Apple Mail App - Duplicate iCloud accounts
For some reason when I first set up my Mail account on my Mac, it shows duplicate mailboxes for the same iCloud account. Two sets of everything. The mailboxes sync properly. I receive emails, but I am unable to send email to send any emails. I receive this message when I attempt to send any emails: The server response was: <unknown[68.207.114.63]>: Client host rejected: Access denied
I am running the most recent update of macOS Sonoma 14.0
I am able to send and receive email on the Mail app from my other apple devices.
I have tried disabling iCloud Mail and reenabling. This is tedious because it re-downloads thousands of messages. And it didn't help.
I have tried signing entirely out of iCloud and back in. This is tedious because the Mac wants to delete all my local iCloud Drive files, Photo Library, etc, and then re-sync. Didn't help.
Has anyone found a solution for the double iCloud account in mail issue please?
