A Windows XP system which I had installed Outlook 97 several months ago has suddenly started having a problem with the MAPISP32.EXE process. When Outlook 97 is invoked, this process takes over the system using 98-99% of the CPU. It continues to run enven after Outlook 97 is terminated. Could this situation be caused by a resent update to windows xp? I have not been able to located any information on this - any ideas?
