How to import a Wildcard SSL Certificate in Exchange 2013

You can place the cert in the appropriate location, Run the below command

Import-ExchangeCertificate -FileData ([Byte[]]$(Get-Content -Path "C:\cert\Certfile.pfx" -Encoding byte -ReadCount 0)) |Enable-ExchangeCertificate -Services IIS, POP, IMAP


Note : You cannot do this via EAC ( Exchange Admin Center)

You got to configure Imap and pop using Set-Popsettings and Set-Imap Settings

as Wild Card cert doesn’t have a complete FQDN entry

To Configure IMAP and POP

  1. Hi Satheshwaran,

    Your tip is very good!

    I have an Exchange 2013 with a valid certificate and will expire next month.
    I have too a SSL certificate (public and private keys) and I convert to PFX format.
    I use the PowerShell command to verify: “Import-ExchangeCertificate -FileData ([Byte[]]$(Get-Content -Path “C:\cert.pfx” -Encoding byte -ReadCount 0)) |Enable-ExchangeCertificate -Services SMTP, IIS, POP, IMAP”
    The return was ok to my wildcard domain.

    Can I use your tip to import my wildcard ssl certificate in PFX format?

    Thanks a lot.
