Connecting Custom Domain Email to Microsoft Outlook
Fix 'Something went wrong' and manually configure IMAP & SMTP securely in Microsoft Outlook.
Instructions
Open Outlook & Choose Manual Setup
Launch Microsoft Outlook. Enter your full business email address (e.g., [email protected]). Click on 'Advanced options' and check the box 'Let me set up my account manually', then click Connect. IMPORTANT: Do not click Connect without checking manual setup, or Outlook will attempt Exchange Autodiscover and fail with 'Something went wrong'.
Select IMAP Account Type
From the list of account types (Office 365, Outlook.com, Google, POP, IMAP), click on 'IMAP'. IMAP ensures your emails, folders, and read statuses sync seamlessly across your PC, phone, and webmail.
Configure Incoming & Outgoing Mail Servers
Enter the following exact hostnames and ports. Hostname must strictly be core.mailasia.in (do not use mail.yourdomain.com to prevent SSL certificate name mismatch errors):

[Outgoing Mail (SMTP)]

Encryption method: SSL/TLS or STARTTLS
Require logon using Secure Password Authentication (SPA): [UNCHECKED / OFF]
Outgoing server requires authentication: [CHECKED / ON - Same as incoming]Enter Mailbox Password & Complete Setup
Enter the password you created for this mailbox in the HostAsia Mail Control Panel. Click Connect. Outlook will verify the credentials and display 'Account successfully added'.
