Emailing back a file

[ddpadil (Dilip)]

Didn’t get your requirement completely but what i understand is rather than sending each file to multiple recipient you wanna send multiple attachment to multiple recipient at single shot.
How about zip the attachment and send the mail to multiple recipient.

Attach all files in a folder

You can try this. You need to open your .XAML file in notepad, search for AssemblyReference where you will see all the Namespaces imported to your workflow. At the end add a Tag Even your code should work after you add the reference. <AssemblyReference>System.IO.Compression.FileSystem</AssemblyReference>
