have not chosen to trust Why Does Outlook Display a Security Warning for a Certificate Problem? When you install Exchange Server 2016 into your Active Directory environment the setup process registers a Service Connection Point (SCP) for the Autodiscover service. Autodiscover is used by client applications to discover information about Exchange mailboxes and services. For example, Outlook uses Autodiscover during the setup of a new Outlook profile to outlook certificate error exchange 2013 discover the server settings for the user, so that the profile can be automatically configured (instead of the old days of manually entering server names and other details into Outlook). By default the Autodiscover SCP is registered using a URL that includes the Exchange server's fully-qualified domain name. You can see the Autodiscover URL for an Exchange 2016 server by running the Get-ClientAccessService cmdlet in the Exchange Management Shell. For example: [PS] C:\>Get-ClientAccessService -Identity EXSERVER | Select AutodiscoverServiceInternalUri AutoDiscoverServiceInternalUri ------------------------------ https://exserver.exchange2016demo.com/Autodiscover/Autodiscover.xml Note: Previous versions of Exchange used the Get-ClientAccessServer cmdlet. With the changes in Exchange 2016 server roles architecture the new cmdlets for these management tasks are *-ClientAccessService. The old cmdlets are still available in Exchange 2016, but if you use them you will see a warning message that they are deprecated. Autodiscover is accessible via an HTTPS (SSL) connection from clients. The Exchange server also has a number of other web services that are accessible using HTTPS connections from clients, such as Exchange Web Services (EWS), Outlook on the web (also known as OWA), ActiveSync (for mobile devices), and Outlook Anywhere (used by Outlook clients). As the connection is over HTTPS the SSL certificate configured on the server must meet three criteria to

That got fixed but now your internal Outlook users are getting certificate errors! Thankfully, it's pretty easy outlook 2013 certificate error to fix. Struggling with a difficult Exchange 2010 or Exchange 2013 migration? We've learned the hard lessons so you don't have to! Contact us to get your Exchange upgraded http://exchangeserverpro.com/outlook-certificate-warning-exchange-2016/ and online. Let's assume your Exchange server is known as "exch-1.domain.local" internally but as "mail.domain.com" externally. Solution If you haven't already, you need to add your public zone ("domain.com" in this example) to your internal IP and setup a record to point "mail.domain.com" to the same IP as "exch-1.domain.local". I like using CNAMEs for this so https://www.puryear-it.com/fixing-certificate-errors-in-outlook-for-exchange-2010 you don't have to update 2 records should it ever become necessary.
