Hello @Arunas Bucevicius,
I truly apologize for the misunderstanding regarding the issue.
We have identified the administrator account that was created when the tenant was initially set up, which uses the onmicrosoft domain. Due to forum policy, we are unable to disclose any personal information or provide explicit details. I have sent you a private message so that I can assist you in gaining access to the domain.
Greatly appreciate again for your patience and understanding. Looking forward to your response.
