Wildcard Certificate and Exchange 2016 Hybrid
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-2019
