Contact Microsoft Support for Billing and Subscription Assistance
Because this issue is tied directly to Microsoft's backend billing systems and product availability, it requires intervention from a live Microsoft support agent.
Community support forums and standard troubleshooting steps, such as clearing your browser cache or switching browsers, will not resolve account-specific billing errors. A Microsoft support representative must investigate your subscription status and manually facilitate the storage upgrade.
Open your web browser and go to the official Microsoft Support contact page at https://support.microsoft.com/en-us/home/contact.
Type 'Product does not exist OneDrive storage' or 'OneDrive billing error' into the search box and click the 'Get Help' button.
Scroll to the bottom of the help articles provided and click the 'Contact Support' button.
Under 'Products and services', choose 'Microsoft 365 and Office'. Under 'Category', select 'Manage My Subscription'. Click 'Confirm' to proceed.
Select 'Chat with a support agent in your web browser'. If prompted, verify your Microsoft account credentials to begin the chat.

Frequently Asked Questions
Why does Microsoft say the OneDrive storage product does not exist?
This error typically occurs due to a synchronization glitch in Microsoft's billing system, an outdated browser cache affecting the Microsoft Store cart, or when a specific storage tier is temporarily unavailable for purchase in your region.
Will clearing my browser cache fix the OneDrive purchase crash?
While clearing your browser cache or trying an Incognito/Private window is a good first step to rule out local browser conflicts, it usually does not fix this specific error because the 'Product does not exist' message is tied to backend subscription management.
What is the maximum additional OneDrive storage I can purchase?
Microsoft currently allows Microsoft 365 Personal and Family subscribers to add up to 1 TB of additional OneDrive storage in increments, bringing the maximum total cloud storage to 2 TB per user.
