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?
