我被卡住了，我試圖在一個人的郵箱中找到最舊的“EMAIL”，但我不知道還能嘗試什么。我想我需要在某處添加 ContainerClass -eq "IPF.Note"，但我不確定在哪里。
以下腳本有效，但它會找到最舊的 ITEM，在我的情況下它是contact。我想分別查看每個容器（電子郵件、聊天、日歷、聯系人），但對于這個腳本，我只想知道最舊的電子郵件。
謝謝
Get-MailboxFolderStatistics -IncludeOldestAndNewestItems -Identity USERID |
Where OldestItemReceivedDate -ne $null |
Sort OldestItemReceivedDate |
Select -First 1 OldestItemReceivedDate

假設這是出于合規性原因在 Exchange 服務器上搜索郵箱中的專案，您應該使用Search-Mailbox cmdlet - https://docs.microsoft.com/en-us/powershell/module/exchange/search-mailbox?視圖=交換-ps
要讓 Exchange Online 在郵箱中搜索專案，您應該使用New-ComplianceSearch cmdlet https://docs.microsoft.com/en-us/powershell/module/exchange/new-compliancesearch?view=exchange-ps
此網頁顯示如何按日期搜索 - New-ComplianceSearch：如何使用較新版本的 Search-Mailbox https://www.codetwo.com/admins-blog/new-compliancesearch-new-version-of-search-郵箱/
這個網頁有一個腳本來搜索郵箱，包括日期PowerShell – New-ComplianceSearch 腳本來遍歷所有郵箱，找到目標郵件，并將其洗掉- https://365basics.com/powershell-new-compliancesearch-script-to -go-through-all-mailboxes-find-a-target-message-and-remove-it/
使用您原來的方法，應該這樣做。假設您有適當的權限。
Get-MailboxFolderStatistics -ID <mailboxemailaddress> -IncludeOldestAndNewestItems | select Identity, Name, FolderPath, ItemsInFolder, FolderSize, OldestItemReceivedDate | Export-Csv C:\temp\Mailbox.csv -NoTypeInformation

您可以按專案型別過濾您擁有的內容，但我會在獲取統計資訊后執行此操作，因此您只需查詢交換一次：
# Get the folder statistics for all folders
$stats = Get-MailboxFolderStatistics -IncludeOldestAndNewestItems -Identity $USERID
# Get the oldest email. Can re-use $stats for the other item types
$OldestEmail = $stats |
Where-Object {$_.OldestItemReceivedDate -and $_.ContainerClass -eq 'IPF.Note'} |
Sort-Object OldestItemReceivedDate |
Select-Object ContainerClass,OldestItemReceivedDate,FolderPath -First 1
# Outputs
ContainerClass OldestItemReceivedDate FolderPath

您是正確的，郵箱檔案夾統計命令默認不搜索可恢復的專案。除非您指定，否則它也不會搜索郵箱存檔-Archive。如果您需要這些，則必須進行其他搜索：
# Get recoverable items:
Get-MailboxFolderStatistics -Identity $USERID -FolderScope 'RecoverableItems' -IncludeOldestAndNewestItems |
Where-Object OldestItemReceivedDate |
Sort-Object OldestItemReceivedDate |
Select-Object ContainerClass,OldestItemReceivedDate,FolderPath -First 1
# Note that deleted item containers do not have an item type!
ContainerClass OldestItemReceivedDate FolderPath
