We have our shop floor computers set up with our ERP system access. They
excecute a workflow process in the system which requires emailing through
outlook. For this to work, outlook should be opened.

SHop floor people, by mistake, close outlook and this causes a lot of problems

Is it possible when one restarts the computer or anytime when the computer
is on, even if someone accidently closed outlook, it still keeps running?

We tried a software called 4T Tray MInimizer Program which works great with
accidently closing the outlook. It keeps it running.
But with this software, if someone restarts the computer, the outlook is not
lauched through 4T and so when someone accidently closes outlook this doesn't
work.

Any help would be greatly appreciated. Thanks in advance.
