Explanation

This Warning event indicates that there are too many RPC mail submission threads on this Microsoft Exchange server. This warning may indicate that you should modify settings on the server. The maximum number of threads that the Microsoft Exchange Exchange Transport Service can use for submissions is defined by the MaxConcurrentMailboxSubmissions attribute. The default value is 20 multiplied by the number of processors that are on the server.

User Action

To resolve this error, make sure that the server is not overloaded. If the server is overloaded, use one or more of the following methods:

• Change the mail submissions thread value MaxConcurrentMailboxSubmissions by using the Set-TransportServer cmdlet.

• Consider making other changes in the Exchange environment that could decrease the load on the servers.

• For more information about message throttling options in Exchange, see Understanding Message Throttling.
