Email, Adding Additional Account to Outlook

Adding an Additional Mailbox to Outlook

Learn how to add an additional shared mailbox or resource account to Outlook. These instructions cover Classic Outlook, New Outlook, and Outlook on the Web.

Before You Begin

Before adding a shared mailbox, make sure you have the necessary permissions to access it. This includes mailboxes for which you have been granted Full Access (FA), either directly or through an Active Directory (AD) security group.

• You must have Full Access permissions to the mailbox.
• You will need the mailbox name or email address.
• Allow time for newly granted permissions to take effect before attempting to add the mailbox.

Instructions

Option 1: Classic Outlook (Desktop)

Use these instructions to add an additional mailbox to the Classic Outlook desktop application.

1. Open Outlook (Classic).
2. Select File.
3. Select Account Settings, then select Account Settings again.
4. Under the Email tab, select your primary account (your NetID@illinois.edu address).
5. Select Change.
6. Select More Settings.
7. Open the Advanced tab.
8. Under Mailboxes, select Add.
9. Enter the name of the shared mailbox or resource account.
10. Select OK.
11. Select Next, then select Finish.
12. Select Close to exit Account Settings.

The additional mailbox should now appear in your Outlook folder list. You may need to restart Outlook for the changes to appear.

Option 2: Outlook on the Web

Use these instructions to access an additional mailbox through a web browser.

1. Open a web browser and navigate to Outlook on the Web.
2. Sign in using your University email account if prompted.

4. Right-click Folders and select Add shared folder or mailbox.
5. Enter the shared mailbox name or email address.
6. Select the mailbox when it appears in the search results, or select Open as prompted.

The shared mailbox should now appear in your folder list. You can expand it to access its folders and messages.

Option 3: New Outlook (Desktop)

Use these instructions to add a shared mailbox in the New Outlook application.

1. Open Outlook (New).
2. In the left navigation pane, expand your primary mailbox (your NetID@illinois.edu address).
3. Locate and select Shared with me.
4. Check whether the desired shared mailbox is already listed. If it is, the mailbox is accessible and no further steps are needed.
5. If the mailbox is not listed, select the three dots (...) next to Shared with me.
6. Enter the shared mailbox name or email address.
7. Select Add.

The shared mailbox should now appear under Shared with me in the navigation pane.

Additional Information

• These instructions also apply to resource mailboxes accessed through an assigned Full Access (FA) Active Directory group.
• Full Access permissions allow you to open and manage the mailbox. Send As permissions are separate and must be granted independently.
• Adding a mailbox to Outlook does not automatically grant additional permissions.
