[KB2872] Resolve issues with sending or receiving emails after installing an ESET home or small office application for Windows

Issue

Solution

1. Pause ESET Firewall in your ESET home or small office application to see if it is affecting the connection between your device and the email server.

2. With ESET firewall paused, check if you can send and receive an email.

3. If the issue persists with ESET firewall paused, uninstall the ESET application and check if you can send and receive an email.

4. If the issue persists after uninstalling the ESET application, verify that:

   • Your device is connected to the internet
   • You can send and receive emails when accessing your account directly through the client website
   • The email client is configured correctly on your device
   • No other firewall is currently installed on your device
     
     

5. When the issue is resolved, reinstall your ESET application.
