Outlook setup (Windows, Mac, Mobile)

Overview​

This guide covers configuring Clearbox mailboxes in Outlook for Windows, Outlook for Mac, and the Outlook mobile app. It includes automatic setup tips (Autodiscover), manual IMAP/SMTP settings, port numbers, and troubleshooting.

  • IMAP (incoming): clearbox.alfrolia.com — port 993 (SSL/TLS)
  • SMTP (outgoing): clearbox.alfrolia.com — port 587 (STARTTLS) (or 465 for SMTPS)
  • Username: full email address
  • Authentication: password or app password (OAuth is not supported). Clearbox provides built-in TLS/SSL for secure connections.

Outlook for Windows (modern versions)​

  1. File → Add Account → Enter your email address.
  2. If Outlook finds your settings automatically (Autodiscover), follow the prompts and sign in with your account password when requested.
  3. If automatic setup fails: choose Manual setup → select IMAP and enter the server settings above.
  4. Test the connection and finish.

Notes for Outlook on Windows​

  • Autodiscover may use the domain’s DNS records; ensure your domain's DNS is pointed and verified if using Autodiscover.
  • Outlook supports app passwords for accounts with 2FA; use an app password if needed.
  • Check the Sent and Drafts folder mapping if messages don't appear where expected.

Outlook for Mac​

  1. Outlook → Tools → Accounts → Add Email Account.
  2. Enter your email; if automatic setup fails, choose Not Exchange? then IMAP/POP and enter the settings above.
  3. Confirm server port settings and authentication.

Outlook mobile (iOS & Android)​

  1. Open Outlook app → Settings → Add Account → Add Email Account.
  2. Enter email and choose IMAP if manual setup is needed, otherwise sign in with your account password.
  3. Enter server details if prompted.

Troubleshooting​

  • Authentication failures: try app passwords if your account uses 2FA.
  • Certificate errors: check that the server hostname matches the certificate and TLS is enabled.
  • Sync issues: verify connection status, and ensure mailbox sync window and folder mappings are set correctly in Outlook settings.

Advanced Outlook tips​

  • Use the latest Outlook version to benefit from Autodiscover improvements and general compatibility.
  • When migrating from Exchange or another provider, allow Outlook to rebuild local caches (OST) after reconnecting.
