EDIT: Think, I misread your comment and thought that you said le missed the deadline. Gonna leave this here, tho:
Is that really a bad thing tho? The fact that the deployment wouldn’t be at once was clearly stated. They got to have it deployed in 5.5 hrs tho.
Every minute won from deploying later are potentially also won for end users (especially those that use outlook) from not having that problem - and of course for their respective IT departs for renewing the cert.
