Thank u Peter for prompt answer,
I have not any knowlege about PHP. basically I am dot net develper.
Your application is so good that I installed it on my website. through your installation guide (which was so easy like A,B,C...)
You told to enable IMAP extention in PHP.
Do this in osTicket applications' PHP file or somewhere in website-hosting control panel. My website hosting provider give me Helm contrl panel with limited access.
Please guide me to solve this problem.
Thanks
