Possible to store data in a console Application run as a scheduled tasks?


I have implemented a console application that sends a mail based on the data returned from a web service. I have configured it as a windows task scheduler that runs every 5 mints.

Here I am retrieving a list of employee status using the service. Employee status can be Active, Inactive and few others too. I have to send a notification mail to the employee email id whenever the following status change occurs, "Active-> Inactive" and "Inactive->Active". So in short this requires me to store the previous status.

Is there any way to store the previous data. I tried using static variable. But I believe since the application is run each 5 mints, it starts as a new application. Kindly advice.

I have just a simple main function and SendMail() only.
