The first option will add the mailbox more for viewing purposes. You will be able to read email from the shared mailbox but whenever you want to send an email "from" the shared mail box, you would always have to click on "from" button and drop the box down from your personal email to the shared mailbox email. Also, your shared mailbox sent mail and deleted mail will always be in your personal sent and deleted mail folders.

The second option will add the mailbox so that you are "acting" as this particular mailbox. If you are in the shared mailbox for example, the "from" field will automatically default to the shared mailbox (no manual drop-down necessary) and the sent and deleted items will show up in the shared mailbox's sent and deleted item folders instead of your personal sent and deleted items folders.

First option to connect a shared mailbox in Outlook:

1.  Open Outlook

2.  Click on "File" tab in the top left

3.  Account Settings  > Account Settings (see image below)

4.  Double click on your email account (see image below)

5.  Click on "More Settings" (see image below)

6.  Click on "Add" additional mailboxes under the "Advanced" Tab (see image below)

Second option to connect a shared mailbox in Outlook:

1.  Open Outlook

2.  Click on "File" tab in the top left

3.  Account Settings  > Account Settings (see image below)

2.  Click on "New" to create a new email account

3.  Select "Email Account" and then click "Next"

4. Type the shared mailbox address into the "E-mail Address" field and leave all the other fields blank, then click "Next"

5.  When/ if the auto-discover server box pops up, check mark the "Don't ask me about this website again" and then click on "Allow"

5.  When the credentials box pops up asking for your username and password, delete the shared mailbox from the username box and type in your and personal NetID password instead.  This will authenticate your credentials and verify if you have access to this shared mailbox.  If you get a "you do not have permissions.."error message, please contact your local IT support for them to grant you access to that shared mailbox.

6. Restart Outlook

We looked at adding a mailbox in previous versions of Outlook; be sure to check out our articles for Outlook 2010 and Outlook 2013 if you are running those versions. This article will see how you can set up additional mailboxes in the latest version, Outlook 2016 (and above). It’s pretty easy.

1. To add another mailbox, launch Microsoft Outlook 2016, then click the File tab > click Info tab > Account Settings.

2. In Account Settings, select your current Mailbox and click Change.

3. On the next screen, select More Settings.

4. Select the Advanced tab and click the Add button.

5. Type in the name of the mailbox, then click OK.

6. Once the name of your mailbox is created, click Add and Apply.

7. Finish out the wizard by clicking Next, and then Finish on the Change Account screen.

8. Close out of the Account Settings screen, and then select your new mailbox in the mail pane to populate it with your messages.

Sign in to your account in Outlook on the web. For Exchange Online mailboxes, right-click Folders in the left navigation pane, and then choose Add shared folder.
