When typing a recipient's name in the "To:" field, Mail.app will bring up an autocomplete menu showing all email addresses for that recipient (e.g., Home and Work). If I don't pay attention and just hit Enter or Tab to autocomplete the recipients name, Mail.app picks the first address.
Is there a way to choose the default email address that Mail.app selects for the autocomplete of a recipient? I'm not sure if this settings resides in Mail.app or the Address Book.
Example
In the example below, there are two email addresses for the recipient. Mail.app defaults to the Home email, whereas I'd prefer it to default to the Work email for this contact.
Best Answer
You can if you have the contact in a group in Address Book. Select the group, then go to Edit > Edit Distribution List... You can select the contact's default email address (the default one is marked in bold). As far as I know, this only sets the default address when emailing that group, though. I don't know of a way to set a default address for a "normal" contact. (After trying to figure out a way off and on for several years, I'm inclined to say it isn't possible, but hopefully someone will prove me wrong.)
