Existing users, 
Secondly, there's no indication in the list of "what's new" here that anything has been done to fix a bug in Entourage that Microsoft acknowledged MONTH and MONTHS ago, specifically, that when one receives an html email and authorizes it to download, it often becomes impossible to add email accounts or open for edit any existing ones. The only workaround is to quit the Entourage and restart it, which "fixes" the problem until the next time, which may be minutes later, as one views another HMTL email.
Thirdly, the inability to globally allow the downloading of HTML elements does not exist (as it did with the original OS X version, I might add). So one has to tediously click to authorize each time, significantly slowing workflow. Microsoft may have put this "feature" in to protect us from viruses and spyware, but - hello! MS! - that's a Windows problem, not a Mac OS X problem. I'm a Mac support pro and I haven't seen a Mac-infecting virus on a Mac in over eight (maybe even ten) years... At least give ME the option to decide if I need MS' "protection".
This is a real killer application, especially the 2004 version that allows organizing by project, but it's grossly hampered by the above flaws. And, if anyone at MS even reads these comments, it's always boggled my mind that there's no easy way (at least that I can discover) to use contextual menus or any other SIMPLE way to add someone's address to an existing email list. One should be able to click on a "from"address in an incoming message to not only created an address book listing (which is now possible), but then similarly easily to add that address to an existing email list from either the card in the address book or even directly from the incoming email itself. Such an obvious and easy to engineer capability would take an enormous amount of hassle out of address book and email list upkeep.
C'mon, MS...let's see you get these issues fixed and see some real increases in efficiency.
