Unable to upgrade Microsoft 365 Business Basic to Business Standard or purchase a new licence

Jack Bridge 0

Hello,

I currently have a Microsoft 365 Business Basic (no Teams) subscription and need to upgrade to Microsoft 365 Business Standard so that I can use the desktop Microsoft applications, including Outlook for Mac.

However, whenever I attempt to upgrade the existing subscription, the Microsoft 365 Admin Centre produces an error and will not allow me to complete the purchase.

"Sorry, there was an error processing your request. Please try again later."

Microsoft Support suggested that I purchase a separate Business Standard subscription, assign the new licences to my users and then cancel the existing Business Basic subscription. However, I cannot purchase the new Business Standard subscription separately either, as the purchase process also fails.

To clarify:

My existing Business Basic subscription is active.
Payments for the existing subscription appear to be processing successfully.
I cannot upgrade from Business Basic to Business Standard.
I cannot purchase Business Standard as a separate new subscription.
I do not want to cancel my existing licences first and risk losing access to emails, mailboxes or company services.
I have contacted Microsoft Support several times, but the issue has not yet been resolved.

Has anyone experienced this issue before?

Is there another way to purchase or manually upgrade the licences without cancelling the existing subscription first? Can Microsoft Support process the licence change manually from their side?

Any advice would be greatly appreciated.

Hi @Jack Bridge,

Based on what you've described, this sounds more like a billing or subscription provisioning issue on the Microsoft 365 tenant side. Since you're unable to both upgrade the existing subscription and purchase a new one, I believe this is something that needs to be investigated by Microsoft Support, as they have the necessary tools and access to identify and resolve the issue efficiently.

I would not recommend cancelling your existing Business Basic subscription first, as doing so could potentially cause service disruption and create unnecessary risk for your users.

You mentioned that you've contacted Microsoft Support several times but the issue has not yet been resolved. May I ask which support channel you've been using (phone, chat, support ticket)?

If you haven't already done so, I believe the best next step is to open a support ticket directly from the Microsoft 365 Admin Center > Help & Support.

Tips: You can switch off the Support Assistant as shown in the screenshot, then type a few short characters into the search box and select Get Help. After that, wait for the Contact Support button to appear and click it. At the final step, be sure to clearly describe your request in the description fields so the support engineers can quickly understand your issue and assist you more effectively.

Once the ticket is created, a Microsoft support engineer can investigate the issue from the backend using tools and permissions that are not available to community members here. This allows them to identify the root cause and provide the most appropriate resolution.

If you've already created a support ticket but haven't received a response yet, or if the case doesn't seem to be moving forward, please let me know. I'll be happy to help explore other options and provide further guidance within the scope.

Looking forward to your response.

Hi Rin,

Thank you for your response. So far, you are honestly the only person who has explained the situation in a way that makes sense. :)

I have opened multiple support tickets directly through the Microsoft 365 Admin Centre, so the people contacting me are genuinely from Microsoft Support. Unfortunately, I am still no closer to resolving the issue.

I have been passed between several different support engineers, with nobody appearing to take ownership of the case. One engineer asked me to install Fiddler, reproduce the payment error and collect diagnostic logs for Microsoft. Another offered to arrange a remote session, but after I confirmed my availability, I received no further response.

I understand that diagnostic information may sometimes be necessary, but this is becoming extremely frustrating. I do not feel that I should need to install specialist diagnostic software and investigate Microsoft’s billing system on their behalf just to upgrade a license.

Thank you again for your help and for confirming that cancelling the existing subscription first would not be advisable. I really appreciate you taking the time to respond.

Hi @Jack Bridge,

Thank you for the update, and for your kind words. They are truly appreciated.

Based on what you've shared, if the support team is asking you to install Fiddler and collect diagnostic logs, that's probably a required step in their troubleshooting process for this particular case. I know it can feel a bit unreasonable, but I'd still encourage you to cooperate with those requests if possible. In many cases, the engineering team relies on those logs to pinpoint exactly where things are failing and move the investigation forward.

If you find that you've been waiting a long time for an update, you may want to escalate the case through the existing support ticket. Typically, the email communications from Microsoft Support include contact details in the signature block for related team members, managers, or escalation contacts. You can consider sending a polite follow-up email to those contacts, referencing your case number and requesting an update on the status of the investigation.

Of course, this is just my personal opinion and experience from seeing similar situations. I can't directly influence the case or make it move faster, unfortunately. However, I sincerely hope you're able to get this resolved quickly so you can stop spending time and energy chasing it.

Please feel free to keep me posted if there are any updates. Thank you for your patience.
