為什麼交換自定義保留政策變回以前的政策

我設置了一個自定義保留策略，但是大約一個小時後，保留策略又變回了以前的策略。知道為什麼會發生這種情況嗎？我已經通過 Powershell 設置了幾次保留策略，並且它一直在恢復。

• 我應該補充一點，郵箱目前已滿，這就是為什麼我要應用新策略來騰出空間。郵箱目前無法使用。

風俗：

Name                 RetentionPolicyTagLinks
----                 -----------------------
15 Month Delete      {15 Month Delete - All, Junk Email - 7 Day, Deleted Items - 30 Day}

回歸到：

Name                 RetentionPolicyTagLinks
----                 -----------------------
Company MRM Policy   {1 Year Delete}

試圖將策略手動強製到郵箱

Powershell>Start-ManagedFolderAssistant -Identity "email@domain.com"
Powershell>
Powershell>
Powershell>
Powershell>Get-MailboxFolderStatistics "email@domain.com" -FolderScope Inbox | Format-Table Name,FolderPath,ItemsInFolder,FolderAndSubfolderSize

Name                 FolderPath            ItemsInFolder FolderAndSubfolderSize
----                 ----------            ------------- ----------------------
Inbox                /Inbox                       177017 84.44 GB (90,667,087,358 bytes)
....

還嘗試使用合規搜尋 + 操作

Powershell>New-ComplianceSearch -Name "Remove older than 15 month messages" -ExchangeLocation "email@domain.com" -ContentMatchQuery "(Received <= $((get-date).AddMonths(-15).ToString("MM/dd/yyy")))"

Powershell>New-ComplianceSearchAction -SearchName "Remove older than 15 month messages" -Purge -PurgeType SoftDelete

Confirm

您能否嘗試在 EAC 中分配保留策略並檢查此問題是否仍然存在？

在將保留策略分配給使用者後執行 Start-ManagedFolderAssistant。然後確認問題是否仍然存在。

另外，這個問題是針對所有使用者還是特定使用者？
