To access a shared mailbox, you will need to confirm you have the access necessary with your Microsoft Administrator. Once you have that access, there are a couple of ways your shared mailbox will be available to you:

In the Microsoft Outlook Desktop Application

If you are using the Microsoft Outlook application installed on your computer, once you are signed in with your ACS or Mountain City Church email that has access to the shared mailbox, it will automatically load in Outlook once the change in access propagates down to your account. This can take a couple of hours once the change in access is applied. Try closing out of Microsoft Outlook and reopening it if it doesn't appear automatically after a few hours have passed. For more immediate access, try accessing the shared mailbox via Office.com as outlined below.

The shared mailbox will appear on the left-hand side as its own mailbox. Do be aware that notifications do not appear when new mail reaches a shared mailbox, so be diligent in checking it regularly!

Using Office.com

If you prefer to access your email via the Office.com online portal, you can also access your shared mailboxes here. To view your shared mailbox:

1. Navigate to https://www.office.com 
2. Click the red 'Sign In' button
3. Enter your ACS or Mountain City Church email address
4. Enter your password
5. On the left-hand side, in the vertical menu, click on Outlook
6. Once your email loads, in the upper right-hand corner, click on your name
7. Click on 'Open another mailbox'
8. Type the email address of the shared mailbox you wish to view
9. Click 'Open'
10. The shared mailbox will open in a new window in your browser

Here you can view and respond to emails as necessary. Do note that any actions taken in a shared mailbox impact all users that have access to that shared mailbox (for example if you delete an email in a shared mailbox, it is deleted for everyone else as well).
