Before you can start delivering public folders to your customers you must prepare your environment by following a few simple steps.

The first step is to create the first public folder mailbox. The first public folder mailbox created is the Master and all other ones created after are secondary. The hierarchy will always be contained within the master but the actual content will be contained within the customers public folder mailbox.

Create the first public folder mailbox:

• Select Public Folders
• Select Public Folder Mailboxes
• Click on the Add button

There are a couple of requirements that need to be met for the master public folder mailbox:

• This mailbox must always be available or people will not be able to write to their public folders
• This mailbox must contain a valid email address which contains a domain that works with autodiscover for all customers. (You may need to use powershell to set this email address)
