Send Outlook Mail Message - Excpetion: Could not connect to Outlook

We are using RDS windows server that allows multiple users to login and run different processes. I have 2 process with 2 different user login that runs at the same time and some times finishes at the same time. When process 1 send email for successful process run the same time process 2 fails to send email for successful process run and throw an error like this:

Send Outlook Mail Message - Excpetion: Could not connect to Outlook. Please try to run both programs as Administrator ( or not as Administrator). If the error persists this might be due an corrupt Office installation. Please repair Office installation.
