Thank you for your patience.&nbsp;<\/p>\n<p><b>[Introduction:]<\/b>  <\/p>\n<p>We\u2019re introducing a simplified external collaboration (EC) admin experience in  <i>Microsoft Teams<\/i> to help administrators manage external collaboration settings more efficiently. This update introduces two predefined collaboration modes\u2015Open and Controlled\u2015as well as a Custom mode for organizations with unique requirements. The new   experience provides a streamlined interface in the <i>Teams admin center (TAC)<\/i> for configuring external collaboration policies across chats, calls, meetings, Teams, and channels (including shared channels).<\/p>\n<p><b>[When this will happen:]<\/b>  <\/p>\n<p><b>Public Preview:<\/b> Rolling out mid-November 2025; expected completion by mid-November 2025.  <\/p>\n<p><b>General
