XGS 2100: Certificate Authority: Invalid or Not Installed

Graboid$

Hi Team,

I uploaded a new PositiveSSL Cert (mail.company.com) for our Exchange On-premise email and I am getting an error "Certificate Authority: Invalid or Not Installed"

We have a wildcard certificate (*.company.com) and it was recently renewed and the upload was successful.

Both certificates were uploaded using.pfx format as Sophos XGS firewall does not support .cer.

Both .cer certificate was installed on our Exchange Onpremise Server and exported as a .pfx format.

However, with mail.company.com cert, I am getting the invalid error.

Thank you.
