The below steps apply to Internet Explorer and Edge web browsers. If using Safari or Firefox, complete steps 1 and 2 and then skip to additional steps at the end of this article.

Step-by-step:

  1. Choose New mail above the folder list. A new message form opens in the reading pane.

  2. At the top of the message, choose the ellipsis (…) and select Show From. This option shows you that the people who receive the email message will see it comes from the shared mailbox and not from your own email account.

  3. The first time you use the shared mailbox, you need to add the address to the options available in the From drop-down list:

    1. Right-click the From address and choose Remove.

    2. Type the shared address. The next time you reply from the shared mailbox, its address will appear as an option in the From drop-down list.

  4. 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 on the web searches for that person’s address. In the future, the name is cached so it resolves quickly.

  5. Type a subject, add the message you want to send, and click Send when ready to send the message.

 

The sent message is stored in your own mailbox instead of the shared account’s sent items folder. To move the sent item to the correct folder:

If using Safari or Firefox, please complete steps 1 and 2 above, then proceed with the following steps.

After completing steps 1 and 2 above:

  1. Click on the From label/text itself to display a drop-down box that will display your email address and Other email address…

  2. Click Other email address… and type the email address for the shared mailbox in the From field.

  3. Once added, the next time you reply from the shared mailbox, its address will appear as an option in the From drop-down list.

  4. 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 on the web searches for that person’s address. In the future, the name is cached so it resolves quickly.

  5. Type a subject, add the message you want to send, and click Send when ready to send the message.

You will receive a “You don’t have permission to send messages from this mailbox” error message if attempting to send an email message from a mailbox you do not have permissions for.
