People/Contact is where your personal contacts are stored and where you can view any address books that have been set up for your organization.
Note: All the instructions below assume you are within the "People" application.
You can hover over or select any name in the Sender, To, or Cc fields of a message to see a brief summary of their contact information. This same information appears in the reading pane at the top of every entry in People.
It includes their IM status (if available), name, job title, and icons that you can select to send them a message, start an IM session with them, or create a meeting invitation addressed to them.
To create a contact, select the folder under My Contacts that you want to create the contact in, then select New.
This will open a blank contact form. Fill in any details that you want.
Click the + sign located next to each attribute to open more options. For example, if the person you're adding to your contacts has multiple phone numbers, select the + sign next to Phone to add additional phone numbers.
When you're done, click Save button to save your changes or click Discard to cancel creation of the contact.
You can add any contact that you see in a message. To add a contact from a message:
Find and select the contact that you want to edit. You can only edit contacts in the folders under My Contacts. When you select a contact, you'll see their details in the reading pane. To edit their information, select Edit. Make any changes that you want, and then click Save to save your changes or Discard to cancel.
Outlook on the Web detects contacts that have the same or very similar display names and will link them into a single view. To see which contacts have been linked, choose a contact card, and then if that contact has links, Links will show up on the action tool bar. (Not all contacts will have links.)
You can unlink a specific contact by clicking on the X.
