If I export a calendar as a .pst file on one computer then open or view it on another it looks fine.
If I then try and import that file (no duplicates) into a completly empty personal calendar many of the appointments have the word copy: inserted at the beginning of the subject line. This seems to occur on any appointment where I have invited other people.
Since there appears to be no way of doinung a find and replace (I thought MS products were meant to all have similar functionality) this is really annoying.
