Turning on automatic renewals for a certificate
You can turn on automatic certificate renewals for these types of certificates:
TLS/SSL (Basic and Business)
Standard Code Signing
Client
Private SSL
Grid
Once the feature has been turned on, 30 days before the certificate expires, it will be automatically renewed.
Exceptions
EV code signing and document signing certificates do not support automatic renewals. The auto-renew feature is also disabled for certificate orders that were paid for with a credit card.
