Here are a few PDF documents covering simple tasks I created for our Mac users.  They cover:-

• Changing your password
• Configuring Exchange in Entourage
  
• Importing Email

They are a little rough and ready, but available for anyone to use freely. 

Setting up your gmail account in Entourage is a two stage process.

1. Enable POP on your Gmail account
2. Set up the account in Entourage

How do I enable POP?

You can retrieve your Gmail messages with a client or device that supports POP, like Microsoft Outlook or Netscape Mail.

To enable POP in your Gmail account:

1. Log in to your Gmail account.
2. Click Settings at the top of any Gmail page.
3. Click Forwarding and POP in the orange Mail Settings box.
4. Select Enable POP for all mail or Enable POP for mail that arrives from now on.
5. Choose the action you'd like your Gmail messages to take after they are accessed with POP.
6. Configure your POP client* and click Save Changes.
