I cannot subscribe to Microsoft 365 Business Basic (No Teams) on a monthly plan

Question

Error code is 715-123280.

It occured after I provided my business details (just before entering billing details).

I have tried different emails (not associated with another Microsoft 365 setup), incognito, switch different browsers, change to a different network.

I have tried other plans (including free trials and even paid ones) but still no luck.

Dear @ICT Bhawikarsu,

Thank you for coming back and for confirming what happened when you contacted Microsoft Support.

I completely understand your frustration. To be honest, I have received similar feedback from several users who were trying to reach the correct support team, and I have personally tested the process myself. During those tests, I encountered a very similar experience where I was repeatedly directed to links or automated prompts across multiple calls before eventually reaching the appropriate support flow.

Unfortunately, this part of the process sometimes requires more patience than it should. However, based on what you described, your experience is very similar to what I observed during my own testing.

One thing that may help is to slightly adjust how you answer the automated questions, so the system routes you to the correct queue more quickly. For example:

Support Bot: Education or company account? You: Company account. Support Bot: What issue are you experiencing? You: Microsoft Authenticator / I cannot sign in to my administrator account. Support Bot: What Microsoft product are you using? You: Microsoft 365 Business Basic. Support Bot: Are you an administrator? You: Yes. Support Bot: Are there any other administrators in your organization? You: No. Support Bot: Would you like to open a new support case or discuss an existing one? You: Open a new support case. Support Bot: Is the issue related to being locked out of or unable to sign in to an account? You: Yes.

If the system repeats certain questions, I encourage you to continue answering consistently and patiently.

Once you reach the stage where a case can be opened, please be prepared to provide the exact email address you are using. The support team may send you a verification email or future case communications through that address, so it is important that the email address is provided accurately. They may also ask for your domain name during the verification process.

Most importantly, if you are able to obtain a ticket number, please come back and share it here. While I cannot access Microsoft's internal systems, I can help review the information with you, point you toward the appropriate support path, and hopefully help ensure the case reaches the team best equipped to investigate the provisioning failure and Error Code 715-123280.

I sincerely hope you are able to get past the automated routing step and reach a support agent who can investigate this further. Please keep me updated on your progress, and I will be happy to help however I can.

Thank you and have a great day!

Please understand that this is a public community forum. In my role as a community moderator, I do not have access to Microsoft’s subscription provisioning systems, billing platform, backend logs, or account registration services, so I cannot investigate the error directly or determine the exact cause of Error Code 715-123280. However, I will do my best to help point you in the right direction.

Dear @ICT Bhawikarsu,

I hope you’re having a good day.

Thank you for reaching out and for providing both the screenshot and the detailed troubleshooting information.

Based on your description, the issue is not limited to a specific Microsoft 365 plan and persists across multiple signup attempts, this appears less likely to be a browser-side issue and more likely to require investigation by Microsoft's subscription or commerce systems.

I recommend contacting Microsoft Support and providing the details from the error screen along with the screenshot you attached.

Since the issue occurs before a subscription or tenant can be successfully created, opening a support request from a Microsoft 365 Admin Center may not be possible in this scenario. Support may need to review the provisioning process associated with the Event ID and SID shown on the error page.

You can contact Microsoft through: Microsoft Customer Service Phone Numbers

(Depending on your country or region, when you call the support number, you may hear an introduction of about 30 seconds such as "you can visit the link...". You can ignore this introduction and wait until you are presented with the options. Then press "1" as a business email user, and again "1" for technical help)

When contacting them, I would recommend explaining that:

The subscription signup process fails before billing details are entered, affects multiple trial and paid offers, and returns Error Code 715-123280 together with an Event ID and SID.

Thank you again for the detailed troubleshooting you have already performed, it helps rule out many of the common causes.

I hope you're able to connect with the appropriate team and get the subscription provisioning issue resolved quickly. If you receive any additional information or a response from support, please feel free to share it here and I'll be happy to help review it further.

Thank you and have a great day!

Warm regards,
