How to create public folders

Problem:

You need to manually enable public folders in Exchange Server 2010, 2013, 2016 or Exchange Online (Office 365).

Solution:

To enable public folders, you have to create an empty public folder tree. If you are using CodeTwo Exchange Migration or CodeTwo Office 365 Migration, the exact tree structure and content of the public folders from your old Exchange server will be automatically recreated in this new tree.

Exchange Server 2013, 2016, and Exchange Online (Office 365)

Follow the steps below to enable public folders in Exchange Server 2013, Exchange Server 2016 or Exchange Online (Office 365). By following these guidelines, you will create an empty public folder tree. Note that the screenshots in this article are from Exchange Server 2013, but the settings described here look almost the same in Exchange Online (Office 365) and Exchange Server 2016.

1. Log in to your Exchange:
   • Exchange Server 2013, 2016 - log in to the Exchange Control Panel (ECP) using your domain admin account. If you are accessing Exchange Server directly, the address is https://localhost/ecp
   • Exchange Online (Office 365) - log in to the Microsoft 365 admin center (Office 365 admin center) using your Office 365 global administrator account, and open Exchange admin center (use the menu to navigate to Admin centers > Exchange).
2. Go to the public folders section (Fig. 1.).
