ActiveSync certificate

Hello there was a question about ActiveSync and NetBios name in the certificate

Here is an example of what I'm doing.

There are Exchange 2013 with the name "Exmail"

All virtual directories are configured:

Internal: https://mail.domain.com

External: https://mail.domai.com

Issue certificates on https://www.wosign.com service certificate specifies the names

1. mail.domain.com

2. Autodiscover.mail.domain.com

All is well connected except ActiveSync do the test using Test-ActiveSyncConnectivity | fl

He says the certificate is invalid.

[System.Net.WebException]: The underlying connection was closed: Could not establis
trust relationship for the SSL / TLS secure channel. Inner error
[System.Security.Authentication.AuthenticationException]: The remote certificate is
invalid according to the validation procedure.

Not sure if I will release an additional certificate with the name of SAN ServerCAS.localdomain mistake and ActiveSync will take work. But I want that record 2, it was stated in the certificate. Articles in Google darkness, but I do not like will not understand what to do that would earn ActiveSync SAN with two names. Will it work with the two above mentioned names or be sure to add the NetBios name of the server that the CAS would have turned 3 entries in the certificate?

1. mail.domain.com

2. Autodiscover.mail.domain.kom

3. Exmaill.LocalDomail.local
