title: Retrieving Public Folders via Microsoft Graph API
body: <p>I have an application that uses the Microsoft Graph API to read and write emails from a mailbox.</p>
  <p>I'm making a request to URL</p>
  <p><code>GET https://graph.microsoft.com/v1.0/users/{user_id}/mailFolders/PublicFoldersRoot/childFolders</code></p>
  <p>This used to work, but since April 2021 it broke and now returns an error</p>
  <pre><code>{
      &quot;error&quot;: {
          &quot;code&quot;: &quot;ErrorMailboxMoveInProgress&quot;,
          &quot;message&quot;: &quot;Mailbox move in progress. Try again later., Cross Server access is not allowed for mailbox UUID&quot;
      }
  }
  </code></pre>
  <p>No mailboxes have been initiated to move in my account.</p>
  <p>I found the same thread on this issue, but there is no solution yet. <a href="https://docs.microsoft.com/en-us/answers/questions/403433/mailbox-move-in-progress-try-again-later-the-user.html" rel="nofollow noreferrer">Mailbox move in progress</a>.</p>
  <p>I didn't find out any workaround. Please help if you know how to fix this.</p>
