Viewing Advanced Tabs as was kindly suggested does not cause Exchange related tabs to appear either. I did just discover that if I create a new user the "Create an Exchange Mailbox" option does appear and if selected the Exchange tabs do display for the user. I have also found that by right-clicking on an existing user "Exchange Tasks" is an option on the pop-up menu. Apparently I was I wrong to expect that Exchange related tabs would magically appear for all our AD Users once we had installed our first Exchange server??? Would the appearance of the Exchange tabs imply that they were mailbox-enabled? Sorry for the newbie questions! Denise Grau
