How to Connect Mailbux to Microsoft Outlook

Connect Mailbux to Microsoft Outlook

You can add your Mailbux email account to Microsoft Outlook on Windows, Mac, or the web. This guide covers the manual IMAP/SMTP setup that works with all versions of Outlook.

What You Need Before Starting

• Your full Mailbux email address (e.g. john@yourdomain.com)
• Your Mailbux account password

Server Settings

Setting	Incoming (IMAP)	Outgoing (SMTP)
Server	my.mailbux.com	my.mailbux.com
Port	993	587
Encryption	SSL/TLS	STARTTLS
Username	Full email address	Full email address
Password	Your password	Your password

Setup in Outlook (Windows / Mac)

1. Open Outlook and go to File > Add Account.
2. Enter your full email address and click Connect.
3. If Outlook tries to auto-configure and fails, choose IMAP from the account type options.
4. Enter the incoming mail settings:
   • Server: my.mailbux.com
   • Port: 993
   • Encryption: SSL/TLS
5. Enter the outgoing mail settings:
   • Server: my.mailbux.com
   • Port: 587
   • Encryption: STARTTLS
6. Enter your password and click Connect.
7. Outlook will verify the settings and add your account.

Setup in Outlook on the Web (Office 365)

1. Go to Settings > View all Outlook settings > Mail > Sync email.
2. Click Other email accounts.
3. Enter your name, email address, and password.
4. If prompted for manual settings, use the server details from the table above.

Troubleshooting

• Authentication failed: Double-check your username is the full email address, not just the local part.
• Cannot connect to server: Make sure you are using port 993 for IMAP and port 587 for SMTP. Do not use port 465.
• Emails not sending: Confirm SMTP authentication is enabled and you are using STARTTLS on port 587.

Verify Your Setup

If you are having delivery issues after connecting, check these:

• SMTP Test — confirm your outgoing server is reachable
• MX Lookup — verify your domain MX record is correct
• Blacklist Check — check if your IP is on any spam lists
