How do I replace this - can I use a sever generated certificate or do I need to buy one?

Event ID:      12016
Task Category: TransportService
Level:         Error
Keywords:      Classic
User:          N/A
Computer:      Exch01.domain.local
Description:
There is no valid SMTP Transport Layer Security (TLS) certificate for the FQDN of mail.domain.co.uk. The existing certificate for that FQDN has expired. The continued use of that FQDN will cause mail flow problems. A new certificate that contains the FQDN of mail.domain.co.uk should be installed on this server as soon as possible. You can create a new certificate by using the New-ExchangeCertificate task.
