Add the sender of a message to your Outlook contacts
You can automatically create an Outlook contact for anyone who sends you a message. After you add a sender to your Outlook contacts, Outlook does not classify future messages from that sender as junk mail.
In the message list, click the message.
Tip If the message is part of a conversation, expand the conversation, and then select the message that you want.
On the Message menu, point to Sender, and then click Add to Contacts.
