Public Folders Missing in Outlook 2016 on Windows 10 - Internal Exchange Server 2010

I have three computers running Windows 10.  One is a desktop and two are Surface Pro 3s.  All have latest windows 10 update and all have Office 365 with 2016 update.

I cracked the screen on one Surface Pro and am transferring all of my files to the new Surface Pro 3.  When I installed Office 365 and opened Outlook, I saw my normal email files, the Archive files, but no Public directories.  On my old Surface Pro 3 with the exact same configuration, I have access to all of the folders.  

My old Surface Pro 3 is still working and I have full access to all of my email folders including Public folders.

I noticed on my Desktop computer that I rarely use for email, but have the exact same configuration, I cannot see the public folders on that computer either.  I fairly recently upgraded the Office365 applications to the 2016 version.

I don't believe anyone else in the office is experiencing the same problem.  

I have rebooted the server with Exchange Server.  I had to be something related to a setting on those two computers that is keeping Outlook for seeing the public folders.

Thanks for your help.

Thank you Jackie!  Great job!

Are you aware of another solution that will allow me to use the MAPI/HTTP protocol?  

If this is the direction Microsoft is going with email, I hate to hold progress back.  Is my Exchange Server 2010 not capable of using the new protocol?  Thank you very much for your soultion.

Great Job!!
I made the addition to the registry, but that did not solve the problem!  Your explanation made a great deal of sense.

Is there another step that needs to be taken?

I made the registry correction, then rebooted the server with Exchange 2010,   That did not fix the problem so I rebooted the workstation.

Am I missing something?  I tried to follow the link in your email, but the link failed.

Thanks for your help.

Try remove and re-add the mail profile.
Thanks Jackie.  I did that and it did not help.  I am talking to Microsoft Office365 Tech support.   They are working on a solution, but the technician told me that Outlook 2016 does not support access to Exchange Server yet!!  They are suggesting that I may have to use Outlook 2013 until they fix Outlook 2016.

I have the exact same computer and configuration on a computer I have had for a year.  That computer has been updated from Windows 8.1 and Outlook 2013 from Office 365.  That computer has no problem accessing the Public folders.  

I suspect it has something to do with a fresh install.  The upgraded version of Outlook 2016 works fine.  It is the fresh install that does not.

If we find a solution, I will let you know.
By the way, they did agree with your recommendation to change:

HKEY_CURRENT_USER\Software\Microsoft\Exchange] “MapiHttpDisabled”=dword:00000001
Try to perform test connectivity ExRCA from this site using ActiveSync, Outlook Anywhere and post back your results.

Could this be the problem??
If so, where do I make a correction?
I am VERY embarrassed.

When you start Outlook, it defaults open "mail".   Folders is way down the list.  Apparently the public folder is not considered part of mail.  As a result, I saw my mail folders and the online archive, but the public folders were not there.

When I opened the "folders" link, the public folders were right there all along.

I think the public folder should be included in "mail", but at least I have solved the biggest problem.

Thanks for your help.
It is OK and I am glad that you have solved the problem. Cheers!
Just as a side comment, after I figured out My Error, I went back to the server and removed the registry entry:  HKEY_CURRENT_USER\Software\Microsoft\Exchange] “MapiHttpDisabled”=dword:00000001

I still have access to the Public Folders after rebooting the server.  Just an FYI.

Thanks again.
