The problem that I am about to describe happens in any version of Outlook (XP, 2000, 98). I am trying to set the Out of Office Assistant, and whenever I do so, I am receiving the following error messages: When I first open the Out of Office Assistant, I receive the message "The AutoReply could not be displayed. The client operation failed." I then click Ok and I get into the Out of Office Assistant and set the away message. When I click Ok, I get the error "changes to the rules could not be saved. There is not enough memory or the rules are too complex. Try deleting some rules". There are no other rules installed, I have tried this from a different machine in the same mailbox and I receive the same error. I don't think the problem is on the Exchange server side, because others are able to set the assistant ok. Any ideas??
