Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
Hello Alexander88,
Good day! Thank you for posting to Microsoft Community. We are happy to assist you.
The Microsoft Customer Agreement (MCA) is a new agreement that consolidates the terms and conditions for Microsoft's commercial cloud services into one agreement. It is designed to be more flexible and easier to understand than previous agreements. The MCA applies to all customers who purchase commercial cloud services directly from Microsoft, including Microsoft 365 and Office 365. MCA is for new offer.
The Microsoft Online Service Agreement (MOSA) is an older agreement that applies to customers who purchased commercial cloud services prior to the introduction of the MCA. It is still in effect for those customers, but Microsoft is encouraging them to transition to the MCA. MOSA for old legacy offer
In terms of billing account details, the main difference between the two agreements is the legal terms and conditions that govern the use of Microsoft's commercial cloud services. The MCA is the more current and comprehensive agreement, while the MOSA is an older agreement that is being phased out. Please refer this: From MOSA to the Microsoft Customer Agreement
