Owner cannot create modern public folders by using Outlook in Exchange Server 2013 or Exchange Server 2016

View products that this article applies to.

Symptoms

Assume that you are the owner of a public folder mailbox or have sufficient access permissions to create a public folder in a Microsoft Exchange Server 2013 or Microsoft Exchange Server 2016 environment. The mailbox uses the secondary hierarchy as the default public folder mailbox. In this situation, when you try to create a public folder by using Microsoft Outlook, you receive the following error message:
Cannot create the folder. You do not have sufficient permission to perform this operation on this object.
See the folder contact or your system administrator.

Note If the default public folder mailbox is changed to a public folder mailbox that contains the primary hierarchy, you can create public folders by using Outlook.

See More information about how to troubleshoot the issue in this article.
