Now I thought I would give Microsoft support a chance with this one, but ... yeah ... Anyway I am getting a "certificate not valid" on my mobile devices office 365 autodiscover scp when trying to connect to our Office 365 Exchange. Exchange Online. Whatever one wants office 365 autodiscover internal dns to call it! When I run the autodiscover test, I get the following (mydomain.com is a fake, obviously): Host name mydomain.com doesn't office 365 autodiscover hybrid match any name found on the server certificate CN=sni.dreamhost.com, O=DreamHost, C=US. We host that domain at Dreamhost. I am assuming that I need a SSL certificate somewhere, but am a little unsure as to where, exactly. https://support.microsoft.com/en-us/kb/2772058 Has anyone ever been through this before?

And then THAT is where the error message comes up. But I also get a autodiscover SSL error on the Microsoft testing page, so I know something is amiss. 0 Chipotle OP Alan Byrne Jun 3, 2015 at 9:22 UTC Are you running a hybrid setup or are all your users on Office 365? If all your users are on Office 365 then you should create (or replace) your CName Autodiscover record and have it point to autodiscover.outlook.com More information can be found here: https://support.office.com/en-gb/article/External-Domain-Name-System-records-for-Office-365-c0531a6f... 0 Anaheim OP BRRABill Jun 3, 2015 at 9:23 UTC Our CNAME does indeed point there. I think it's a certificate issue. 0 Mace OP LarryG. Jun 3, 2015 at 9:53 UTC If I am reading this correctly... You shouldn't need one. That's handled by the MS servers. Something is pointing your phone to the wrong place, which is why you are seeing this. 1 Anaheim OP BRRABill Jun 3, 2015 at 10:07 UTC When I run the Microsoft Exchange ActiveSync Connectivity Test from Microsoft's own servers is when that error message comes up.

Example of an Outlook certificate warning The two most common problems reported by the Outlook certificate warning message office 365 are: The name on the security certificate is invalid or does not match the name of the site The security certificate was issued by a company you 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 office 365 autodiscover 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 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
GUI for installing a SSL Certificate. Because Office 365 is designed to run on Microsoft IIS, you can use IIS to install your certificate. If you have not yet created a Certificate Signing Request (CSR) and ordered your certificate, see Microsoft Office 365: SSL Certificate CSR Creation (IIS). The installation process consists of two steps: installing the certificate on the server and assigning/binding the certificate the default website. IIS 8/8.5 or IIS 7 If you used IIS to create your CSR, you need to use IIS to install the certificate and then, to assign/bind the certificate to the default website (HTTPS port 443) For IIS 8/8.5 instructions, see Office 365: How to Install Your SSL Certificate Using IIS 8/8.5. For IIS 7 instructions, see Office 365: How to Install Your SSL Certificate Using IIS 7. DigiCert Certificate Utility If you used the DigiCert Certificate Utility for Windows to generate your CSR, you need to use the DigiCert Certificate Utility to import/install your SSL Certificate. Then, you need to use IIS to assign/bind the certificate to the default website (HTTPS port 443). Install your SSL Certificate. See SSL Certificate Importing Instructions: DigiCert Certificate Utility for Windows. Assign your SSL Certificate. To assign/bind the certificate to the default website (HTTPS port 443): For IIS 8/8.5 instructions, see Using IIS 8/8.5 to Assign the Certificate to the Default Website. For IIS 7 instructions, see Using IIS 7 to Assign the Certificate to the Default Website. Office 365: How to Install Your SSL Certificate Using IIS 8/8.5 Using IIS 8/8.5 to Install the SSL Certificate After DigiCert validates and issues your SSL Certificate, you can use IIS to install your SSL Certificate to the server where you generated the CSR. Then, you can use IIS to bind the certificate to the default website (HTTPS port 443). Open the ZIP file containing your SSL Certificate and save the SSL Certificate file (your_domain_name.cer) to the desktop of your AD FS server. Open Internet Information Services (IIS) Manager. From the Start screen, type and click Internet Information Services (IIS) Manager. In Internet Information Services (IIS) Manager, under Connections, select your server’s Hostname. In the center menu, in the IIS section, double-click the Server Certificates icon. In the Actions menu, click Complete Certificate Request to open the Complete Request Certificate wizard.
