Setting up your Ultra Web Hosting email in Microsoft Outlook takes about 5 minutes. This guide covers Outlook for Windows (365, 2021, 2019, 2016) with step-by-step instructions. We recommend IMAP over POP3 because it syncs your email across all devices. You'll need your email address, password, and server hostname.
Your Outlook Settings
Use your server hostname for both incoming and outgoing servers. Find it in your client area under service details.
- ✓ Incoming (IMAP): yourserver.ultrawebhosting.com, Port 993, SSL/TLS
- ✓ Outgoing (SMTP): yourserver.ultrawebhosting.com, Port 465, SSL/TLS
- ✓ Username: your full email address
- ✓ Authentication: Normal password (not OAuth2)
01. What You'll Need
Gather these before starting:
- Server hostname - looks like
web150.ultrawebhosting.com. Find it in your client area under your hosting service details - Email address - the full address you want to set up (e.g.,
info@yourdomain.com) - Email password - the password set in cPanel > Email Accounts. This is not your cPanel login password
If you don't know your email password, you can reset it in cPanel > Email Accounts without affecting any existing email messages.
02. Automatic Setup (Outlook 365/2021)
Newer versions of Outlook try to auto-configure email accounts. This sometimes works with cPanel-hosted email, but often picks the wrong settings. Here's the process:
- Open Outlook - go to File > Add Account
- Enter your email address - type the full address and click Connect
- If prompted for account type - select IMAP
- Enter your password - use the email account password from cPanel
- If it connects - verify the settings match Section 5 below
If Outlook shows a "Sign in with your browser" prompt or tries OAuth2 authentication, cancel and use the manual setup in Section 3 instead. Our servers use traditional password authentication, not Microsoft's Modern Authentication / OAuth2.
03. Manual IMAP Setup
This is the most reliable method and works with all Outlook versions.
Outlook 365 / 2021 / 2019
- File > Add Account - enter your email address
- Click "Advanced options" - check "Let me set up my account manually," then click Connect
- Select IMAP - from the account type options
- Incoming mail settings:
- Server:
yourserver.ultrawebhosting.com - Port:
993 - Encryption method: SSL/TLS
- Server:
- Outgoing mail settings:
- Server:
yourserver.ultrawebhosting.com - Port:
465 - Encryption method: SSL/TLS
- Server:
- Enter your password - use the email account password from cPanel
- Click Connect - Outlook will test the connection and confirm when done
Outlook 2016
- File > Add Account - select "Manual setup or additional server types," click Next
- Select "POP or IMAP" - click Next
- Fill in the settings:
- Your Name: how you want your name to appear to recipients
- E-mail Address: your full email address
- Account Type: IMAP
- Incoming mail server:
yourserver.ultrawebhosting.com - Outgoing mail server:
yourserver.ultrawebhosting.com - User Name: your full email address
- Password: your email password
- Click "More Settings" - go to the Outgoing Server tab, check "My outgoing server (SMTP) requires authentication," select "Use same settings as my incoming mail server"
- Go to the Advanced tab:
- Incoming server (IMAP): 993, SSL/TLS
- Outgoing server (SMTP): 465, SSL/TLS
- Click OK, then Next - Outlook will test the connection
04. POP3 Setup
POP3 downloads email to your computer and (by default) removes it from the server. Use POP3 only if you specifically want email stored locally and don't need sync across devices.
Follow the same steps as IMAP setup, but:
- Select POP3 instead of IMAP
- Incoming server port: 995 (SSL/TLS)
- Outgoing server settings remain the same (port 465, SSL/TLS)
If you use POP3, enable "Leave a copy of messages on the server" in More Settings > Advanced. This prevents messages from disappearing from Webmail and other devices after Outlook downloads them.
05. Verifying Your Settings
If email was working but stopped, or if you're not sure the settings are correct, verify them:
- File > Account Settings > Account Settings - double-click your email account
- Check the server names - both incoming and outgoing should be
yourserver.ultrawebhosting.com - Click "More Settings" > Outgoing Server tab - "My outgoing server requires authentication" must be checked
- Click "More Settings" > Advanced tab - incoming port should be 993 (IMAP) or 995 (POP3), outgoing should be 465. Both should show SSL/TLS
The username must be your full email address (info@yourdomain.com), not just the part before the @. This is one of the most common setup mistakes we see.
06. Troubleshooting
Outlook Keeps Asking for Password
This is usually caused by Modern Authentication (OAuth2) conflict. Go to File > Account Settings > Account Settings, double-click your account, and make sure the authentication type is set to "Normal Password," not OAuth2. Also clear saved passwords in Windows Credential Manager (Control Panel > Credential Manager > remove entries for your mail server).
Certificate Warning on Connection
If Outlook shows "The name on the security certificate is invalid," change both incoming and outgoing server to your server hostname (webXXX.ultrawebhosting.com) instead of mail.yourdomain.com. The server hostname always has a matching SSL certificate.
Can Send but Can't Receive (or Vice Versa)
Incoming and outgoing use different servers/ports and can fail independently. Check each one against the settings in the featured card at the top of this page.
Error Codes
If Outlook shows a specific error code (0x800CCC0D, 0x800CCC90, etc.), see our Common Outlook Email Errors guide for the fix.

If you only do 5 things from this guide, do these:
- Use manual setup - check "Let me set up my account manually" to avoid OAuth2 issues
- Use your server hostname -
webXXX.ultrawebhosting.comfor both incoming and outgoing - IMAP 993, SMTP 465 - both with SSL/TLS encryption
- Enable SMTP authentication - More Settings > Outgoing Server > check the box
