You can change mail preferences to personalize your mail
experience.
How do I add my signature to emails?
You can add your signature to email messages. Signatures
can include your name, title, graphics, vCard, and other information.
How do I view emails as conversations?
You can view a message grouped with all of its replies
so that you can read the message and replies all at one time. A message
grouped with all of its replies is called a conversation and conversations
save you the trouble of looking through your Inbox to find individual
replies.
How do I change who is added to the type-ahead list?
The addresses that appear in the type-ahead list are chosen
automatically, based on the people with whom you recently emailed,
chatted, and had meetings. You can change whether or not CC and BCC
recipients are added to the type-head list, or whether to add names
from all emails or just from emails you send. You can also choose
to stop adding any names to the type-ahead list.
