| Event Information | 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. |
