Outlook 2016 login to a Mailbox of Exchange 2016, but it won' t access the Public Folders of Exchange 2010

Exchange 2010 and Exchange 2016 Coexistence. Some users' mailbox have moved to Exchange 2016 from 2010. the company Public Folders still in Exchange 2010. those users are able to access the public folders of exchange 2010 by using outlook 2013, but outlook 2016.
as I know, Outlook 2016 access exchange 2016 server by using MAPI over HTTP. after I did disable the MAPI over HTTP in regedit, and force to use RPC over HTTP, the public folder showed up in outlook 2016, but it was unable to open.
is there anything I need to do next?

First thing to do is disable mapi on the 2016 server, run this on the 2016 exchange powershell.

Set-OrganizationConfig -MapiHttpEnabled $false running this will switch all outlook 2016 clients to use rpc instead of mapi without the registry change. This may fix the public folder issue but I would then migrate the public folders to 2016. Full details here.

Thank you Dave. I did run the command: Set-OrganizationConfig -MapiHttpEnabled $false. after I relogin to the outlook,  the outlook connection status showed protocol: HTTP. it is not RPC over HTTP.

Are you able to migrate the public folders to 2016?

Which clients support public folders?

Outlook 2010 and later, and Outlook 2011 for Mac users can access public folders. However, users whose mailboxes are on Exchange 2016 servers won’t be able to connect to Exchange 2010 public folders from clients that use Exchange Web Services (EWS), such as Outlook for Mac. We recommend that you migrate legacy public folders to Exchange 2016 in order to maintain access for those users.
