需要更改两个值，分别是tombstoneLifetime和msDS-DeletedObjectLifetime

Set-ADObject -Identity “CN=Directory Service,CN=Windows NT,CN=Services,CN=Configuration,DC=contoso,DC=com” –Partition “CN=Configuration,DC=contoso,DC=com” –Replace:@{“tombstoneLifetime” = 365}

Set-ADObject -Identity “CN=Directory Service,CN=Windows NT,CN=Services,CN=Configuration,DC=contoso,DC=com” –Partition “CN=Configuration,DC=contoso,DC=com” –Replace:@{“msDS-DeletedObjectLifetime” = 365}

可以通过adsiedit.msc查看
