|Component:||Microsoft Exchange Message Transfer Agent|
|Message:||Association Recovery Failed – Original RTSE Control Block not found. Incoming RTSE CB <number>. [<value> <value> <value> <value>] (12)|
This event occurs when Exchange first encounters a problem with moving a message across a network. If the problem is not severe enough that it can not be recovered from, then this is the only information provided in the application log. If the connection cannot be recovered, then MSExchangeMTA events 9316 and 9318 may be logged, indicating that message delivery has failed.
Although this error is probably not severe, this problem is likely the cause of Network Connectivity. If these symptoms are observed, troubleshoot the network.
