These instructions apply to mailboxes hosted in your cPanel account. If your email is provided through Microsoft 365, Google Workspace, or another provider, use that provider's setup instructions.
Get your mailbox settings first
In cPanel, open Email Accounts and select Connect Devices beside your email address. Copy the recommended secure incoming and outgoing settings. Use your full email address as the username and the mailbox password, which may differ from your Client Portal password.
Add the account in Outlook
- New Outlook: open Settings, then Accounts and Your accounts. Select Add Account.
- Classic Outlook: select File, then Add Account. If automatic setup does not work, select the advanced/manual setup option and choose IMAP.
Enter the server names, ports, and encryption settings supplied for your mailbox. IMAP is usually the best choice when using more than one device. For cPanel mailboxes, secure IMAP normally uses port 993 and secure SMTP normally uses port 465. Outgoing mail requires authentication with your full email address and mailbox password.
Check the connection
Send a message to an outside address and reply to it. Confirm that both messages appear where expected.
If Outlook reports a certificate error, stop and verify the secure hostname. Do not accept an invalid certificate or disable encryption. Keep the @ in your username; do not substitute a percent sign. If classic Outlook offers Secure Password Authentication (SPA), leave it off for a standard cPanel mailbox.
