Random users getting "no connection" with shared calendars

Question

We recently made changes to autodiscover and a new SSL cert. Although this issue has been happening before hand. It seems to be random users. Outlook 2013 and 2010. OWA works great
The olkdisc.log from an affected user shows errors:

thank you for the reply. here is the response I get:
Name                           : RAMAIL
AutoDiscoverServiceInternalUri : https://mail.domain.com/autodiscover/autodiscover.xml
When I visit the url this is what I get: I will try the rebuild next
This XML file does not appear to have any style information associated with it. The document tree is shown below.

That is expected. 
Can you create a new Outlook profile automatically? 
Unless you have full mailbox access and have auto-mapped those shared mailboxes, autodiscovery doesnt come into play here.
