Adding an additional or shared mailbox from the same Exchange organization to Outlook

I’ve been granted access to a shared mailbox on our Exchange sever. For this, I’ve been given the name and email address of the mailbox but I didn’t get a password for it.

When I try to add the account, Outlook already resolves my current name and email address. While I can change this, it then also asks for the password which I don’t have.

How am I supposed to access this mailbox?

Add Exchange mailbox buttonThis is one of those issues which is easier to solve than you might think. However, your Exchange administrator must have granted “Full Access” permissions for that mailbox to your account for you to be able to add it as an Exchange account.

As an alternative, you might be able to add it as an additional mailbox rather than an additional account.

Either way, you should be able to do this without knowing the password for that mailbox.

Note 1: Contact the mailbox owner or your Exchange administrator if you are unsure about which permissions you have been granted for the mailbox.

Note 2: Adding a mailbox as an additional Exchange account is only possible in Outlook 2010, Outlook 2013 and Outlook 2016. When you use Outlook 2007 or previous, you can still add it as an additional mailbox.

Add as an additional Exchange account

When you go through the account setup, Auto Account Setup may indeed already fill in your current username and e-mail address.

In that case, when you change the e-mail address field, you’ll see a “Password” and “Retype Password” field appear.

Filling out these fields is only required when you actually want to log on with the account which holds that email address. When you have been granted “Full Access” permissions to the mailbox, you can actually log on with your own credentials.

To do this, simply don’t fill out anything in these fields but click “Next” instead.

Auto Account Setup will now look up the server details and once it has found them, it will prompt you for your user credentials. You can now fill out your own username and password.

Depending on how your domain has been configured, you must specify your username in one of the following formats:

When prompted for credentials, fill out your own username and password instead of credentials of the shared mailbox itself.
When prompted for credentials, fill out your own username and password instead of credentials of the shared mailbox itself.

When you indeed had been granted “Full Access” permissions to the mailbox, the account configuration will be successful and the mailbox will be added to your account list and Folder List.

Note: When you have been granted “Full Access” permissions to the mailbox but your administrator has also enabled the “Automapping” property for it, then the mailbox might have been added as a “hidden” additional mailbox already. In that case see: Can’t remove additional Exchange mailboxes

Add as an additional Exchange mailbox

When you don’t have been granted “Full Access” permissions to the mailbox by your Exchange administrator, you might only have been granted “Folder-level” or “Delegate” permissions by the mailbox owner.

In that case, you can add the mailbox to your Outlook configuration without password in the following way:

  1. Open the Account Properties dialog:
    • Outlook 2003
      Tools-> E-mail Accounts…
    • Outlook 2007
      Tools-> Account Settings…
    • Outlook 2010, Outlook 2013 and Outlook 2016
      File-> section Info-> Account Settings-> Account Settings…
  2. Double click on your Exchange account to open its properties.
  3. Click on the button: More Settings…
  4. Select the Advanced tab.
  5. Click on the button: Add…
  6. Type the name or the email address of the mailbox which you’d like to access.
  7. Confirm all the open dialogs to return back to Outlook.

The mailbox should now be added to your Folder List.

Via your Exchange account properties, you can add a shared mailbox as an additional mailbox rather than an additional Exchange account.

Note: If you can’t expand the mailbox, you haven’t be granted the correct permissions by the mailbox owner. Most likely you haven’t been granted the “Folder visible” permission on the top level folder of the mailbox itself (important!) and/or any of the subfolders which you are allowed to access. Once the permissions issue has been solved, restart Outlook and you should be able to open the mailbox.
