Why is the email atachment i sent by BizTalk “body.csv” in OUTLOOK 2016?

Question

I created a simple interface that send an email. I have set the filename by

msg_out_renamed(MIME.FileName) = FileName;

This works fine in my outlook 2013, it shows as "client_inv_20160909090658.csv".

But the receipient who uses Outlook 2016 has it show up as "body.csv". When he decides to save the attachment the filename in the save as dialog is "client_inv_20160909090658.csv".

Why does this happen and is there a way i can prevent this from happening?

Answer 1

Change the context property MIME.FileName for the part of your attachment as well.

In an orchestration: (note the ".part" code)

Message.part(MIME.FileName) = "NewFileName.txt";

In a pipeline component: (note the ".BodyPart" code)

pInMsg.BodyPart.PartProperties.Write("FileName", "http://schemas.microsoft.com/BizTalk/2003/mime-properties", "NewFileName.txt");

Unfortunately we cannot see these context properties via the Message details screen in the BizTalk console. Attach a debugger to inspect these values.
