Unexpected ₹147K Claude charges despite active Microsoft for Startups sponsorship
Hi Microsoft for Startups team and community, I am a Microsoft for Startups participant using an Azure Sponsorship subscription. I recently discovered unexpected charges from Anthropic Claude through Microsoft Foundry. The Claude usage was billed as Marketplace/SaaS charges instead of being deducted from my Microsoft for Startups Azure sponsorship credits. My Azure Sponsorship credit is still active and has a substantial unused balance. However, my Azure Cost Analysis currently shows approximately ₹491K in September charges, with approximately ₹475K categorized as SaaS, primarily related to Claude. I currently have an invoice amount of approximately ₹147K due. I stopped the Claude deployments as soon as I discovered the charges to prevent further usage. I contacted Azure Billing Support multiple times, but the requests were closed with a message saying that the issue falls outside Billing and Subscription Support because it involves Marketplace/third-party services. I was directed to Marketplace refund resources instead. I also tried to contact Microsoft for Startups support. I was previously instructed by the Microsoft for Startups team to use the Founders Hub support portal, but my account now redirects to the newer Microsoft for Startups experience in Azure, where I cannot find the documented startup program support option. I need help getting this escalated to the appropriate Microsoft for Startups or Marketplace team for an actual review. Specifically, I would like to know: What is the correct support channel for this situation? Can Microsoft review the unexpected Claude charges? Is a discretionary credit, refund, or billing adjustment possible given the circumstances? I can provide screenshots showing my active sponsorship, remaining Azure credits, Claude charges, and invoice privately if required. Thank you.
$17,493 in Undisclosed Marketplace Charges with No Cost Visibility, No Recourse, No Accountability
I'm a co-founder of a 13-person startup in the Microsoft for Startups Founders Hub program. I'm posting here because after two months of support tickets, calls, and emails across both Microsoft and Anthropic, I have been unable to get anyone with decision-making authority to address this issue. I'm hoping this reaches someone at Microsoft who can help, and that other affected founders in the program will share their experiences. What happened: In February 2026, we deployed Claude Opus 4.6 and Sonnet 4.6 through Azure AI Foundry as part of a migration of our AI infrastructure. We are active users of our Azure sponsorship credits and assumed, as anyone would, that these models were covered the same way Azure OpenAI models are. There was no indication otherwise during deployment. In early March, we received our first invoice: $1,078.07 (invoice G144899694, billing period 02/01–02/28). We were shocked, but we paid it immediately and removed all Anthropic model deployments from our account to prevent further charges. It didn't matter. On April 9, we received a second invoice: $16,414.94 (invoice G151890529, billing period 03/01–03/31). Despite removing the deployments in mid-March, charges had already accumulated for the first half of the month. We are unable to pay this invoice. Our total exposure across both invoices is $17,493.01. Why we had no way to prevent this: No billing distinction at deployment. Azure AI Foundry presents all models (Microsoft-native and third-party) in the same unified interface. There is no warning, label, or confirmation step indicating that certain models are excluded from sponsorship credits. No cost visibility whatsoever. The Azure AI Foundry monitoring dashboard has an "Estimated Cost" section that is completely blank for these models, with a disclaimer: "Cost monitoring is available for Foundry Models sold directly by Azure only." We could see token counts but had zero visibility into what we were being charged. Token counts that don't explain the charges. The dashboards show our Claude Opus 4.6 deployment used 63.4M tokens and our Sonnet 4.6 deployments used roughly 170M tokens combined. At published rates, that should be in the low thousands, not $17,500. My analysis shows the dashboard hides billions of cached tokens (prompt caching reads and writes) that are invisible in the monitoring UI but account for the vast majority of the bill. There is no view in Azure that provides a breakdown of these charges by token type. No alerts or notifications. There were no cost alerts, no threshold warnings, and no notifications at any point. No indication in any Azure portal that charges were hitting our credit card. There was no line item, no pending charge, no Marketplace spend summary - nothing anywhere in the Azure ecosystem that showed dollars accumulating against our payment method for these deployments. What happened when we asked for help: Azure Support (TrackingID#2603090040002936): After a month-long wait, a support engineer told us Microsoft cannot issue credits for Marketplace charges and directed us to Anthropic. The first version of the response email referenced "Azure DDoS Protection Standard" instead of our actual issue, suggesting the volume of similar cases in the queue. Anthropic: Their AI support bot responded within one minute with a blanket statement and closed the ticket four hours later. I escalated, but have still not received a response over a month later. Microsoft for Startups Team (TrackingID#2604070040009778): Told us they cannot apply Marketplace charges against sponsorship credits and referred us to a Marketplace billing contact. Azure Marketplace billing contact: Pending response. The pattern is clear: Microsoft directs us to Anthropic. Anthropic directs us to Microsoft. The Microsoft for Startups team directs us to Azure Marketplace billing. No one takes responsibility. What I'm asking for: A full refund of $17,493.01 across invoices G144899694 and G151890529 That Microsoft implement clear billing warnings in Azure AI Foundry before deploying models that are excluded from sponsorship credits. That Microsoft provide actual cost visibility in the monitoring dashboard for all models deployed through AI Foundry, not just first-party models. To other founders in the program: If you have experienced this same issue, please reply to this thread. I know I'm not alone because this has been covered by The Register, InfoWorld, and Computerworld, and at least 20 founders have signed a Change.org petition about it. The more founders who come forward with specific amounts and case numbers, the harder this is to ignore. We joined Microsoft for Startups because the program was supposed to help early-stage companies manage infrastructure costs during the most financially vulnerable period of our growth. Instead, the program's own platform generated charges within 2 weeks that exceed the total sponsorship credits we've consumed over the past year, with no visibility, no warning, and no path to resolution.

Thumbnails in Explorer.exe Using Up Significant Memory
It seems that there is an issue with explorer with storing thumbnail cache for folders containing 6k to 8k resolution videos. For context, I keep virtual reality videos in one folder and every single time I open this folder and browse through all other files and sub folders, the memory usage for explorer spikes up. I need help on how to fix this issue. Any workarounds such as storing thumbnail cache on the drive instead of the RAM would help. I'm using Windows 10 22H2
Microsoft for Startups: wait it out or cut my losses?
I’ve spent months in Microsoft for Startups, and I’m frustrated enough to question whether continuing is worth it. I’d appreciate advice from founders who have navigated its credit milestones. Here’s the timeline: - August: Support told us we had seven qualifying workloads. We planned our Azure usage around that guidance. Microsoft later confirmed that information was wrong: only three resources had exceeded $1 in consumption that month. - September: Azure Cost Management showed eight workloads with more than $1 in consumption, but Support reported five qualifying workloads, with the required 60-consecutive-day qualification period starting September 11, 2026. They have not explained the difference between those counts, nor the start date which doesn't match when the resources went live. - Now: Under the corrected timeline, we expect to run out of existing credits before reaching the next milestone. I requested a program-manager review and a way to submit formal feedback about the incorrect guidance and its impact. I still haven’t heard back. After months in the program, nobody has been able to give us a clear, account-specific explanation of which workloads count, which don’t, or why the qualification count differs from what we see in Cost Management. I understand that spending more than $1 may not be the only requirement—but what additional requirements are our workloads failing? The repeated explanation is that progression is automated and Support cannot override it. “It’s automated” does not explain the calculation or address the consequences of incorrect support advice. I’m not upset that credits come with conditions. I’m upset that we relied on incorrect information, cannot independently verify our progress, and are spending time chasing basic explanations instead of building the business. At this point, I would struggle to recommend the program to another founder. Has anyone successfully resolved a situation like this? Would you wait it out to see whether the next credits materialize, potentially spending your own money in the meantime—or consider this a failed experiment, cut your losses, and move on?
How can a Microsoft for Startups user escalate unexpected Claude Marketplace billing?
I have approximately ₹9.49 lakh of Microsoft for Startups Azure credits remaining. I deployed Anthropic Claude through Microsoft Foundry and later received invoice G183537293 for ₹70,716.76 because the Claude Marketplace usage was not covered by the sponsorship credits. I understand the eligibility rule now. My question is about escalation. Azure Billing has told me Marketplace adjustments are handled by the publisher. Anthropic has told me Azure Marketplace billing is processed through Microsoft. I have therefore been redirected between both parties. I also found a previous Microsoft for Startups case involving similar unintended Claude/Foundry usage where the customer reported receiving a $1,000 special-exception credit: https://learn.microsoft.com/en-us/answers/questions/5728641/azure-ai-foundry-presents-third-party-ai-models-as?utm_source=chatgpt.com Is there a Microsoft for Startups, Marketplace billing, or Foundry escalation team authorized to review a one-time goodwill credit in this situation? I am specifically looking for the correct escalation path, not asking the Q&A community to access or modify my invoice.
Startup verification failed for newly incorporated company - records now synced, need manual review
Hi team, I need a manual review of my Azure startup credit business verification. The automated check returned "We couldn't verify your startup. We'll switch you to a pay-as-you-go subscription once your remaining Azure credits run out or expire." No reason was given, and there is no option to resubmit. Context: - Company: I entered the legal name exactly as on the Certificate of Incorporation. The company was incorporated in India on 30 Sep 2026. - I submitted the business details on the same day I received the Certificate of Incorporation. Because the company had just been incorporated, its records had not yet reached public databases at that time. - Those records have now synced. The CIN and PAN can both be verified, and the company bank account is being opened. - I'm a genuine early-stage startup. Support history: - Emailed email address removed for privacy reasons on 1 Oct 2026: no response - Azure support ticket 2610030030000809, opened 4 Oct 2026: no response Every listed Microsoft for Startups support link redirects back to the Azure portal, so I can't find another channel. My current credit expires in 30 days, so this is time-sensitive: I need to decide whether to continue building my startup on Azure. Request: please escalate to the startup credits verification team for a manual review. I can share the company details, documents (Certificate of Incorporation, PAN, TAN), subscription ID and any other details privately. Thank you.Azure Startup Credit Issue
Hi, I've been trying to verify my LinkedIn account to unlock $1,000 in Azure startup credits for over a week. Every time the OAuth callback hits error and, I get: {"error":{"code":"BadRequest","message":"BadRequest (Conflict)"}}. I've revoked all LinkedIn app permissions on both LinkedIn and Microsoft sides. I suspect that the issue is an orphaned LinkedIn identity record in your backend from a previous failed attempt. My support ticket has gone unanswered for over a week now and I also created a post in the learn community that went unanswered for days now. Could you point me to the right person? Happy to provide any account details needed.
No Decision After 7 Working Days + Portal Loop Issue – Rain Stella Technology
Hi Microsoft for Startups Community & Team, I am following up on my Microsoft for Startups application submitted on behalf of Rain Stella Technology, and would also like to flag a portal issue I experienced after the application was submitted. --- Application Status --- I received a confirmation email acknowledging receipt of my application, however it has now been 7 working days with no further communication — no approval, no decline, and no request for additional information. According to Microsoft's own guidelines, applications are typically reviewed within 3 business days. We are now more than double that timeframe with no update. Application Details: • Applicant Name: Khalid Adine • Startup Name: Rain Stella Technology • Status: Receipt confirmation received, no decision communicated since • Days Elapsed: 7 working days --- Portal Issue --- During and after submitting my application, I encountered a frustrating portal bug where, instead of displaying a confirmation screen or application status, the portal kept redirecting me back to the "Apply Now" screen — as if my submission had not been recorded. I received the receipt confirmation email, which confirmed the application went through, but the portal still does not reflect any application status. This caused significant confusion, and I wanted to flag it in case it is a widely known issue affecting other applicants. I also attempted to contact support via email (email address removed for privacy reasons), but the address returned a bounce error, leaving the forum and contact form as my only available channels. --- My Requests --- 1. Can someone from the team confirm the current status of our application? 2. Is any additional information or documentation required from our side? 3. Can the portal loop bug be investigated and fixed for other applicants facing the same issue? 4. What is the correct and currently working support email or channel for urgent queries? We are actively building our product and are eager to move forward with the program. Any update would be sincerely appreciated. Thank you for your time and support. Khalid Adine Founder, Rain Stella Technology
