Thanks David.
I have solved this. The problem was that my cumtomer had enabled too many users and changed policy that started moving a lot of data. They didn't have enough disk space for exchange log files and moving data from exchange created lots of logs...
I stopped services, cleared the queue, changed policy and then restarted services and also rescheduled the archiving tasks. This cleared everything and now everythings the way it should be.
