Apple Mail is not working in MacBook Pro

Here are the troubleshooting steps:

1. Ensure MacBook Pro has an active internet connection for email retrieval.
2. Confirm correct server settings (incoming/outgoing mail servers, ports, SSL) from provider.
3. Uncheck "Take All Accounts Offline" in Mailbox menu to enable online mode.
4. Quit and reopen Apple Mail to resolve temporary connectivity issues.
5. Reboot the MacBook Pro to potentially resolve application and connectivity problems.
6. Ensure correct password entry; incorrect passwords prevent email account synchronization.
7. Confirm no service outages or maintenance affecting email provider’s operations.
8. Temporarily disable firewall or security software to check for interference with email.
9. Install the latest macOS updates to fix bugs and improve application functionality.
10. Delete and recreate the email account in Apple Mail for troubleshooting purposes.

Any of these separately listed email providers (except Other) requires you to check their checkbox and use the included 'complex setup' that may have extra steps with a Web Browser window.

In addition, if you are using such a 'complex setup' AND running Sonoma, additional additional steps may be required. Readers can advise if you ask.

I'm sorry to hear that Apple Mail isn't working on your MacBook Pro. To help you troubleshoot, could you provide more details about the issue you're experiencing? Are you seeing any error messages, or is the application not opening at all?

Is this your Apple ID? Or another iCloud account?

Do you have any VPN software installed? If so, turn it off.
