Certificate requirement of hybrid Exchange 2016 and Online RRS feed

  • Question

  • Hello Experts,

    I'm requesting certificate for the hybrid setup.  In case in the future there will be new names needed in the certificate. I was thinking if i could use wildcard cert. like *.companyname.com 

    I didn't find much information regarding wildcard cert for hybrid Exchange. Would you please tell me the answer. If we can use wildcard cert.  how to generate a CSR in Exchange.

  • Hi TianChen,

    Yes, you can use a wildcard cert in a Hybrid environment.

    Please refer to the following article to request a wildcard cert:

    Create an Exchange 2016 certificate request for a certification authority

    Moreover, when using a wildcard cert, you may run into an issue with Exchange Hybrid Migration Wizard, there is an workaround for your reference:

    Wild Card Certificates and Hybrid Configuration Wizard

    Hope this helps,

    Best Regards,
