title: With Power Query, how to limit Exchange data source to a specific email folder
body: <p>What I am looking for is a way to limit the scope of the query. Getting all the account then navigating to mail and filtering on what I need isn't a issue. The issue is that doing it pulls over 28 000 emails for nothing.</p>
  <p>Here is the beginning of the M code :</p>
  <pre><code>let
      Source = Exchange.Contents(&quot;myMail@myCompany.be&quot;),
      Mail1 = Source{[Name=&quot;Mail&quot;]}[Data],
      #&quot;Other Column deleted&quot; = Table.SelectColumns(Mail1,{&quot;Id&quot;, &quot;Body&quot;, &quot;Categories&quot;, &quot;DateTimeSent&quot;}), 
      ...
  </code></pre>
  <p>Any idea is welcomed.</p>
