One of the servers has managed to reach 129GB exchange store size, the limit set is 75GB. all had been working fine untill 11.51pm last night an event was recorded with ID 1159 'Database Error 0xfffffd9a occured in function JTAB_BASE::EcSetColumn while accessing the database'. From that point onward the event log records lots of MAPI session errors.
For some reason the exchange store has increased in size by nearly 100GB overnight, its not something I have seen before. I am opening a call with Microsoft regarding this but in the meantime, does anyone know about this issue or experienced it before?
