• Microsoft Outlook should be setup as the default email client on Windows in order for Informatica PowerCenter Email task to send emails. This can be setup from Start > Control Panel > Internet Options > Programs. Ensure that Microsoft Office Outlook is selected as the default email program on the Informatica PowerCenter Server as shown below.

• Verify that the Informatica PowerCenter service is running without any issues and both the Repository and Integration services are up.

• Port 25 is the default port used to transport or communicate email across the Internet using the SMTP protocol. Ensure that this port is not blocked or used by any other process on the Informatica PowerCenter Server. To check, if a port is in use on a Windows based system, the below command can be run in the command prompt.

netstat -ano -a: Displays all active connections and the TCP and UDP ports on which the computer is listening. -n: Displays active TCP connections, however, addresses and port numbers are expressed numerically and no attempt is made to determine names. -o: Displays active TCP connections and includes the process ID (PID) for each connection. If the hMailServer is already installed, the port 25 would be in use as shown below.

The process that is using Port 25 is having a PID: 1200. The process can be found out in the Windows Task Manager as shown below.
