The Extended Protection documentation https://microsoft.github.io/CSS-Exchange/Security/Extended-Protection/ is a little confusing.
It states To enable Extended Protection on Exchange Server 2013, ensure you do not have any Public Folders on Exchange Server 2013. But that is under the heading Extended Protection cannot be enabled on Exchange Server 2013 servers with Public Folders in a coexistence environment (my emphasis).
So if you only have Exchange 2013 (yes I know, hopefully we are upgrading this year) will EP still affect Public Folders?
UPDATE: Thanks to LukasSMSFT below for answering my query! We don't have a newer version of Exchange (yet!) so will either hold off enabling EP or see if we actually need any of the Public Folders we currently have.
