Please Help me out with a Lotus Notes 5 question, I'm desperate here!!!

[net1994]

Hi, I just joined a company and my boss has placed me in charge of managing our Lotus Notes 5 system. While I have a good understanding of how to do a good deal of things in Notes, I?m not yet a Master of it. My boss just asked me to do two things in Notes that I have no idea of how to do or where to even start, so I really need some help. An employee at our company has just left and my boss wants me to disable the Notes account of this person. He also want me to have a ?pop-up? notice saying that ?This employee no longer works at the company,? whenever someone sends, or tries to check the e-mail to this newly disabled account. Can someone please help me out with these two questions I have, so I can then do it on my own. Thanks a lot and who ever helps me out, is a lifesaver.
