Powershell Foreach循环邮箱

Question

我正在尝试记录来自邮箱的统计信息，并且一直在使用以下功能，在这种情况下是共享邮箱

Function Shared 
{
$strUserDetails=@()
$Filename = $Save_Path + $SFilename
$Shared_MBX = (Get-Mailbox -recipienttype sharedmailbox -ResultSize Unlimited -SortBy Name)
foreach ($mbx in $Shared_MBX)
{
$upn = Get-Mailbox $mbx.DisplayName | Select UserPrincipalName
$UserMailbox = get-mailboxstatistics -Identity $($mbx.DisplayName) | Select DisplayName, ItemCount,TotalItemSize 
$ItemSizeString = $UserMailbox.TotalItemSize.ToString()  
$strUserDetails = @(
$UserName = $upn
$ItemCount = $UserMailbox.ItemCount
$strMailboxSize = "{0:N2}" -f ($ItemSizeString.SubStrin(($ItemSizeString.IndexOf("(") + 1),($itemSizeString.IndexOf(" bytes") -  ($ItemSizeString.IndexOf("(") + 1))).Replace(",","")) 
)
  $strUserDetails += New-Object psobject -Property @{Items=$ItemCount;Size=$strMailboxSize;Name=$UserName}
} 
$strUserDetails | Export-Csv -NoTypeInformation -Append -Path $Filename
}

当我在完成后检查csv时，我会期望所有共享邮箱的UPN，Itemcount，大小，但我只能获得一个

请告诉我哪里出错了

Answer 1

$strUserDetails += New-Object psobject -Property @{Items=$ItemCount;Size=$strMailboxSize;Name=$UserName}

这是你的问题，+ =这里什么都不做，并且充当=。您正在为每个邮箱创建一个新对象，并覆盖。结果只会获得最后一个邮箱。

  

方法调用失败，因为[System.Management.Automation.PSObject]不包含名为＆＃39; op_Addition＆＃39;的方法。

在foreach循环之前创建一个数组。然后，为每个循环添加一个PSCustomObject。例如：

$strUserDetails = @()
foreach ($mbx in $Shared_MBX)
{
    $strUserDetails += [PSCustomObject]@{
        Items=$ItemCount
        Size=$strMailboxSize
        Name=$UserName
    }
}

$strUserDetails

这是用MCVE解决问题的一个例子。

使用您提供的帮助

Function Shared 
{
write-host "Running Shared Mailbox extract." -ForegroundColor Cyan
$Mailboxes = (Get-Mailbox -recipienttype sharedmailbox -ResultSize Unlimited)   
$Filename = $Save_Path + $SFilename
Write-Host "This will save the extract file to " $Filename
foreach ($mbx in $Mailboxes)
{
    $strUserDetails = @()
    $upn = Get-Mailbox $mbx.DisplayName | Select UserPrincipalName
    $UserMailbox = get-mailboxstatistics -Identity $($mbx.DisplayName) | Select DisplayName, ItemCount,TotalItemSize 
    $ItemSizeString = $UserMailbox.TotalItemSize.ToString()  
    $UserName = $upn.UserPrincipalName
    $ItemCount = $UserMailbox.ItemCount
    $strMailboxSize = "{0:N2}" -f ($ItemSizeString.SubString(($ItemSizeString.IndexOf("(") + 1),($itemSizeString.IndexOf(" bytes") - ($ItemSizeString.IndexOf("(") + 1))).Replace(",","")) 
    #Write-Host  "Accessing stats for mailbox:" $username
    $strUserDetails = [PSCustomObject]@{
        Name=$UserName
        Items=$ItemCount
        Size=$strMailboxSize
        }
    $strUserDetails | Export-Csv -NoTypeInformation -Append -Path $Filename
}
Write-host "Completed Shared Extract" -ForegroundColor Cyan
}
