Outlook 2016 (non-domain PC) will not connect to Exchange 2010 server!!

hi guys

We have set up Office 365 for around 5 users in our organisation. These users already have an Exchange 2010 mailbox.  We have done the necessary in the Microsoft portal. These PC's are based in a non-domain environment and they now have Office 365 installed. So Outlook 2016 no longer has the ability to connect via RPC over HTTP!!

So the other option is to set up the user on Office 365 via Outlook but when I enter their email address and go to 'Next' it prompts for the password of this email account. I enter it and i get a 'an encrypted connection to your mail server is not available. Click Next to attempt using an unencrypted connection'.

Any ideas guys how to resolve this issue and get Outlook 2016 connecting?

Thanks for helping

If user had office 365 license that includes office suit then try activating the Office applications like Word/Excel with the user.
Then try configuring outlook.
If it did not worked try configuring outlook using http://www.config365.com/.

Outlook 2016 DOES support RPC/HTTP, they are only removing support on the server side in Exchange Online. It will not affect any on-premises installations. You have some other underlying issue, try checking the results from the ExRCA here: https://testconnectivity.microsoft.com/
