Step 1: Create a new self-signed certificate
Run the following Power Shell command (Run as Administrator):
New-SelfSignedCertificate -CertStoreLocation cert:\LocalMachine\My -DnsName *.cloud.onebox.dynamics.com -KeyUsage EncipherOnly, CRLSign, CertSign, KeyAgreement, DataEncipherment, KeyEncipherment, NonRepudiation, DigitalSignature, DecipherOnly -NotAfter (Get-Date).AddMonths(60)
Step 2: Copy the new certificate to the folder where trusted certificates are stored
Open Manage computer certificates (certlm). Newly generated certificate can be found in Personal\Certificates folder. It has the same name as the old one, but different expiration date. Now copy and paste the new certificate to the Trusted Root Certification Authorities\Certificates folder.
