Microsoft Project Online is retiring: What you need to know
After more than a decade of supporting project managers and teams around the world, Project Online will officially retire on September 30, 2026. We know this is a significant change, and we want to acknowledge the impact it may have on your organization, your workflows, and your planning processes. This update is exclusive to Project Online and does not affect Project desktop, Project Server, or Planner (which brings together Project for the web, Planner in Microsoft 365, and To Do). Why this change is happening Project Online has served organizations well, but its legacy architecture limits innovation and integration that enhance today’s collaborative work environments, as we announced in 2018. With certain SharePoint Online workflow design tools deprecating in 2026, Microsoft is prioritizing innovation within Planner, Microsoft 365 Copilot, and the Project Manager agent, which represents a new generation of work management tools designed to be more intuitive, scalable, and powered by AI. These tools are built to support both simple task tracking and complex project planning, while integrating deeply across Microsoft 365. What this means for you No immediate disruption: Your current Project Online environment will continue to function as expected until the retirement date. Key dates: October 1, 2025: End of sale for new customers for Project Online-only SKUs. September 30, 2026: Official retirement date – Project Online will no longer be available. Project desktop remains available and is not impacted by this change. Planner remains available and brings together Project for the web (premium plans), Planner in Microsoft 365 (basic plans), and To Do. Transition options There are several transition options available, depending on your organization’s needs: Planner: A unified solution for modern work and project management. Premium features in Planner (included in Planner and Project Plan 3 and Planner and Project Plan 5) deliver portfolios, baselines, dependencies, Gantt charts, and workflow automation via Power App/Accelerator and Power Automate. Premium license holders (including Project Online customers) already have access to Planner and Project desktop. Now in public preview, Planner introduces Project Manager agent for Microsoft 365 Copilot users—an AI assistant that automates task creation, status reporting, and execution, adapting to your project’s context and generating professional reports across Planner views. Project Server Subscription Edition: Designed for organizations needing advanced project and portfolio management (PPM) or a close match to the feature set of Project Online. Project Server Subscription Edition provides comprehensive planning, scheduling, and resource management tools, built on the latest SharePoint Server technology. Dynamics 365 Project Operations: Tailored for customers who require robust timesheet management and resource scheduling, Dynamics 365 Project Operations offers integrated tools for project delivery and financials. How to prepare This retirement will happen automatically on the specified dates with no admin action required. You may want to notify your users and update any internal documentation to reflect the above changes. Evaluate the alternatives proposed above and plan the transition immediately. Back up your data, if needed, before the retirement date. Looking ahead We fully understand the challenge associated with this or any product retirement. We remain excited about the future of our Work Management solutions with enhancements coming to Planner, including advancements in AI-powered project management. With Planner and our AI-powered roadmap, we’re building a future where project management is intuitive, collaborative, and deeply integrated into the flow of work across Microsoft 365. Planner and the Project Manager agent are just the beginning of a more intelligent, integrated, and collaborative project management experience.

I created Project Online workflow using SharePoint Designer 2013 and published it. The workflow contains no errors as validated on SP Designer 2013. I create a project using the EPT that is linked to the published workflow, and updated all the mandatory fields.

Timesheet or time tracking functionalities in Project for the Web/Planner Premium
Hi, I've been looking for information about whether timesheet or time tracking capabilities will be made available in a not so distant future in PFTW of Planner Premium. I work at a company where we already have an instance of Project Online running in which timesheets are managed. We would like to have some sort of time tracking in PFTW/Planner premium as well since we're launching a project on that platform soon. Does anyone have a view on what's coming or any experience on how to do time tracking in PFTW/Planner Premium? Thanks! N.
Project Web App can't delete PDP despite custom scripting being enabled
Hi everyone, Currently trying to set up a Project Web App system and I've encountered this problem. When trying to delete/remove a project detail page from a project nothing happens. My organisation has custom scripting enabled and I can remove fields and other stuff from projects but when I try to remove a page it doesn't work. I've removed all fields from the page I'm trying to delete so I don't think its anything to do with a required field or existing workflow, and I get no error message when I try to delete the page. I simply click "Delete Page", stop editing and the page is still there with no change. Anyone have any ideas on what could be causing the issue?
How to Submit a Timesheet on Behalf of Another User in Project Online using API?
I develop a flow that once a week submit timesheets for all users. Is there a way to submit a timesheet on behalf of another user? I have tried the endpoint: _api/ProjectServer/TimeSheetPeriods('periodid')/TimeSheet However, it works only in the current user's context. When I run a Power Automate flow as an Admin, the flow can only see the Admin's timesheets. Could you please advise how I can submit a timesheet for another user?
Project Online (CSOM): Encountering 'User Not Found in Active Directory or Project DB'
Issue We are attempting to access Project Online data in Project Permission mode using app-only authentication, specifically to bypass MFA for programmatic access, as we aim for continuous, automated access without any user-interaction. We are using CSOM, using Microsoft.ProjectServer.Client.ProjectContext in .NET 4.8 to connect to Project Online. Despite following several documented approaches with client certificates, client secrets, and OAuth configurations, we keep encountering errors like 401 Unauthorized and User not found in Active Directory or in project db. Below is a summary of our steps. Despite multiple attempts, we consistently receive errors blocking access. We have followed recommended documentation for client credentials, certificates, and permissions but still face access issues. Technology Project Online CSOM in .NET 4.8 Microsoft.ProjectServer.Client.ProjectContext Azure AD (Entra ID) Solutions Attempted Client Certificate Authentication: Configuration: Registered an app in Azure AD (Entra) with a client certificate and set permissions including Sites.FullControl.All. NOTE: we could not select Project permissions (Project.Read, etc.) in the Application Permissions screen, only within the delegated permissions screen. Token Acquisition: We acquired an access token using az account get-access-token --resource=https://.sharepoint.com. Request Attempted: URL: https://%3Ctenant%3E.sharepoint.com/sites/%3cproject-site%3e/_api/ProjectData/Projects Outcome: {"error":"invalid_request","error_description":"App is not allowed to call SPO with user_impersonation scope"} Client Secret with Client Credentials: App Registration: Configured client ID and client secret in Azure AD with permissions for Project.ReadWrite.All and Sites.Selected. Token Acquisition: Called the token endpoint: Endpoint: https://login.microsoftonline.com/%7bTENANT_ID%7d/oauth2/v2.0/token Parameters: client_id, scope= https://%3Ctenant%3E.sharepoint.com/.default, client_secret, grant_type=client_credentials Access Attempt: URL: https://%3Ctenant%3E.sharepoint.com/sites/%3cproject-site%3e/_api/ProjectData/Projects Response: HTTP/1.1 401 Unauthorized Response Body: " " Outcome: Despite obtaining a valid token, the request returns a “Please sign in” page, rather than an access token. SharePoint AppPermissionRequest Configuration using /sites/pwa/layouts/15/appinv.aspx: Configuration: Set up AppPermissionRequest XML in SharePoint for permissions like: Outcome: This configuration did not make any differences, and did not grant the required permissions in Project Permission mode, as SharePoint app permissions do not seem to cover Project-specific access, it seems. Project Online access remains blocked. <AppPermissionRequest Scope="[http://sharepoint/content/sitecollection]" Right="FullControl"/> Microsoft Graph API Exploration: Goal: Investigated Graph API as an alternative. Outcome: Microsoft Graph lacks Project Online-specific permissions, limiting access to SharePoint and directory data, which does not meet our need for project-specific data access. Microsoft.Identity.Client and client certificate Configuration: CSOM using the following code to login: Outcome: Access fails with User:<customercontent></customercontent> not found in Active Directory or in project db public static void Login(this ProjectContext context) { var clientId = "xxx"; var clientSecret = "xxx"; var authority = "https://login.microsoftonline.com/xxx"; var scope = "https://xxx.sharepoint.com/.default"; var certificate = new X509Certificate2("c:\\temp\\cert.pfx", "xx"); var app = ConfidentialClientApplicationBuilder.Create(clientId) .WithCertificate(certificate) .WithAuthority(new Uri(authority)) .Build(); AuthenticationResult result = TaskHelper.BlockingAwait(() => app.AcquireTokenForClient(new[] { scope }).ExecuteAsync()); string accessToken = result.AccessToken; context.ExecutingWebRequest += (sender, e) => { e.WebRequestExecutor.RequestHeaders["Authorization"] = "Bearer " + accessToken; }; } Key Questions: Is there a method for app-only authentication in Project Online in Project Permission mode__ that bypasses MFA for automated access? Has anyone succeeded in applying app-only credentials for Project Online access__, specifically in Project Permission mode? Are there any alternative permission configurations__ (like Azure AD settings, conditional access policies, or app permissions) that could facilitate this access? Thank you in advance!
