title: FileHandler is visible in Teams Application's "files" tab
body: <p>We have a customized file opening solution that uses FileHandler integration for opening files from onedrive and sharepoints document library. Recently we have observed that FileHandler was visible in Teams Application's(Web view and Desktop app) &quot;Files&quot; tab also. This behaviour is inconsistent as it is only visible for some users in our tenants.</p>
  <p>This behaviour only observed on Microsoft Teams Version 1.5.00.5967 (64-bit).</p>
  <p><strong>Expected or Desired Behavior</strong></p>
  <p>According to documentation <a href="https://docs.microsoft.com/en-us/onedrive/developer/file-handlers/?view=odsp-graph-online" rel="nofollow noreferrer">here</a> of FileHandler, it should only be visible on sharepoint and onedrive. Is this an upcoming feature for Teams as well?</p>
  <p><strong>Observed Behavior</strong></p>
  <p>File handler is visible on Teams Files tab for some users in our tenant.</p>
