Firstly you need to contact the support people for "rediff" whatever that
is.
secondly, This newsgroup is for support of Outlook
97/98/2000/2002/2003/2007 from the Office suite of products.  Outlook
Express is actually a separate program despite the similar name.

For help with your OE questions, try an OE newsgroup such as
microsoft.public.windows.inetexplorer.ie6_outlookexpress (for OE 6), or
an OE help website such as http://insideOE.tomsterdam.com.  If you're
accessing the Microsoft newsgroups through the MS Product Support
Services "Community Newsgroups" web interface, click
http://www.microsoft.com/communities/newsgroups/list/en-us/default.aspx?dg=micro
soft.public.outlookexpress.general
Good luck!
