Exchange - 查找SamAccountName和Alias不相同的邮箱用户

前段时间迁移公司邮箱，涉及到新老邮箱帐户信息对比。要把SamAccountName和Alias不相同的邮箱用户整理出来，作单独的对比。下面是命令&脚本：

• 命令：

  Get-Mailbox -ResultSize Unlimited | where {$_.SamAccountName -ne $_.Alias}

• 脚本

# 加载 Exchange、AD 模块
Import-Module Activedirectory
Add-PSSnapin Microsoft.Exchange.Management.PowerShell.E2010 -ErrorAction SilentlyContinue

# 获取SamAccountName和Alias不相同的邮箱用户
$Mailbox = Get-Mailbox -ResultSize Unlimited | where {$_.SamAccountName -ne $_.Alias} | foreach {$_.SamAccountName}

# 准备输出集合
$GlobalExport = @()

# 循环处理邮箱用户
foreach ($user in $Mailbox) 
{
    $enableuser = Get-aduser -Identity $user | ?{$_.Enable -eq "True"}
    $Mail = Get-Mailbox -ResultSize Unlimited $enableuser.SamAccountName
    $Obj = New-Object PSObject
    $Obj | Add-Member NoteProperty -Name "SamAccountName" -Value $Mail.SamAccountName
    $Obj | Add-Member NoteProperty -Name "Alias" -Value $Mail.Alias
    $Obj | Add-Member NoteProperty -Name "PrimarySmtpAddress" -Value $Mail.PrimarySmtpAddress
    $Obj | Add-Member NoteProperty -Name "UserPrincipalName" -Value $Mail.UserPrincipalName
}
# 导出输出到CSV
$GlobalExport | Export-Csv f:\scripts\Mailbox.csv -Encoding UTF8
