I have found a workaround to the vexing question of how to transfer group mailing lists from Entourage to Mac Mail.

This is really much less difficult than a 12-step process might seem, and most Mac veterans will pick it up quickly, but I wrote it here in great detail for the benefit of and newbies. As the Mac veteran knows the Mac is intuitive and as usual much more difficult to explain in words than to actually do in practice, and it works!

Step 1: Create or open a previously sent email in Entourage from Sent Items. (I usually send to group mailings with the addresses in the bcc address field to protect the recipients addresses from being seen by other members of the list)

Step 2: From the toolbar of the previously sent group email select “Resend.” The message appears as it was originally sent.

Step3: In the bcc field (if you use that for your group addresses) you will see the names of your group email recipients listed across the field. With a little head and shoulders figure or silhouette before each name. click on the first silhouette.

Step 4: The address fields will drop down showing “To:” “Cc:” and “Bcc:” Names and email addresses will appear in a list something like this:
Mary Smith <mary@xxxxxxxxxx.com> and so on down the list.

Emails without names will just appear as email addresses without these things: < > (The less than/greater than keys: Shift-comma and shift-period) That’s okay.

Step: 5 Click on one of the silhouettes (not the email address) in the list selecting it. Then do a “Select all” (Command-A or edit menu&#8594; Select All) The entire list will be highlighted.

Step 6: Now, the tricky part: with the mouse, grab, drag and drop the entire list into an open blank MS Word document. It should fill the page with your names and addresses.

Step 7: Even trickier: After saving the Word document, go to the Edit menu in Word and select “Replace.” In the “Find what” field put “>” (Less than character) (without quotes). In the “replace with” field put “>, ” (without quotes) That is, “less than-comma-space.” (This will be easier—especially to see the space if you turn on “show nonprinting characters” in the view section of Word Preferences. This should also be accessible in the Word Toolbar, designated by a button with the paragraph mark icon.)

Step 8: click on “Replace all” Then all email addresses will be followed by >, (less than-comma-space instead of butting up immediately against the next name or address. It will go from looking like: Mary Smith <mary@xxxxxxxxxx.com>Joe Barf <joe@xxxxx.com> to looking like this: Mary Smith <mary@xxxxxxxxxx.com>, Joe Barf joe@xxxxx.com And so on.

Step 9: Save word document. Then open Mac Mail and click on New Message and place the cursor in the Bcc address field.

Step 10: in your newly saved Word document containing your group list do “select all” as described above. Then manually click once and hold the mouse button and drag the entire highlighted text (all of it) to the Bcc field in the new email form in Mac Mail and release the mouse button. Your entire group list will appear in the Bcc field. The names will appear for those addresses with names, for those without names the email address will simply appear. Then Click on “Save as Draft” in Mail.

Step 11: Open your address book and click on the Plus sigh (+) at the bottom left of the “Group” section A new field will appear with “Group Name” in it. Name the group.

Step 12: Reopen the email you just created from the “Drafts” section on the left side of the main Mail window. Click in the Bcc field of that message and do a “Select All” highlighting all the addresses in the field. Again with the mouse grab and drag all those highlighted names/addresses to the new Group Name listing in the groups section of the address book Alternatively you can click on the group name opening a new name column and drag and drop the highlighted list there. It makes no difference. A drop-down alert will appear asking “Are you sure you want to import ____ [number] cards?” With a question mark button, a Review Duplicates button, a Cancel button and an Import button. Click “Import” and you will now have your group address list available in Mail as well as in Entourage!

You'd think Apple would automate this process. It is in Apple's interest to do so.
