@Vishnu27 - You're going to need to give us more information than that.

Which email function are you using? How are you defining the attachment?

Here is a simplified example of a formula I use to send a PDF of an HTML Text control on a screen the user is looking at:

Office365Outlook.SendEmailV2( Concat(colSharingList, Mail, ";"), "[PDF] Document", "See attached PDF.<br /><br /><i>This message was sent by 'The Tool'.</i>", { Attachments: Table( { Name: "Document.pdf", ContentBytes: PDF( HtmlText5, { DPI: 72, Margin: "5mm", Size: PaperSize.Letter, Orientation: PaperOrientation.Landscape } ) } ) } )

The colSharingList is a collection of the email addresses I chose on-screen to receive the email. The PDF() function creates the blob object for the Attachments table you pass to the email function.
