We’ve been using Azure for a few months now so it’s about time our certificates would expire right? Well according to the email notification we’ve just received a certificate needs updating or we’ll lose access!
In order to provide your organization with uninterrupted access to Office 365 and Microsoft Azure Active Directory (Azure AD), you need to ensure your certificate for the domain(s) domain.tld is renewed and updated in Azure AD right away.
Our current certificate on file for domain(s) domain.tld expires on 5/5/2018.
If you don’t take action, your users will lose access on this date or, in the default configuration of Active Directory Federation Services, 15 days prior to 5/5/2018.
What you should do right now
If you are using AD FS with the default configuration, or are using a third party STS or a non-default configuration of AD FS, follow the article here.
