Problem mit Throttling Policy?

[woiza 10]

Hallo,

 

ich habe ein Problem mit meinem Exchange Server. Ein Dienstleister ist gerade dabei mit einem Tool Inhalte von Notes auf Exchange zu verschieben.

 

Dazu meldet sich das Tool wie Outlook am Exchange 2013 an. Ein Serviceaccount für das Tool wurde erstellt und hat Vollzugriff auf die Mailboxen (receive-as). Das funktioniert soweit, nur bei einigen Usern kommt es zu folgendem Fehler:

 

11:27:25 ERROR: [4970-24-52-8004011D]Unable to open mailbox for user 'test@xxx.com'
11:27:25 OpenMsgStore:
11:27:25 MAPI error 8004011D
11:27:25 Error: Your server administrator has limited the number of items you can open simultaneously. Try closing messages you have opened or removing attachments and images from unsent messages you are composing.
11:27:25 Component: Microsoft Exchange Information Store
11:27:25 Low level error: 000004DE
11:27:25 Context: 0000054A
11:27:28 Using admin privilege to open mailbox.
 

 

Kennt jemand den Fehler? Kann das an der Throttling Policy liegen? Die wurde eigentlich bereits für die meisten Werte auf Unlimited gesetzt?

• Cause

  Cause 1:

  The Exchange account does not have permissions to the mailstore - it is likely a separate mailstore, which is why the mail is successfully migrated to the mailbox but not the server-based archive mailbox.

  Cause 2:

  In Exchange 2010 and later, there are limits regarding the numnber of MAPI sessions a single user can have open. The limit is set at 32 by default. In this case, an Event ID 9646 should be logged on the Exchange mailbox server (Exchange 2013) or CAS server (Exchange 2010) that NME is configured to connect to.

   

• Resolution

  Resolution 1:

  1. Launch an Exchange Management Shell.

  2. Type (in one continuous line where <migadmin> is your Receive As migration account):

  get-mailboxdatabase | add-adpermission -user <migadmin> -extendedrights Receive-As

  3. Then retry migration.

  Resolution 2:

  The following two Microsoft knowledge base articles describe the issue and possible solutions:

   

  Refer to Microsoft KB Article ID: 2742012 – “An event ID 9646 occurs when a service account opens many MAPI sessions on an Exchange Server”

   

  Refer to Microsoft Technet Article – “Exchange Store Limits”

Wenn du in die Throttling Sachen läufst, gibt es beim Exchange Server Einträge in der Ereignisanzeige.
