Before You Start
Make sure you have:
- Microsoft Outlook installed
- Your full email address (you@yourdomain.com)
- Your email password
- Internet connection
Method 1: Manual Setup (Recommended)
Entering the settings yourself is the most reliable way to connect Outlook.
Step 1: Start Manual Setup
- Launch Microsoft Outlook
- If this is your first account, you'll see the welcome screen; if not, go to File → Add Account
- Enter your email address
- Click "Advanced options"
- Check "Let me set up my account manually"
- Click "Connect"
Step 2: Choose Account Type
- Select "IMAP" (recommended)
- Click "Connect"
Step 3: Incoming Mail Settings
Enter these settings exactly:
- Server: mail.atriomail.com
- Port: 993
- Encryption: SSL/TLS
- Username: Your full email address
- Password: Your email password
Step 4: Outgoing Mail Settings
Enter these settings:
- Server: mail.atriomail.com

Step 5: Complete Setup
- Click "Next"
- Wait for Outlook to test the connection

Method 2: Let Outlook Look Up the Settings
Outlook can try to find the settings on its own. This does not work for every domain, so check the result:
- Go to File → Add Account
- Enter your email address and click "Connect"
- Select "IMAP/POP" if prompted, then enter your password
- If Outlook fills in settings, make sure both servers are mail.atriomail.com with the ports above
- If it fails, or shows a different server, use Method 1
Test Your Email
- Send a test email to yourself
- Check if you receive it
- Try replying to the test email
- Verify sent items appear in Sent folder
