How to fix incorrect msExchHomeServerName attribute after removing an Exchange Mailbox?
Posted in Windows Powershell | 4 Comments | 23,066 views | 27/03/2013 11:03

When you remove an Exchange Mailbox from DAG or your environment, msExchHomeServerName attribute remains same. You may get problem when you try to update user mailbox due to non exist Mailbox Server. In order to achieve this problem, you should get affected mailboxes first, then you should update them with correct mailbox server name.

First get all affected mailboxes:

$Mailboxes = Get-Mailbox -ResultSize Unlimited | where {$_.Servername -eq "Old_Mailbox_Name"}

Update them with this:

1
2
3
4
5
6
7
foreach ($Mailbox in $Mailboxes)
{
Write-Host $Mailbox.Name
$MBX = $null;
$MBX = Get-Mailbox -Identity $Mailbox
Set-Mailbox $MBX -Database $MBX.Database -Confirm:$false -Force -Verbose
}

After that process, all msExchHomeServerName will be corrected.

Why, when you run it, does it go through every address book in the organization? I have only run small one user tests but worry that running against 30,000+ accounts will take forever. If that is something that can be omitted for speed, can you let me know?
