- Right-click your primary mailbox in the left navigation pane, and then choose Add shared folder. (Your name is on your primary mailbox.)
- In the Add shared folder dialog box, type the name or email address of someone who has shared a mailbox with you, and then select Add.
The shared mailbox displays in your Folder list in Outlook Web. You can expand or collapse the shared folders as you can with your own folders.
SEND EMAIL FROM A SHARED MAILBOX
Select New mail above the folder list. A new message form opens in the reading pane.
Select More (•••), and then select Show From. This option shows you that the people who receive the email message will see that it comes from the shared mailbox and not from your own email account.
Note: The first time you use a shared mailbox to send an email, you won’t see the name of the shared mailbox account in the Show From drop-down. For your first-time use, delete your name, type the name of the shared mailbox in place of your name, and then send the message. In the future, the name of the shared mailbox will display in the drop-down next to Show From, and you can select it.
To add recipients, type the name of anyone who is in your contacts folder or organization’s address list, or type the email address in the To or Cc box. The first time you enter a person’s name, Outlook Web App searches for that person’s address. In the future, the name is cached so it resolves quickly.
Type a subject.
Type the message you want to send.
When your message is ready to go, select Send
