Hi @Marcus,
Welcome to the Microsoft Q&A Platform! Thank you for asking your question here.
It looks that you've successfully moved a VM to a new region using Azure Resource Mover, however you're facing login issues because it's asking for Microsoft 365 credentials instead of the local admin credentials.
If you are unable to log in with the local admin credentials, you can reset the local admin password through the Azure portal>>Virtual Machine>>In the left plane-Help>>Reset Password>>Set New password>>Update.
Ensure that the VM is running and not in a stopped or deallocated state and the NSG rules associated with the VM allow RDP port numbers.
Try manually RDP with public IP of the VM and enter local admin username and password.
Review the Azure Activity Log and the VM's event logs for any errors or warnings that could offer additional insights into the login issues.
If you have any further queries, do let us know.
If the answer has been helpful, we appreciate hearing from you and would love to help others who may have the same question. Accepting answers helps increase visibility of this question for other members of the Microsoft Q&A community.
