A retired certification cannot be renewed after the certification retires. Microsoft states that if a certification retirement date precedes the certification expiration date, renewal must be completed before certification retirement. It also states that if a certification is retired, there is no option to renew after the certification retires.
That matches the behavior of the “Sorry, this renewal is not accessible at this time” message for retired certifications. In a similar case, the moderator guidance was: You cannot renew a retired certification.
If the certification was already retired on 31 August, renewal by 5 September is no longer available, even if the profile still shows a later expiration or a prior renewal window.
