I needed to download the Microsoft Project Professional desktop application/client or the Project Online Desktop client, so I created a trial subscription for the Microsoft Planner and Project Plan 3. I received the email below.

“Your new Planner and Project Plan 3 - Trial subscription is now available. To set it up, sign in to the Microsoft 365 admin centre with the email address that you created when you signed up for the subscription. Save your sign-in email and bookmark the website address for the admin centre: [admin.microsoft.com] To set up your subscription, complete these steps in the admin centre:

  • Connect your organisation’s domain. This will update your sign-in email.
  • Invite your team to use Planner and Project Plan 3 - Trial.
  • Manage payment and billing detail”

 

There was a link for me to set up my subscription. When I clicked the link, it took me to my account but I don’t know how to connect my organisation’s domain to update my sign-in email, so I need help to do this.

Also, when I signed in, the “subscription” tab did not

    To connect your organization’s domain and update your sign-in email in Microsoft 365, follow these steps:

    1. Sign in to the Microsoft 365 admin center using the email address you created when signing up for the subscription.
    2. In the admin center, navigate to the Manage domains page. This is where you can add your custom domain.
    3. Follow the prompts to add your domain. You will need to verify ownership of the domain by following the instructions provided, which typically involve updating DNS records at your domain registrar.
    4. Once your domain is verified, you can set up email addresses that use your custom domain instead of the default onmicrosoft.com address.
    5. After connecting your domain, you can invite your team to use Planner and Project Plan 3 as instructed in the email you received.

    If you need further assistance, you can refer to the Microsoft documentation on adding a domain to Microsoft 365 for more detailed steps.

    Hi @Joseph Nnodim,

    Thank you for posting your question in the Microsoft Q&A forum.

    To set up the free Microsoft Planner and Project Plan 3 subscription, you can follow these steps:

    1/ Register for a free subscription

    • Sign up for a free Planner and Project Plan 3 subscription and follow the prompt to proceed (which you have already done).
    • During sign‑up, Microsoft creates your tenant (e.g., yourtenant.onmicrosoft.com) and an initial admin user (e.g., ******@yourtenant.onmicrosoft.com). You will need to save these credentials since this is what you’ll use for admin.microsoft.com.

    2/ Sign in to the Microsoft 365 Admin Center

    • Go to admin.microsoft.com and sign in with your work/school admin (the …@onmicrosoft.com account above).
    • If you're prompt to set up your organization domain, you can follow the guidance in these articles:

    (+) Add a domain to Microsoft 365 - Microsoft 365 admin | Microsoft Learn

    (+) Add DNS records to connect your domain - Microsoft 365 admin | Microsoft Learn

    3/ Assign the Plan 3 license for your account

    • In the admin center, go to Users > Active users > choose the user (yourself) → Licenses & apps, ensure Planner and Project Plan 3 is assigned. If not, toggle it on and save.
    • After assigning a license successfully, you can download and use Project desktop and Planner web app now.

    Hope this information will be helpful. If you have any questions or need additional help, please feel free to ask them in the comments so that I can continue to support you.

    Thank you for your understanding and corporation. Looking forward to your response.
