I have an on premises exchange 2013 setup, and I am trying to have a hybrid setup between office 365 and this on premises. But when I try to create a migration endpoint, it says that the connection to server could not be completed.

Technet doc says I need to enable MRS Proxy Service, but I can't see such an option.

Even if I try to enable hybrid, I am recieving the following errors:

Can someone please help me where I am going wrong @ the earliest. Thanks in advance.

Notice that in addition to the cert validation issue, it looks like DNS for Autodiscover might be off. – Todd Wilcox Jul 1 at 12:35
@ToddWilcox: Do you mean that we need to have a specific server in the name and have a dns for this.? – serverstackqns Jul 1 at 12:48
Look at your own images: "Attempting to locate SRV record _autodiscover._tcp.<domain>.com in DNS". You have to fix all of these problems for Autodiscover, ActiveSync, and hybrid migrations to work. – Todd Wilcox Jul 1 at 12:51

You have to have ActiveSync and possibly AutoDiscover working for the on-premise organization in order to do a hybrid coexistence migration. Use the Microsoft Remote Connectivity Analyzer to check that Exchange ActiveSync and AutoDiscover are working. A common problem here is not having the correct certificates installed correctly.

Thanks! We've tried using a self signed cert, but the errors posted above. Since this is a POC, we don't want to pay for certificate. Can you please let me know if there's any other alternative to this issue.? – serverstackqns Jul 1 at 12:27
As far as I have been able to tell, there is no way to successfully hybrid without purchasing a cert, and not just any cert, I think you have to get a UC cert. I've tried it with a wildcard cert and had trouble. – Todd Wilcox Jul 1 at 12:34
Thanks. But why we are not able to setup migration endpoint? Any idea – serverstackqns Jul 1 at 12:47
You have to have a cert signed by a recognized CA. Look at the actual error messages in the images you added to your answer. – Todd Wilcox Jul 1 at 12:50
