Use the full email address and that mailbox’s password. The mailbox must exist on the selected service. Use the secure webmail link supplied by your service or a trusted hostname with a matching certificate; do not ignore an unexpected certificate warning.

1. From cPanel, open Email Accounts and choose Check Email beside the intended mailbox. This avoids guessing which hosted service owns the address.
2. For direct access, use the service’s HTTPS webmail URL and sign in with the full address. A common secure service port is 2096, but use the actual service link supplied for your account.
3. Open the available webmail application, commonly Roundcube. Older guides may mention removed readers such as Horde; choose only an application actually offered.
4. Inspect Inbox, Sent and Spam folders, then send a small test to an external address and reply from that address.
5. Sign out when finished, particularly on a shared device. Avoid saving mailbox credentials in a public browser.

If webmail can send and receive but a desktop client cannot, compare the client’s secure server settings and password. If webmail also fails, investigate the account, quota and routing.

A domain that recently moved may still point to another provider. Use the known service hostname and verify MX records. For a login failure, reset the mailbox password through the authorised panel rather than changing the main hosting password.
