To anyone who is having trouble with Schwab - if you are getting CC-501 or CC-506 errors - the problem could be happening to you if you have more than one log on. For instance, I have a Schwab log on and so does my husband. Quicken started sending me error messages on 7/15/2024 and has not corrected itself since. What seems to be the problem (after calling Quicken support twice) is that the server Schwab uses cannot support more than one log in connection to Quicken at a time. In my family, we actually have THREE log ins for something like 11 accounts. Two accounts are not connecting regularly, and I have to reauthorize/reset several accounts every day. It seems almost random when it works and when it doesn't. The problem is the server Schwab is using. Other vendors, such as Fidelity, Bank of America, Amex, etc. use a different server so can support more than one log on per Quicken File. As FYI, even when creating a separate file for each Schwab user log on I occasionally get the same error messages. Come on Quicken and Schwab you can make this work for your mutual clients!
