前段时间迁移公司邮箱，涉及到新老邮箱账户信息对比。要把SamAccountName和Alias不相同的邮箱用户整理出来，做单独的对比。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 ActivedirectoryAdd-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
