How to preconfigure SSO domains for the Office 365 add-in for the Zoom app

Zoom Outlook admins can integrate the Zoom Outlook add-in with the single sign-on (SSO) URL pre-configured in the add-in, greatly simplifying deployment. After the URL for the add-in is preconfigured, users are automatically prompted to use SSO to authenticate with the system when interacting with the add-in, e.g. B. by clicking the Add Zoom Meeting button or the Settings button within the add-in.


  • If you use custom manifest files, the add-in will not receive automatic updates and you must manually update it with a new manifest file to receive updates.
  • It is important to note that if the add-in has a pre-configured SSO URL, it cannot automatically log into the add-in upon deployment.

Prerequisites for managing SSO domains for the Outlook add-in

  • Your Zoom account has been configured with single sign-on (SSO).
  • The owner of the account or the administrator of the account

  2. Open the manifest file with a text editor and start editing.
  3. Replace the current value in %value% by c7740fe1-f1ea-4869-9bec-fc827930b38f.
    For example, if your manifest file lists the ID as a7ca6c74-33fb-43a4-a3e4-781078f0eff5change the line to c7740fe1-f1ea-4869-9bec-fc827930b38f.
  4. Two lines appear in the manifest that you need to find:
    <bt:Url id="messageReadTaskPaneUrl" DefaultValue=""/>
    <bt:Url id="functionFile" DefaultValue=""/>
    <bt:Url id="phoneTaskpaneReadUrl" DefaultValue=""/>
  5. Replace these lines with the lines above with the following lines respectively:
    <bt:Url id="messageReadTaskPaneUrl" DefaultValue=";domain=%ssodomain%"/>
    <bt:Url id="functionFile" DefaultValue=";domain=%ssodomain%"/>
    <bt:Url id="phoneTaskpaneReadUrl" DefaultValue=";domain=%ssodomain%"/>
  6. By replacing “%ssodomain%” with the name of your domain, you can change the newly added lines. Using as an example, you can simply replace “mycompany” instead of “%ssodomain%”.
