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 and I'm looking at a hybrid solution. However I'm using a wildcard certifcate with * as the CN. All IIS and SMTP services are using it. 

On my send connector, I have the FQDN as

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


Thank you.

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.
