Office365 Outlook Account Redirected to cpanlmaildiscovery

I changed my IMH DNS settings (MX, CName,SRV) settings so my email would be redirected to my Office365 account in December 2015 - all worked well. I added an account to my desktop Outlook and was receiving my email as desired. Everything was syncing properly. This week an issue occurred where I was unable to open my desktop outlook as I was receiving notice that my email account was redirected to https://cpanelmaildiscovery.cpanel.net/autodiscover/autodiscover.xml. I was prompted to allow this website to configure my server settings. I clicked Allow... bad move as I was no longer able even to open Outlook on my desktop. I'm using Outlook 2016 which requires autodiscover to operate, if not, you're hooped. Unfortunately I have several email accounts coming into my Outlook. The message I was getting was "Outlook cannot log you on. Verify you are connected to the network and are using the proper server and mailbox name. The Microsoft Exchange information service in your profile is missing required information. Modify your profile to ensure you are using the correct Microsoft Exchange information Service". When OK was clicked on this popup, another appeared stating "Cannot open Microsoft Outlook. Cannot open the Outlook window. The set of folders cannot be opened. The information store could not be opened" I managed to remove all the local .PST files on my computer and through this process re-set up my personal email (ISP) but am unable to create a new account in Outlook for my business mail. When I attempt to add my business account Outlook does not get past "Searching for settings". I believe this problem originated in my Cpanel where some setting over-rode my Office365 settings and prompted a change to DNS settings. I can still get my business email "inside" Office365 but cannot set up my Desktop Outlook to download my email to desktop. Can you help me with this?
