Microsoft Outlook can send and receive the email included with your Domain India hosting plan, as long as the server name, ports, encryption, username and outgoing authentication are right. Outlook tries to find these settings on its own and often picks the wrong ones, so this guide shows the manual setup for each current version of Outlook, and how to fix an account that won't connect or won't send.
Add the account as IMAP and set it up manually. Incoming: mail.yourdomain.com, port 993, SSL/TLS. Outgoing: mail.yourdomain.com, port 465, SSL/TLS, with "My outgoing server (SMTP) requires authentication" on. The username is your full email address and the password is the mailbox password. Leave "Secure Password Authentication (SPA)" unticked. Business Email has its own settings guide.
1. Check which email you have
These steps are for mailboxes you created in cPanel, DirectAdmin, Webuzo or Plesk as part of a Domain India hosting plan.
Domain India Business Email is a separate product with its own servers. It is IMAP only (no POP3), and its webmail is at https://mail.yourdomain.com:8443/. If that is what you have, use setting up Outlook, Apple Mail and your phone for Business Email instead. Not sure which you have? See Business Email vs the email included with your hosting.
2. The settings Outlook needs
Replace yourdomain.com with your own domain. These ports were measured open on our shared servers on 20 September 2026.
| Setting | cPanel, DirectAdmin and Webuzo | Windows (Plesk) hosting |
|---|---|---|
| Account type | IMAP (recommended) | IMAP (recommended) |
| Incoming server and port | mail.yourdomain.com, 993, SSL/TLS | mail.yourdomain.com, 993, SSL/TLS |
| Outgoing server and port | mail.yourdomain.com, 465, SSL/TLS | mail.yourdomain.com, 465, SSL/TLS |
| Outgoing alternative | 587, STARTTLS | None: port 587 is closed |
| POP3 instead of IMAP | 995, SSL/TLS | 995, SSL/TLS |
| Username | Your full email address | Your full email address |
| Outgoing authentication | Required, same as incoming | Required, same as incoming |
- Password: the mailbox password you set when you created the address, not your control panel or client area password. You can change it in your panel; see managing your email accounts.
- Ports and encryption are pairs. 993, 995 and 465 go with SSL/TLS. 587 goes with STARTTLS. Mixing them, for example 465 with STARTTLS, is the most common reason a new account won't connect.
- SPA: leave "Require logon using Secure Password Authentication (SPA)" unticked for both servers. Our servers use normal password login over an encrypted connection.
In cPanel, open Email › Email Accounts and click Connect Devices next to the address. It lists the server names and ports for that account. If Outlook shows a certificate warning for mail.yourdomain.com, use the server name from that page instead.
3. Classic Outlook for Windows
Classic Outlook is the version in Microsoft 365, Outlook 2024 and 2021. Older versions such as 2019 and 2016 use the same steps but are no longer supported by Microsoft, so update if you can.
- Add the account.Go to File › Add Account.
- Choose manual setup.Enter your full email address, open Advanced options, tick Let me set up my account manually, and click Connect.
- Choose IMAP.On the account type screen, choose IMAP.
- Enter the incoming settings.Server
mail.yourdomain.com, port 993, encryption method SSL/TLS. Leave SPA unticked. - Enter the outgoing settings.Server
mail.yourdomain.com, port 465, encryption method SSL/TLS. Leave SPA unticked. Click Next. - Enter the mailbox passwordand click Connect, then Done.
Now send yourself a test message. If it arrives but replies won't send, see section 6.
4. The new Outlook for Windows
The new Outlook replaces Mail and Calendar on Windows 11 and can be switched on from classic Outlook.
- Open account settings.Go to Settings › Accounts › Email accounts and choose Add account.
- Enter your full email addressand continue. If Outlook asks for the provider or account type, choose IMAP.
- Open the advanced settings.If Outlook tries to set things up on its own, choose the option to enter the server settings yourself.
- Fill in both servers.Incoming
mail.yourdomain.com, port 993, SSL/TLS. Outgoingmail.yourdomain.com, port 465, SSL/TLS. Use your full email address as the username for both, with the mailbox password. - Continue and finish.Send a test message to check both directions.
Microsoft changes the new Outlook's screens often. If the words differ, look for "IMAP", "advanced" or "server settings".
5. Outlook for Mac and Outlook on your phone
Outlook for Mac: go to Outlook › Settings › Accounts, click + and choose New Account. Enter your email address, and when asked for the provider, choose IMAP/POP. Select IMAP as the type, enter your full email address and password, then set the incoming server to mail.yourdomain.com on port 993 and the outgoing server to mail.yourdomain.com on port 465, with the SSL option ticked for both.
Outlook on iPhone or Android: tap Add account, enter your email address, and choose to set up the account manually. Pick IMAP, open the advanced settings, and enter mail.yourdomain.com with your full email address and password for both the incoming (IMAP) and outgoing (SMTP) server. If the app lets you set ports, use 993 and 465.
6. Fix an account that won't send or connect
In classic Outlook, go to File › Account Settings › Account Settings, select the account and click Change. Depending on your version, the server settings open directly, or you click More Settings:
- On the Outgoing Server tab, tick My outgoing server (SMTP) requires authentication and choose Use same settings as my incoming mail server. Outlook doesn't always set this, and without it mail arrives but never sends.
- On the Advanced tab, check the ports and encryption against section 2.
| What you see | Likely cause | Fix |
|---|---|---|
| Password keeps being asked for or rejected | Username is not the full address, or an old password | Use [email protected]; test the password in webmail |
| Receives but won't send | Outgoing authentication is off | Turn on "requires authentication" as above |
| Sending times out | Wrong port, or your network blocks it | Use 465 with SSL/TLS; try from mobile data |
| Certificate warning | Server name doesn't match the certificate | Use the server name from cPanel's Connect Devices page |
| Works on mobile data, fails on office Wi-Fi | That network's IP address is blocked after failed logins | Update the password on every device, then contact support with your public IP address |
Test the mailbox in webmail first: if the password works there, the problem is in Outlook. Webmail addresses are in how to log in to webmail. For more sending problems, see I can receive mail but I cannot send it.
A phone or laptop that keeps trying an old password causes repeated failed logins, and the server firewall then blocks that IP address, cutting off mail for everyone on the same connection. After changing a mailbox password, update it on every device.
7. IMAP or POP3 in Outlook?
Choose IMAP. It keeps your mail on the server, so Outlook, your phone and webmail all show the same inbox, and nothing is lost if a computer fails. POP3 downloads mail into one Outlook data file. If you must use POP3, keep Leave a copy of messages on the server ticked on the Advanced tab. See IMAP vs POP3: which to choose.
8. Limits worth knowing
- Sending: 200 messages per hour per account on cPanel hosting and 1,000 per day on DirectAdmin. See do you limit the amount of mail I can send.
- Message size: up to 100 MB on cPanel and 50 MB on DirectAdmin, including attachments. The recipient's provider often accepts far less, so send a link for large files.
9. Where Domain India fits
Every Domain India cPanel, DirectAdmin and Webuzo hosting plan includes email accounts at your domain, and all of them work in Outlook with the settings above. If you want mail that runs separately from your website, with calendar and contacts, Business Email is priced per mailbox, starting with one:
- Priced per mailbox - start with one
- Email at your own domain ([email protected])
- Add and remove mailboxes yourself
- Webmail with calendar, contacts and tasks
The price on the card is a Domain India list price and excludes 18% GST.
Frequently asked questions
What are the Outlook settings for Domain India hosting email?
Choose IMAP. Incoming server mail.yourdomain.com on port 993 with SSL/TLS, outgoing server mail.yourdomain.com on port 465 with SSL/TLS, your full email address as the username, and outgoing authentication turned on with the same details.
Why can Outlook receive email but not send it?
Usually "My outgoing server (SMTP) requires authentication" is off. Open the account's settings, turn it on with "Use same settings as my incoming mail server", and check the outgoing port is 465 with SSL/TLS.
Should I tick Secure Password Authentication (SPA) in Outlook?
No. Leave SPA unticked for both the incoming and outgoing servers. Domain India hosting mail uses normal password login over an encrypted SSL/TLS connection.
Can I use port 587 in Outlook?
Yes on cPanel, DirectAdmin and Webuzo hosting, with STARTTLS encryption. Port 587 is closed on Windows (Plesk) hosting, so use 465 with SSL/TLS there.
What username do I use in Outlook?
Your full email address, for example [email protected], with the mailbox password you set in your control panel. It is not your control panel or client area password.
Do these settings work for Domain India Business Email?
Not entirely. Business Email is a separate product that supports IMAP only, with no POP3. Use the Business Email client setup guide for its settings.
Ready to set up your other devices? The email client settings guide covers Apple Mail, Thunderbird, iPhone and Android with the same settings. If Outlook still won't connect, open a ticket in the client area or use the public ticket form.
