Outlook is unable to connect to the mail server. This is usually due to:

  • No internet connection
  • Incorrect Outlook configuration
  • Blocked ports by firewall/antivirus
  • Corrupt Outlook profile or PST/OST file

Troubleshooting Steps:

  1. Check Internet Connection – Make sure the system is online.
  2. Verify Mail Server Settings – Go to  File > Account Settings > Server Settings     
  1. Ensure the incoming/outgoing server names, ports, and encryption type are correct as below
    1. Incoming and outgoing server name: gnal.mithiskyconnect.com
    2. Incoming Port: IMAP 993SSL POP995SSL
    3. Outgoing port: 587 STARTLS or 465 SSL/TLS
  2. Disable Firewall/Antivirus Temporarily – These might be blocking Outlook from reaching the server.
  3. Test via Webmail – If webmail works, it indicates the issue is with Outlook configuration or the local device.
  4. Start Outlook in Safe Mode
    1. outlook.exe /safe -  This helps to check if an add-in is causing issues.
  5. Repair Outlook Profile – Go to Control Panel > Mail > Profiles and repair the current profile.
