Wildcard Certificate and Exchange 2016 Hybrid

Occasional Visitor

Hi team,

 

Can I use a wildcard certificate for Exchange Hybrid? I have two Exchange Servers in my environment and configured all VD URLs as mail.domain.com and autodiscover.domain.com. I'm looking at a hybrid solution. However I'm using a wildcard certifcate with *.domain.com as the CN. All IIS and SMTP services are using it. 

On my send connector, I have the FQDN as mail.domain.com.

My concern is, Can I use this with the Hybrid Configuration Wizard as well? Will it cause any issues since the certificate has *.domain.com and the FQDN is mail.domain.com. I've read at some places that this mismatch can cause issues.

 

Thank you.

RW.

Hi Roddick,

 

Yes, you can use a wildcard for Hybrid.

 

Keep in mind that is advised to use the same certificate across all Exchange Infrastructure.

Hi Nuno.

Thank you for your feedback. Is there a source on the Internet where i found something written about the use of wildcard certificates and Exchange Hybrid ?

Hi @St3fan,

 

The official doc is here https://docs.microsoft.com/en-us/exchange/certificate-requirements

 

Regarding the wildcard certificate is necessary when you can use more names. You can read more here https://docs.microsoft.com/en-us/exchange/architecture/client-access/certificates?view=exchserver-20...
