Get email attachment with receivedtime

[Comprateur]

Hello, 

I'm learning Dataflow and Queries and I'm trying to load into a Lake an email with an excel attachment with the email received date. 

I cannot find the way to add the email received date as a column of the excel. 

Thanks for your help.

Thanks, 

I think I understand what you are saying ", doesn't have to be the exact previous step. You would need to use the advanced editor though as this cannot be done in the UI " But I don't know how to extract that information at the a particular step and reuse it late. 

Again thanks for your help.

Here is an example where the email receive timestamp is blended into the table from the Excel attachment

let
    Source = Exchange.Contents(<email address>),
    Mail1 = Source{[Name="Mail"]}[Data],
    #"Filtered Rows" = Table.SelectRows(Mail1, each ([HasAttachments] = true)),
    #"Filtered Rows1" = Table.SelectRows(#"Filtered Rows", each Date.IsInPreviousNDays([DateTimeReceived], 1)),
    #"Expanded Sender" = Table.ExpandRecordColumn(#"Filtered Rows1", "Sender", {"Name", "Address"}, {"Name", "Address"}),
    #"Filtered Rows2" = Table.SelectRows(#"Expanded Sender", each ([Name] = <Sender>)),
    #"Removed Other Columns" = Table.SelectColumns(#"Filtered Rows2",{"DateTimeReceived", "Attachments"}),
    #"Expanded Attachments" = Table.ExpandTableColumn(#"Removed Other Columns", "Attachments", {"Name", "Extension", "IsInline", "Size", "ContentType", "Last Modified", "AttachmentContent"}, {"Name", "Extension", "IsInline", "Size", "ContentType", "Last Modified", "AttachmentContent"}),
    #"Filtered Rows3" = Table.SelectRows(#"Expanded Attachments", each ([Extension] = ".xlsx")),
    AttachmentContent = #"Filtered Rows3"{0}[AttachmentContent],
    #"Imported Excel Workbook" = Excel.Workbook(AttachmentContent),
    Detail_Sheet = #"Imported Excel Workbook"{[Item="Detail",Kind="Sheet"]}[Data],
    #"Promoted Headers" = #table({"Received"},{{#"Filtered Rows3"{0}[DateTimeReceived]}}) & Table.PromoteHeaders(Detail_Sheet, [PromoteAllScalars=true])
in
    #"Promoted Headers"

Note the last line before "in"

#"Promoted Headers" = #table({"Received"},{{#"Filtered Rows3"{0}[DateTimeReceived]}}) & Table.PromoteHeaders(Detail_Sheet, [PromoteAllScalars=true])

Where you can see that a previous step #"Filtered Rows3"  is referenced.

Hi, 

I was going to the work direction trying to use parameters or references. 

It kind of works, but I have 2 additional questions.

How can I retrieve all sheets in a workbook using 

Detail_Sheet = #"Imported Excel Workbook"{[Item="Detail",Kind="Sheet"]}[Data],

And second question, how can you get all line from the excel filled with the Received time? In order to always know the datetime received when I analyse my Excel data at later stage.

thanks,

1. You would add steps to enumerate all sheets, and concatenate them if they have the same structure

2. Instead of adding the value as a row, add it as a column.

Thanks, 

not sure that what you ment but I have been able by adding a new column to the table extracted from excel. 

Table.AddColumn(Table.PromoteHeaders(#"Filtered rows 3", [PromoteAllScalars = true]) ,"Received", each #"Expanded Attachments"{0}[DateTimeReceived], type date)

 For having all sheets yes they are in the same format and I have expanded Data from the Excel and it works. 

Thanks a lot for your help and patience.

Hi, How can you save the email meta data for having it use later during the transform, Is it possible to record it into a variable and call it at a later stage?

Power Query steps can reference any prior steps, doesn't have to be the exact previous step. You would need to use the advanced editor though as this cannot be done in the UI

The Email Received date is part of the Email meta data, not the Excel meta data. You need to grab that independently, before you interpret the Excel data.
