Relevant agreements are perhaps one of: 1. OP <--> Partner (confidential agreement) <--> Microsoft (MPA)[1] 2. OP <--> Microsoft (MCA)[2] 3. OP <--> Microsoft (MOSA)[3] The different types of agreements have different limitations of liability clauses. What OP wrote indicates a "partner" is involved and if this is the case, Microsoft have essentially shifted liability for fraud and billing non-payments onto the "partner"[4], who would then either wear the cost or try to shift this liability to the OP. It's not that straightforward though as any of the three parties could have a share of liability, and the "partner" would be very unlikely to want to get in a dispute with Microsoft as this would impact their other business. Liabilities are possibly also impacted by default spending limits and caps that are imposed by Microsoft on different services[5]. Allowing a $200,000 bill for one month (a 200x increase) has the appearance of being very poor financial management from the "partner" as they're potentially going to be stuck with unsecured $200,000+ liabilities from their customers if the customers became insolvent. I suppose it is possible the OP and "partner" have a bank guarantee in place to cover at least $200,000 but I'd hazard a guess they may just try to rely on an insurance policy instead to cover these rare events.
