1. Introduction
When WorkPoint Express 365 is released for production use, WorkPoint intends to make the Add-In available for download directly from the Microsoft Office Store. In the meantime, for testing and preview purposes, the application must be deployed by uploading an application manifest file to your Outlook profile.
In this article, we present two options for deploying WorkPoint Express 365 so you can start using the Add-In with your own Outlook profile and WorkPoint solution.
Before selecting a deployment strategy, please take a moment to review the following caveats regarding the preview release:
WPE365 Preview is only available for V4 Solutions in the Release Candidate (RC) ring.
Please visit this article for Express365 manifest downloads, which is needed for deploying Express365.
To use the Add-in, ensure your WorkPoint solution is in the RC ring. You can verify this by checking the footer section of the WorkPoint My Tools menu in the SharePoint Web UI, as shown in the image below.

If the platform does not display NewPlatformRC, please contact your Partner Enablement representative to discuss changing the platform ring or setting up a new solution for the preview.
New Outlook Only
At present, the WorkPoint Express 365 Add-In is only supported in the New Outlook application. Eventually, WorkPoint Express 365 will be available across the M365 Productivity Suite. For the time being, however, our focus is on supporting e-mail Workflows using the New Outlook Application.

Primary Mailbox User and WorkPoint Solution must be in the same Microsoft Azure Tenant
WorkPoint Express 365 uses the profile of the "Primary Account" in Outlook to automatically authenticate with the SharePoint and WorkPoint services.
This means that, at present, WorkPoint Express 365 can only access and navigate WorkPoint solutions in the same Tenant as your Primary Account in your Outlook profile.
If you wish to use WorkPoint Express 365 native Outlook (New) Application and your desktop profile and WorkPoint solution are in different Azure tenants, you will need to add the mailbox account of your WorkPoint user as the "Primary Mailbox" in your Outlook profile. More information about nominating a primary account in Outlook can be found here.
For example: In the screenshots below, my main Outlook Email Account is in the workpoint.dk tenant, while the WorkPoint solution I wish to access with WorkPoint Express 365 in the workpointdemo tenant.
To use WorkPoint Express 365 in my Outlook application I must nominate the workpointdemo user as the primary account. One way to achieve this is by setting the workpointdemo account as the "Primary Account" in the Outlook Settings panel per the screenshots below.
Alternatively, for testing/preview purposes, you might find it easier to simply access Outlook in the Web Browser (https://outlook.office.com) and authenticate directly as the testing user in the same tenant as your WorkPoint solution.
2. Deployment options for WorkPoint Express 365
For testing purposes, two options are available for deployment.
These options are described in separate articles which will guide you through the process of enabling the add-in in your own environment. Once deployed, you can then proceed to the Getting Started with WorkPoint Express 365 article to start using WorkPoint Express 365 with your own Outlook profile and WorkPoint solution.
The two deployment options are:
Deployment via Microsoft Admin Portal: useful for deploying WorkPoint Express Add-In to multiple users, however, this approach requires either Global Administrator or Exchange Administrator roles in your tenant, and once access and is subject to a ~6hr propagation delay before it becomes available in your users' Outlook profiles. You can read more about this deployment option in this article.
Deployment via Side Loading into Outlook: useful for single user, quick tests in a test environment. Provided your administrator has not disabled loading Custom Add-Ins, the WorkPoint Express 365 add-in manifest can be added to your Outlook profile. You can read more about this deployment option in this article.
