| Description | An interoperability error occurred. A reliable transport service element (RTSE) error occurred. The checkpoint was received but not negotiated. Control block index <index name>. [<value> <value> <value> <value>] (14) |
| Event Information | According To Microsoft: The diagnostics logging levels of the message transfer agent (MTA) interface and interoperability categories should be increased to create interoperability logs. These logs are text logs that consist of the binary contents of communication among MTAs in different sites, and between MTA and client applications within a site. They are stored in the \Exchsrvr\Mtadata directory. The current log is always named Bf0.log. Prior logs are named Bfx.log, where x increases as the age of the log increases. To help Microsoft Product Support Services determine the problem, create log files. To create Ap*.log files, on the Diagnostics Logging tab of the Server Properties dialog box, select MSExchangeMTA, and then set the logging level of the Interoperability and Interface categories to Maximum. To create Bf*.log files, set the logging level of the Application Protocol Data Unit (APDU) and X.400 service categories to Maximum. Save all MTA log files (mtadata\*.log), Event Viewer output, and database files. |
