Capital One Accounts in Quicken for Mac: 351 Error
You may receive a 351 Error when attempting to update your Capital One accounts in Quicken for Mac. This occurs because Capital One has changed the connection method for their accounts in Quicken. You will need to re-authorize your accounts to connect through this new method.
Before you begin: If you have multiple Capital One accounts
Quicken is moving to this new experience with all of Capital One's financial institutions, and this means you'll need to authorize your accounts for each Capital One financial institution individually.
For example, if you have a checking account with Capital One 360, and a credit card account with Capital One - Credit Cards, you would need to go through the process twice, one for each financial institution. Don't worry–Quicken will prompt you if you need to go through the process more than once.
If you do need to go through the migration process more than once, it's important that you don't uncheck any accounts listed on the authorization screen, unless you don't want to see the account at all in Quicken:
If you uncheck accounts during the process, this will revoke your authorization, and prevent the accounts from updating. If you've unchecked accounts, you can just follow this FAQ for Windows, or this FAQ for Mac, to authorize them again for download into Quicken.
NOTE: if you have multiple accounts with just one Capital One financial institution, you'll only need to go through the process once.
