Inspire Planner provides you with the ability to share projects with external contacts by adding them as a project collaborator.
When a project is shared with an external contact, the contact receives an email with a link that takes them to the Inspire Planner external project portal where they can see the project and update their assigned Salesforce tasks.
This help article shows you how to enable the Inspire Planner external project portal for your Salesforce org.
Please note the following:
To enable the Inspire Planner external project portal, go to the App Launcher and enter "Inspire Planner Settings" in the Quick Find box. Then click on Inspire Planner Settings.
Look for the setting called "Enable sharing of projects to external contacts" and toggle to "Enabled".
A dialogue window will display onscreen. Allow access by clicking on Allow.
You will receive a confirmation message onscreen.
