How to Troubleshoot Authentication Errors with Mac OS Mail and Zoho Mail

Are you experiencing authentication errors while trying to set up your Zoho Mail account on your Mac OS Mail client? If so, this article is here to help you troubleshoot the issue.

To start, check the Outgoing Port Number and SSL settings in your Mail preferences. Go to Mail > Preferences > Accounts > Outgoing Mail Server (SMTP) > Edit SMTP Server list. Ensure that SSL is turned on for the SMTP server and the Outgoing Port Number is correct.

Next, check if the port number is correct by going to Mail > Preferences > Accounts > Advanced. Verify that SSL is turned on for Incoming Server and the port number is 993. Additionally, make sure that the Incoming and SMTP Server names are correct.

Often, connection errors occur when the server details are incorrect. If you're experiencing issues, contact your email administrator for assistance.

If you're part of an organization, your administrator may have restricted access via IMAP to your account. In this case, generate and use an Application Specific Password if you have Two Factor Authentication enabled.

Check if you have Two Factor Authentication turned on. If IMAP Status is disabled, enable IMAP and try again. If you continue to experience authentication errors, check your IMAP Status.

To set up your Zoho Mail account in Apple Mail, follow these steps:

1. Go to Mail > Accounts > Click the + icon in the bottom right corner to add a new account.

2. Select Other Mail Account, skipping the default options provided.

3. Specify your preferred Display Name, Email Address of your account in Zoho, and password.

4. Choose the Incoming and Outgoing server details as follows:

Incoming Mail Server: imap.zohomail.com (for personal users) or imap.zohomail.com (for organization users who have their domains hosted with Zoho Mail).

Password: Zoho account password (you may require an Application Specific password if Two Factor Authentication is enabled for your account).

User Name: Your complete email address.

5. Click Sign In and provide the configuration details manually.

6. Make sure that IMAP Access is enabled in the Zoho Mail interface by going to Settings > Mail Accounts > IMAP Access and clicking the checkbox.

For best results, ensure that you have a good internet connection when configuring your account.

By following these steps, you should be able to troubleshoot any authentication errors and successfully set up your Zoho Mail account on your Mac OS Mail client.
