Hi Mike,
Thank you for contacting the Microsoft Community.
I understand how difficult it can be when you're unable to access the materials you need for an upcoming training, especially when time is of the essence. I'm here to help you with this issue.
Indeed, recent changes to Microsoft compliance and security requirements have affected the Learning Download Center’s functionality, necessitating an immediate replacement. The error message you're experiencing is because the Microsoft Learning Download Center has been retired, a process that began last September and continued through October.
To guarantee that MCTs maintain uninterrupted access to Microsoft Courseware during the LDC replacement, the Publication Team has transferred all courseware to the interim OneDrive solution. To make it more convenient for you, please refer to the response I have left in the private message I initiated.
The OneDrive interim solution will serve as the courseware distribution tool until the replacement courseware distribution system is launched. Having said this, we recommend staying tuned to new articles posted on our MCT Program Announcements blog about updates on this system replacements process and important dates.
If you are having difficulties accessing the MCT Lounge, you will need to add this platform to your Microsoft Tech Community profile. Please confirm you are signed in to the Microsoft Tech Community using the email address linked to your MCT status. Then, you will need to request access to this secured site. You can follow the steps outlined on this page: MCT Lounge Access Request process.
We greatly appreciate your ongoing patience and cooperation as we work through these system issues impacting our MCT community. If you need further assistance, please let me know.
I look forward to your response. Please note that if no response is received after two business days, the case will be closed and locked. After the case is locked, we will no longer be able to respond, even through Private Messages.
