We are using Win XP as our operating system & MS outlook 2003 as a mail client. Our User has received a mail from one of our customer & he gets the above error. He forwarded that mail to me to rectify the problem. Tried most of the options searched on the net in outlook 2003.

1. Allowing ActiveX controls from the restricted zone.
2. Replacing Restricted zone option to Internet Zone.
3. Changing the options "Use Microsoft Office Word 2003 to edit e-mail
messages" & "Use Microsoft Office Word 2003 to read Rich Text e-mail
messages"
4. Changing the message format: 1. HTML, 2. Rich Text, 3. Plain Text.

Applying the above options still teh problem is not resolved. PLs help me to sort this issue as the customer is important for us & we receive n mails from him.

Thanks a lot in Advance for your kind support.
