We have a hosted exchange application and the client is running outlook 2007. The client is getting "out of space" messages - Send folder is too large, mail is going into outbox is one message. There was a pop up box that the size was larger than allowed - with choices to delete various items - deleted mail, for example.
No other client has this issue. The size of the exchange box is set to 3GB, the client's mail is 1.7GB. The clients mailbox on another computer does not have this issue. The client is getting frustrated - she cannot send or receive mail when this happens.
