Exchange 2013 - Certificate Errors

Posted on 2016-09-30

I have server 2012 R2 installed with Hyper-V; one VM "2012 R2" with essential experience as the DC; one VM with Exchange 2013.
Mail is working well with OWA and Outlook.  But I have two issues:

On outlook, after connecting, we get a certificate error "The name on the security certificate is invalid or does not match the name of the site" on all clients (except one).
    What do I need to check, verify etc. ?

I cannot get "Anywhere Access" to complete on the DC server.  I am trying to use the SSL certificate issued for the Exchange which it accepts.
    Should the intermediate certificate be installed on this server ?
    Is it correct to use this SSL certificate on the DC server ?

Use this to look at the specifics on your certificates.

Get-ExchangeCertificate | fl

Did you get your cert from a CA like Godaddy?

Make sure it hasn't expired.

Spent some time this morning cross checking all settings using -MAS-'s article as guidance.

Current situation:  The SSL certificate is from Godaddy and has over 18 months to run.  It is assigned to services IMAP, POP, SMTP and IIS and the hosts   remote.   autodiscover.    mail.   and  servername.   are assigned.

We get certificate errors on all  'Outlook 2013'  clients  but,  the  'Outlook 2016'  client works correctly.

We also get a certificate error on using the ECP interface.

Hope the  'Outlook 2016'  gives you a clue !

Regards

Problems using Powershell and Active Directory?

Managing Active Directory does not always have to be complicated.  If you are spending more time trying instead of doing, then it's time to look at something else. For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why

It's the Certificate Security Warning

"The name of the security certificate is invalid or does not match the name of the site"

displayed about 2 minutes after opening Outlook
