May 2025: I have been trying to rid myself of the CC-800 error to no avail. The error happened with 2 credit cards and 1 bank account with Wellsfargo. I have fixed those. But my Schwab brokerage accounts are still a problem after dozens of different tries to fix. I went so far as to go to Schwab and turn off the Quicken connection by having it removed entirely. I deactivated all 4 accounts in Quicken. I then setup the connection again, repeatedly using different approaches. I continue to get the CC-800 error. Two accounts are traditional IRA, one account is Stock Brokerage and one account is banking checking. I have had these working fine for over 15 years. I see that in 2023 there are several entries for the CC-800 issue. To insure proper protocal, I made sure that the Schwab account names matched the Quicken names. One IRA account comes up with "create new account" rather than "link to account". Allowing this one time, did not fix the CC-800 problem. Removed all traces again and started fresh to no avail. Downloads of data due happen but still get the CC-800 error in the "One Step Update Summary." All related CC-800 problems happend just after an "update", the same day. Ver.
