One of our exch servers failed thismorning whenthe number of transaction logsbeing producedaccelerated to approximately 100 per minute and filled the space on the drive. I've been asked to explainwhy this happened. On opening the log the same two users e-mail addresses are repeated over and over again. I've usedthe message tracking agent to examine the traffic to these mailboxes but can't find anything suspicious. Where do i go from here?
