Numerous times per day, I am asked for the password for each of the 2 e-mail accounts we have in Outlook for Mac 2011. Is this normal? If we don't use the computer for a few hours, we probably have to sign in to Outlook again. Is this to be expected or might it be a ISP server or set up issue? I thought that once you sign in that's it, until you sign or log out again! I called the help desk, but they were of no help. Has anybody else experienced the same with an iMac? I am talking a few times per day.
