Pre-configure SSO login domains for Office 365 add-in Follow


With the Zoom Office 365 add-in, administrators can deploy the add-in, with the single sign-on (SSO) url preconfigured. With the url preconfigured, if a user is using the Add a Zoom Meeting or Settings options in the add-in, it will automatically use SSO to authenticate. 

Note: When using custom manifest files, the Add-in will not receive automatic updates, and must be updated with a new manifest file. 

This article goes over:


  • SSO configured for your Zoom account

Configuring the manifest file

  1. Download the manifest file for the Outlook Add-in
  2. Open the manifest file in a text editor.
  3. Replace the current value in <Id>%value%</Id> with c7740fe1-f1ea-4869-9bec-fc827930b38f.
    For example if your manifest file lists the ID  as <Id>a7ca6c74-33fb-43a4-a3e4-781078f0eff5</Id>, change the line to <Id>c7740fe1-f1ea-4869-9bec-fc827930b38f</Id>.
  4. Find the following lines in the Manifest (they will appear two times):
    <bt:Url DefaultValue="" id="messageReadTaskPaneUrl"/
    <bt:Url DefaultValue="" id="functionFile"/>

    <bt:Url DefaultValue=";domain=%ssodomain%" id="messageReadTaskPaneUrl"/>
    <bt:Url DefaultValue=";domain=%ssodomain%" id="functionFile"/>
