Manche Systemmeldung eines Exchange Servers enthalten nur die GUID msExchMailboxGUID des reklamierten Postfachs. Anhand dieser GUID kann das Postfach identifiziert werden. Umgekehrt kann man die GUID eines Postfachs mit dem Get-Mailbox Kommando herausfinden (Zeile 7):
[PS] C:\Windows\system32>get-mailbox dude | fl Name, *Guid*Name : dude
ExchangeGuid : ec85efae-1d78-4288-9b5e-717163a58da4
MailboxContainerGuid :
AggregatedMailboxGuids : {}
ArchiveGuid : 00000000-0000-0000-0000-000000000000

Guid : e0258f7c-8f1b-4b17-bd34-85318d74afc7
Hat man die GUID gibt das Get-MailboxStatistic Kommando uA die Informationen zum Postfach aus dem Active Directory zurück, die Ihnen bei der Identifizierung weiterhelfen:
