Share Mailbox Folders (Step #1) - Mailbox Owner
With this method, access to an Additional Mailbox is granted by the Owner of that Mailbox. This access can be provisioned by having the owner right-click (or control-click) the account in Outlook, and selecting "Sharing Permissions...". Any other user can be added, and given the exact level of permissions required.
Please note that you will need to do the following to any sub-folders within the account, including the Inbox and Deleted Items. Mailbox Owners must share their Mail Account, Inbox, and Deleted Items with Folder Visible Permissions at a minimum. This will ensure that Subfolders of the Inbox can be used. You do not need to grant Read, Delete, or Write Permissions to your Inbox, but Deleted Items will require Visible and Create Permissions.
