Pre-configuring the Outlook add-in

Last Updated:

With the Zoom Outlook add-in, administrators can deploy the add-in with the single sign-on (SSO) URL preconfigured. With the URL preconfigured, users will automatically use SSO to authenticate when they interact with the add-in, such as click the Add a Zoom Meeting or Settings options in the add-in.


  • When using custom manifest files, the add-in will not receive automatic updates, and must be updated with a new manifest file. 
  • If the add-in is deployed with a preconfigured SSO URL, this will prevent automatic logins for the add-in

This article covers:

Prerequisites for managing SSO domains for the Outlook add-in

  • SSO configured for your Zoom account
  • Account owner or admin access

How to configure 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 id="messageReadTaskPaneUrl" DefaultValue=""/>
    <bt:Url id="functionFile" DefaultValue=""/>
    <bt:Url id="phoneTaskpaneReadUrl" DefaultValue=""/>
  5. Replace those lines with 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. Modify the newly added lines by replacing "%ssodomain%" with your domain. For example, if your Vanity URL is, replace "%ssodomain%" with "mycompany".
  7. Save the file.
