Android, Active-Sync Accounts and UTM Certificates (don't play well together)

SalishSwede

I have a Samsung Galaxy S9+ (too damned expensive) and have been using it with my UTM.  The UTM certificate was installed using the User Portal so I can at least browse just fine.  The problem I have is my new mail hosting company uses Active Sync (MS Exchange Front End) to communicate with it's secure linux back end.  Back Story: I read one too many reports on how Google was selling customer data to advertisers so I removed my mail from their servers.  Anyway, I get all kinds of errors and somewhere I noticed the errors were certificate oriented and looking at the details, the certificate was the UTM's not the mail server. This looks like the browser errors did before I installed the certificate on the User Portal.  Clearly, though, it's different since at least one UTM is successfully installed on the phone.

Can someone help me understand this. 

I guess I have to install more certificates somewhere else, but no one seems to have any idea which ones or where to install them.

New Mail Hosting Company is www.kolabnow.com  They have all sorts of KB articles (mostly poorly written) but this is Sophos specific.

Thanks,

~Doug

    Hi  

    Since Exchange ActiveSync uses Port 80 and 443, It will be filtered by UTM's web protection if the source IP is in the allowed networks of a WebFilter Profile. You should get the details of the server's hostname from your service provider and create an exception for that in Web Filtering. That should possibly allow you to work without any certificate errors.
