Hi Sinduja,
To address your follow-up question, there's not a native function in Blue Prism that can ping an Exchange server (like an Action in a VBO, for example), but it may be possible to create an Object that could automate using the 'ping' command from a command prompt to do this. Although the Command Prompt 'cmd.exe' cannot be directly launched by Blue Prism's Application Modeler, you can follow the guidance in
this Knowledge Base article to use the out-of-the-box 'Utility - Environment' VBO and place the commands to be run in a batch file, then place the full path and filename of the batch file into the 'Application' input parameter field.
However, I would second my colleague Luis' suggestion to use an external tool which can check the status of a server, then create your own VBO for this tool to automate validation of the results, then incorporate this into your Process to run at an interval and take action accordingly depending on the result.
