[Power Query] Receiving The email address from Microsoft Exchange source via Power Query.

Aim: Receiving The email address dynamically from Microsoft Exchange source via Power Query.

I want the source name to be returned as a new column.

I have tried many things but i failed


Below is my code:

let
    Source = Exchange.Contents("xxx yyy.zzz"),
    MailTable = Source{[Name="Mail"]}[Data]
in
    MailTable

Any one have some ideas?

P.S. I can not add "At sign" in my post!
