A lot of lawyers tend to have all of the information they would normally have on a business card pasted to the bottom of their email in a signature block. Outlook makes it very easy to add this information to your contacts list.
Simply drag the email from your inbox to the Contacts tab in Outlook 2010.
This will bring up a new contact card and already have some of the contact information filled in. Additionally, in the notes section of the card will be the email. You can highlight and drag the relevant portions of the contact information to the respective fields on the contact card. This way you don't have to worry about mistyping any of the information.
Once you have all of the information plugged in, you can simply delete the email from the notes section of the card and hit save.
Now, you've quickly added all of the sender's information to your contacts list. And it was much simpler than retyping it all.
