Hello Kamal,
Thank you for contacting the Microsoft Community.
I know how important it is for you to be able to access the course materials from the Learning Download Center. Please be assured that I'm here to assist you with this current situation.
Just a heads-up: The Microsoft Learning Download Center will be retired by October. Since Microsoft is now moving to a new system, MCTs should stop using the old Learning Download Center. This also explains the access issue you encountered logging into the Learning Download Center. For now, we’ll use the interim OneDrive to distribute updated courseware until the new system is up and running. Please see this post for more information.
You can find the OneDrive link within the gated MCT Lounge - Current Courseware Downloading Process, and it's also included in your MCT Non-Disclosure Agreement. Please ensure that your access request has been granted before you can access the MCT Lounge. You can follow the instruction available on the https://aka.ms/requestmctaccess to request access or visit this sticky post.
I appreciate your patience during this transition. If you have any questions or need further assistance, feel free to reach out. I’m here to help! @Julian, thank you for sharing helpful links!
