installed Windows Server 2008 Standard and Exchange Server 2010... there is nothing else in the server.... Believe or not, the previous server lasted only 3 days and I didn´t have the chance to make backups... Now when I try to add mailboxes there are no users available..... 

    If I try to create new mailboxes it creates new users...... how do I create mailboxes to current members of the domain? Helpppppppppp

  • Users are in Active Directory, and losing an Exchange server won't cause users to disappear.  Their mailboxes will disappear, but the user objects will still exist and they'll still think their home is on the old Exchange server.

  • Exactly!  Deleting the server doesn't delete their mailboxes in AD, their user accounts still have all the Exchange properties.  Is the server named differently?

    If you just installed a new Exchange server and didn't remove the old one, then what I recommend you do is uninstall all Exchange roles from the new server.  Then rebuild the server with the same name as the old one, and configure all the disk drive letters the same as the old one.  Then run Exchange setup with the /Mode:RecoverServer switch and it'll build everything just like the old one,  mount all the databases if they aren't already mounted, and when users connect, they'll all have new mailboxes without you having to do anything.

    When you installed the new Exchange server did you name it the same as
    the one that died? Probably not. If that's the case then the AD still
    has the old mailbox location as part of the AD User's properties.
     
    You could try this (it should be the same as the old
    "-configurationonly" switch):

  • Do you have a domain controller?  Are there user accounts?

  • this is the estructure of the network..... one domain server with applications working fine... last week I added a new domain server in order to install exchange, making them 2 domain servers.... Exchange was working perfectly...everything was fine, the emails were fine until the hard disk died (3 days after installation). I installed a new hard drive, new windows and exchange again from cero.... now when I try to add mailboxes and press add to current users only appears one user I added yesterday... seems like users have mailboxes somewhere else... Is the a way to revert that?

  • Hi,

    1. Crate a CSV with the following fields for all AD user objects:

    Lastname,Firstname,Name,UserPrincipalName,Password

    2. Make the script and save as ps1 :

    Import-CSV C:\users.csv | ForEach-Object -Process {New-Mailbox -Name $_.Name -FirstName $_.FirstName -LastName $_.LastName -OrganizationalUnit $_.OU -UserPrincipalName $_.UPN -Alias $_.alias -Database "Name of database" -Password $Password}

  • the AD has all users intact... the problems appears when I try to read them from the new mailbox wizard. It seems like all users have already a mailbox and are not available to selection
