       So, seems like Microsoft's *.olc.protection.outlook.com mail servers are currently using certificates signed by an distrusted root CA[1].That seems like a shocking level of incompetence.It means that any mail server supporting MTA-STS is currently unable to deliver any mail to them.[1] DigiCert Global Root CA which has been scheduled for distrusting since 2023 https://knowledge.digicert.com/general-information/digicert-root-and-intermediate-ca-certificate-updates-2023

       Affected recipient domains include hotmail.com, live.com and outlook.com, but also various other customer domains, eg. deutschebahn.com

       I don't suppose anyone here knows the best way to notify them of this problem? Anyone with contacts at Microsoft?

       @pfefferle @mellifluousbox If they think it's ok to skimp on their marketing material budget, what else do they think it's not worth paying for? 🤔

       @pfefferle @mellifluousbox To put my thought another way: if they think AI art is "good enough", what else (hygiene, health and safety) do they think is "good enough" too?

       @pfefferle @mellifluousbox A fair counterpoint. Depends heavily how long they've been in business.
