Good morning Jimmy,
Im afraid that you don't understand the situation here. WE are telling YOU, that YOUR deployment server is broken, that YOUR supply chain is broken or possibly under attack (a file on your servers was changed after being signed, and that server might distribute malware to your customers). All your alarm bells should ring loud and you should report this immediately to the responsible teams.
Instead, you are sending us on a "permit A-38 quest" as if we were Asterix and Obelix.
So yeah, we can file support tickets at our IT departments, who may raise a support ticket at Microsoft when they find the time, and we can go on twiddling thumbs while some evildoers are comfortably taking over your servers and lash down another terrible security incident on your company. But hey, who am I to tell you how to do your job?
So which path will we take?
Best
Andreas
