How do I disconnect my msol service?

As a cryptocurrency and finance professional, I'm often asked technical questions regarding various services. One such inquiry I've encountered recently is: "How do I safely disconnect my Microsoft Online Services (MSOL) account from my financial portfolio or crypto wallet? Given the sensitivity of financial data, it's crucial to ensure the process is secure and thorough. Could you walk me through the necessary steps to fully disassociate MSOL from my financial applications?" This question highlights the importance of maintaining data security and privacy, especially when dealing with finances and cryptocurrencies.
