Hi Imraj Sidhu
Thank you for reaching out to the Microsoft Q&A Forum.
To better understand your issue, could you please share a bit more detail:
- Did you receive any email confirming that your Microsoft 365 tenant was successfully created?
- Are you able to sign in to the Microsoft 365 Admin Center using the account you used during sign-up, or does the sign-in fail?
- Which browser and device were you using during the setup (for example, Chrome or Edge on desktop or mobile)? If possible, please also try again using an InPrivate/Incognito browser session.
Regarding error code 715-123280, this type of error is typically related to a provisioning issue during the tenant creation process. When it occurs, the setup may not complete successfully.
If the issue persists, I recommend contacting Microsoft Support by phone for further assistance: Customer service phone numbers - Microsoft Support
To connect directly with a real person, the call must include the term AdminCenter, and the role must be specified as Global Administrator. In the description of the request, the term AdminCenter must also be mentioned. During the telephone dialog, if asked about another administrator, you can answer “no.” The call will then be forwarded to a real support agent, and a service request can be created.
Please note that as a forum moderator, I do not have access to your environment or backend systems, so I’m unable to investigate this directly.
I hope this helps point you in the right direction.
