Group Conversation Email in Power Query

[Maha1]

Hi,

I'm trying to track our help center mailbox through power query.  How can I identify emails that are in one conversation so I can identify total requests received (distinct count of conversations) and to get duration of first response (Sent date/time of the second email in a conversation MINUS Recieved date/time of the first email in a conversation)?

Hi @Maha1 ,

Please refer to the steps below to get the email.

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("LYo7DsMwDMWu8uAD5AwZ2z1b4EG1FFSoZQX+oOjt4wIZuJDc9/BQ2A+FTKANmxuo8F+JkWYQc5XW7rZOutuS5vbE10dmZP0IuoO1pTHP/hacVZPAD7wqzXrkobwgxHgB", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Text = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"Text", type text}}),
    Custom1 = Table.AddColumn ( 
        #"Changed Type", 
        "New Text", 
        each 
        Text.Combine ( 
            List.Select ( 
                Text.Split ( [Text], " " ), 
                each Text.Contains ( _, "@" ) 
            ), 
            " " 
        ), 
        type text 
    )
in
    Custom1

I don't get the source in your code? I used Get Data from Microsoft Exchange.

What should I replace from your code to make it work?
