Last Error: 432 4.3.2 STOREDRV; mailbox server is offline; STOREDRV.Deliver.Exception:ConnectionFailedTransientException.MapiExceptionNetworkError; Failed to process message due to a transient exception with message Cannot complete delivery-time processing
Good day!Could you tell me more details about your environment? Is it a DAG and what's the version of your Exchange server? Also when does this error message appear, after sending a message or other? If so, will other users got the same error?

Hi,
I noticed that you mentioned "sometimes my exchnage 2016 mailbox queues status stay retry and give error" in this post.
Do you have the exact same error message "MapiExceptionRpcServerTooBusy" in event 4009 as in the link you provided?
If not, please post a screenshot or text of the error message in event 4009 if possible.
(Note: Don't forget to hide your personal information for security)

Die folgende Mail hat mich vor ein paar Tagen erreicht und ich denke die Lsung knnte auch anderen weiterhelfen. Es handelt sich um einen einzelnen Exchange 2016 Server auf Windows Server 2012 R2. Hier einmal ein Auszug des Problems aus der Mail:
Nun bin ich aber am Ende meines Lateins und wollte mich erkundigen ob du eventuell einen solchen Fehler in deinen Exchange Installationen auch schon einmal hattest.. Mein Exchange Server stirbt fast Tglich mit folgenden Effekten:
Ich hatte bereits eine Vermutung wo das Problem liegt und daraufhin das Eventlog angefordert. Netterweise wurde mir das Eventlog zur Verfgung gestellt und auch ein Zeitpunkt genannt, wann das Problem zu Letzt aufgetreten ist.
Der Server hat also viel zu tun. Um zu vermeiden das einzelne Benutzer zu viele Systemressourcen auf dem Server verbrauchen und damit andere Benutzer und/oder das System ausbremsen, gibt es Throttling Policies. Throttling Policies begrenzen die Ressourcen die ein einzelner Benutzer in Anspruch nehmen kann.
Ich habe empfohlen eine weitere Datenbank anzulegen und 50% der Postfcher in die neue Datenbank zu verschieben. Hier sollte ein ausgewogenes Verhltnis herrschen um die Last mglichst gleichmig zu verteilen. Daher sollten nicht alle Power User in eine neuen Datenbank verschoben werden, sondern nur die Hlfte, der Rest kann dann mit weniger aktiven Postfchern aufgefllt werden. So lsst sich meist ein recht ausgeglichenes Verhltnis von Datenbankgre und Last herstellen. Ein Exchange Server 2016 Standard Edition kann maximal 5 gemountete Datenbanken pro Server verwalten (Enterprise Edition: 100 gemountete Datenbanken pro Server).
Durch die Nutzung mehrerer Datenbanken lsst sich die Last also besser verteilen. Auch im Hinblick auf Backup und Restore machen mehrere Datenbanken Sinn, beim Backup kann je Datenbank ein Stream geffnet werden (wenn entsprechende Software eingesetzt wird) und dadurch der Durchsatz des Backups erhht werden. Auch die Restore Zeiten knnen sich verbessern, anstatt im Fehlerfall eine groe Datenbank aus dem Backup wiederherzustellen, reicht es ggf. aus eine von mehreren kleineren Datenbanken wiederherzustellen.
In der Standardeinstellung gibt es fr alle Exchange 2016 Server eine globale Throttling Policy. In dieser Policy wird unter anderem die Anzahl gleichzeitiger Verbindungen je Benutzer/Client/Protokoll definiert. Fr den aktuellen Fall ist besonders ein Wert wichtig: RCAMaxConcurreny
The RcaMaxConcurrency parameter specifies how many concurrent connections an RPC Client Access user can have against an Exchange server at one time. A connection is held from the moment a request is received until the connection is closed or the connection is otherwise disconnected (for example, if the user goes offline). If users attempt to make more concurrent requests than their policy allows, the new connection attempt fails. However, the existing connections remain valid.
Scheinbar bezieht sich der Wert RCAMaxConcurreny der Throttling Policy allerdings auch auf die Datenbank, denn alle Verbindungen knnen aufgebaut werden, wenn 10 der Postfcher in DB1 und die weiteren 10 Postfcher in DB2 gespeichert werden. Somit wrden in Summe nur 23 Verbindungen gegen DB1 (Eigenes Postfach + 10 weitere Postfcher) und 20 Verbindungen gegen DB2 (10 weitere Postfcher) laufen.
Hi!
Danke fr die Nachricht. Gilt auch fr Exchange 2013, hier dasselbe Problem ab ca. 17 shared mailboxes.
Musste man die neue Policy nicht noch irgendwo im Exchange eintragen, oder gilt das ab der Erstellung der Policy fr die Organisation?
Lg,
Thomas
I'm trying to move journaling over to new Exchange2013 databases/journaling mailboxes running on dedicated servers. Whenever I make the journalrecipient switch messages start to backup in the delivery queues stating the thread limit has been exceeded. I've tried putting the following keys on the EdgeTransport.exe.config but no dice. I've also made sure the throttling policy applied to the EV system mailbox was set properly.
The default state for a public folder is that a single replica exists in the database where an administrator originally creates the folder unless replicas exist for the parent folder, in which case Exchange creates replicas for the new child folder in the databases where replicas exist for the parent.
By comparison to folder content, changes to the folder hierarchy are replicated as soon as they occur, so the addition or deletion of a folder should replicate throughout the organization very quickly.
You can also hide a public folder from Exchange address lists by selecting it in the Public Folder management console, view its properties, navigate to the Exchange General property page, and select the checkbox to hide the folder. Hiding mail-enabled public folders only conceals them from users. Even if you hide a mail-enabled public folder from the Exchange address lists, administrators will continue to see these objects listed in the picker dialogs used to select recipients for various tasks such as adding recipients to distribution groups.
Behind the scenes, when you mail-enable a public folder, Exchange creates a new object for the folder in the Microsoft Exchange System Objects OU. Figure 4 shows the attributes of a mail-enabled public folder as viewed through the ADSIEdit utility. The new object is used to hold properties of the public folder such as the proxy email addresses, mail tips, and so on. The properties of the new object can then be viewed with the Get-MailPublicFolder cmdlet and manipulated with the Set-MailPublicFolder cmdlet.
No system folder needs to be mail-enabled. However, you may see errors flagged when you apply an email policy to these objects. The likely cause is that these folders were enabled for email in a previous version of Exchange and their names or aliases include spaces or special characters that cannot be used in SMTP addresses, and so are found to be invalid when Exchange attempts to use them to create email addresses according to the email policy. If you see an error like this, you can disable email for the folders and remove their email addresses with this code:
The Remove-PublicFolder cmdlet deletes a public folder from the public folder hierarchy and removes all content and replicas that exist in public folder databases in the organization. The simplest deletion is to remove just one folder. For example:
When a mailbox database is created, Exchange checks the available public folder databases to decide which to associate with the new mailbox database. If a public folder database is available on the same server, it is selected. If not, the first public folder (listed alphabetically) in the organization is used. Over time, this leads to a certain imbalance in the workload going to the first public folder database. To check the current allocation of mailbox databases to the available public folder databases:
The default mechanism used to determine the best referral is based on Active Directory site link costs. First, Exchange looks for servers in the local site to see if there are public folder databases available that contain the required folder. If no local servers are available, Exchange builds a list of available servers that host public folder databases in other sites and orders them by cost. Exchange then attempts to contact each server to see whether they have an available replica and will connect to the first replica folder that it finds.
