My Deleted Items folders (and some others) appear to hold no more than 14 messages. After that number is reached, the older ones disappear.
Also often I can't open a message - I get the alert "The contents of this message cannot be found." when looking at it in the preview screen, and if I try to open it I get two more messages: "A problem has occurred while trying to open this message" and "A problem has occurred. Please try again."
Trying again does nothing. The messages where this happens aren't all from the same person, and it doesn't happen every time from any one person.
Live Mail was working okay for a year or so, but then started acting like this. Messages that are older (restored from my old computer) seem to be okay as far as opening them, but still disappear if I put too many of them in Deleted Items.
