Powershell獲取Exchange 郵箱用戶配額

    客戶場景：為很多用戶單獨配置過郵箱配額，想重新規劃，現需要導致所有用戶實際容量清單
    實現方式：直接上代碼

#加載Exchange命令
Add-PSSnapin Microsoft.ex*
#主命令
[array]$output = "" | Select Name,ProhibitSendQuota,DBName
$DBs = Get-MailboxDatabase | Select Name,ProhibitSendQuota
foreach ($DB in $DBs) {
[string]$DBQuota = $DB.ProhibitSendQuota
[string]$DBName = $DB.Name
Write-Host "Database $DBName's quota is $DBQuota"
$Mails = Get-Mailbox -Database $DBName | Select Name,ProhibitSendQuota
foreach ($Mail in $Mails) {
if ($Mail.ProhibitSendQuota -eq "Unlimited") {
[string]$MailQuota = $DBQuota
}
else {
[string]$MailQuota = $Mail.ProhibitSendQuota
}

$Temp = "" | Select Name,ProhibitSendQuota,DBName
$Temp.Name = $Mail.Name
$Temp.ProhibitSendQuota = $MailQuota
$Temp.DBName = $DBName
#$Temp

$output += $Temp

}
}
$output | Export-Csv MailQuota.csv -NoTypeInformation -Encoding UTF8
輸出結果：

與預期對比：

結論：如果為用戶配置了不限制容量，則不能正常獲?。蛻魧嶋H環境中僅為董事長有配置無限制，手動修正，符合客戶需求），歡迎幫解決此bug

    Update:
    客戶提出了幾點疑問：
    1. 這個結果我無法看出哪些用戶是有手動配置過的
    2. 我不知道用戶使用了多少，用了多少空間
    3. 需要最后登錄時間
    4. 我有很多Mail Server，如果我只想獲取一臺怎么辦？
    5. 我在C盤打開的這個腳本，但這個腳本實際位置在D盤，這個輸出文件輸出到了C盤怎么辦？需要輸出到腳本所在的目錄

針對以上，優化了腳本：

1. 先直接上腳本
   param($Server)
   $outfile = $(Split-Path -Parent $MyInvocation.MyCommand.Definition) + "\" + (Get-Date -UFormat "%Y-%m-%d_%H-%M-%S") + ".csv"
   Write-Host $outfile
   [array]$output = "" | Select Name,DBName,UserQuota,DBQuota,ProhibitSendQuota,TotalItemSize,Use,LastLogonTime
   #Select Name,DBName,UserQuota,DBQuota,ProhibitSendQuota,TotalItemSize,Use
   Add-PSSnapin Microsoft.ex
   if($Server){
   $DBs = Get-MailboxDatabase -Server $Server| Select Name,ProhibitSendQuota
   } else {
   $DBs = Get-MailboxDatabase | Select Name,ProhibitSendQuota
   }
   foreach ($DB in $DBs) {
   [string]$DBQuota = $DB.ProhibitSendQuota
   [string]$DBName = $DB.Name
   Write-Host "Database $DBName's quota is $DBQuota"
   $Mails = Get-Mailbox -Database $DBName -ResultSize unlimited | Select SamaccountName,ProhibitSendQuota
   foreach ($Mail in $Mails) {
   if ($Mail.ProhibitSendQuota -eq "Unlimited") {
   [string]$MailQuota = $DBQuota
   }
   else {
   [string]$MailQuota = $Mail.ProhibitSendQuota
   }
   $TotalItemSize = Get-MailboxStatistics -Identity $Mail.SamaccountName | select TotalItemSize,LastLogonTime
   $TempA = $Mail.ProhibitSendQuota
   $Temp = "" | Select Name,DBName,UserQuota,DBQuota,ProhibitSendQuota,TotalItemSize,Use,LastLogonTime
   $Temp.Name = $Mail.SamaccountName
   $Temp.DBName = $DBName
   if ($TempA -eq "Unlimited") {
   $Temp.UserQuota = $TempA
   } else {
   #$Temp.UserQuota = $TempA.replace(" ","").split("(")[0]
   $Temp.UserQuota = $($TempA -replace " ").Split("(")[0]
   }
   $Temp.DBquota = $($DBQuota -replace " ").Split("(")[0]
   $Temp.ProhibitSendQuota = $($MailQuota -replace " ").Split("(")[0]
   $Temp.TotalItemSize = $($TotalItemSize.TotalItemSize -replace " ").Split("(")[0]
   $Temp.Use = ('{0:n2}' -f $($Temp.TotalItemSize / $Temp.ProhibitSendQuota 100)) +'%'
   $Temp.LastLogonTime = $TotalItemSize.LastLogonTime
   #$Temp

$output += $Temp

}
}
#$output[1..$output.count]
$output[1..$output.count] | Export-Csv $outfile -NoTypeInformation -Encoding UTF8 -Force

2. 輸出結果
   
3. 腳本執掃方式
   a. 直接執行則獲取所有用戶
   b. .\xxx.ps1 -Server XX則獲取指定Server上的DB

歡迎補充
