Hi,

Currently I have an application that reading mails from exchange server with help of outlook DLL and redemption DLL (third party). According to company security policy this is not correct. So we are going to move mail box on company's local mail server and trying to read mail without third party DLL. we can not use outlook DLL because we are going to deploy this application on production server and there is a policy to not install office on server. Could you suggest how can I do this ?

We don't have to use any third party DLL.

Your suggestion and help are welcome

Thanks in advance.
