### Notes

- You may need to restart Outlook after adding the new mailbox.
- When adding a shared mailbox, if you are prompted for any credentials enter y*our A-State credentials*.
- If you have permissions to custom folders in the mailbox but not to the top-level mailbox folder, the custom folders will not appear in the folder list. Only default folders that you have permissions to, such as Inbox, Sent Items, Deleted Items, and Calendar, will appear in the folder list without top-level mailbox folder permissions.
