How to Fix "Authentication Failed" Error

Getting an "Authentication Failed" error when trying to access your email? Let's fix it!

Quick Fix #1: Check Your Password

This fixes most cases!

Try These Steps:

1. Retype your password carefully
   • Check for typos
   • Make sure Caps Lock is OFF
   • Watch for extra spaces
2. Copy and paste your password (if you have it saved)
3. Try typing it in a text editor first to see what you're typing

Quick Fix #2: Verify Your Username

Your username must be your FULL email address:

Correct Format:

• ✅ you@yourdomain.com
• ✅ john.smith@company.com

Wrong Format:

• ❌ you (missing domain)
• ❌ you@yourdomain (missing .com)
• ❌ yourdomain.com (missing username)

Quick Fix #3: Reset Your Password

If you're not sure about your password:

1. Go to system.atriomail.com
2. Navigate to Email Mailboxes
3. Click on your email address
4. Click "Reset Password"
5. Enter a new strong password
6. Update the password in your email app

Fix #4: Check Server Settings

Wrong server settings can cause authentication errors:

Fix #5: Enable SMTP Authentication

Your outgoing server MUST have authentication enabled:

1. Open your email app settings
2. Go to outgoing (SMTP) server settings
3. Check "My outgoing server requires authentication"
4. Use same username and password as incoming

Fix #6: Remove and Re-add Account

Sometimes starting fresh helps:

1. Remove your email account from the app
2. Restart your device
3. Add the account again with correct settings
4. Use your FULL email address as username
5. Enter password carefully

Fix #7: Check Account Status

Make sure your account is active:

1. Log into system.atriomail.com
2. Go to Email Mailboxes
3. Check if your mailbox shows as "Active"
4. If suspended, contact support

Fix #8: Try Webmail

Test if you can log in via webmail:

1. Go to your webmail at https://system.atriomail.com/webmail
2. Try logging in with same credentials
3. If webmail works, the issue is with your email app settings
4. If webmail fails too, reset your password
