There is no feature in Entourage comparable to "fast switching" for OS users
in OS X 10.3 and higher. One way to speed it up is to use the keyboard: press
Option-Command (Apple)-Q to switch identities, press Enter if necessary to
confirm the command, use the arrow keys to select the identity you want to
open, and then press Enter.
You can also use a script if you wish. This will immediately open the
identity you want without showing the dialog box.
On your computer, go to /Applications/AppleScript/, and open Script Editor.
Paste the following in:
tell application "Microsoft Entourage"
set current identity to identity "Main Identity"
end tell
Replace "Main Identity" with the name of the identity you want to open. Then,
go File > Save As. Call the script "Open <whichever identity>", and save the
script to ~/Documents/Microsoft User Data/Entourage Script Menu Items/. You
can easily set a keyboard shortcut to the script by adding a code to the end
of the filename at this step. Read here for more on that:

Then, in Entourage, to switch identities, simply select the script from the
script menu (to the right of the "Help" menu), or press the keyboard shortcut.
You can create multiple scripts to open different identities.
(Note: "~" stands for your home folder, usually located in /Users/<Your
User>/.)
