Reauthorization SunTrust Bank - Error CC-507

Thank you for reaching out on the community and telling us about your issue. I do apologize for the issue you're having. That is quite odd I'm wondering if we might need to deactivate/reactivate them so that they're reauthorized properly. I'll leave instructions down below.

First thing I'll recommend is to save a backup to revert back to just in case. You can find how to do so down below.

Next we'll try deactivating all of the accounts. You can do so by following the article listed down below.

Once all the accounts are deactivated go ahead and follow the article here on reconnecting the accounts.

Once you've done this let us know how it goes. If you're still having issues we'll see what we can try next.

Thanks,

Quicken Francisco
