Outlook 2007 loose file extension in Vista

Hi friends,

I am facing an issue with Outlook 2007,whenever i try to right-clicking on any file which is being attach in an email and i try to select as Save As.It's getting stored but it's showing me a wrong extension.for example i am having a file which is being attach as .doc but after selecting Save As option.It's showing me as .pdf. I don't know whats wrong but is i try to open same email on some else machine it's showing me proper extension.

Can anyone help me out with this issue.

Sure i will help you out with this it might happen that there would be some issue .But there is one more way of opening a file by right clicking on any File and over here select open with and now select the file in which application you want to Open and if the application is not being mention then select Choose the program option and also have check mark which says Always use the program to open such kind of file.
