Microsoft is rolling out a major update to Microsoft Planner in early 2026 that both adds new capabilities and removes several longstanding features — most notably the ability to publish Planner tasks as an iCalendar (iCal/.ics) feed. The change is part of a broader Planner overhaul Microsoft will begin deploying between mid‑January and mid‑February 2026, and it affects Planner in Teams desktop/web, Planner on the web, and related integrations. The removal of iCalendar feed support means users and organizations that relied on subscribing to Planner tasks from Outlook, Apple Calendar, Google Calendar or other iCal‑compatible apps will need to change how they surface tasks on external calendars.
Strengths of Microsoft’s approach:
Administrators should urgently inventory Planner→calendar usage, communicate the timeline, and select one of the practical replacement strategies described here. For teams without internal dev resources, Power Automate or a managed integration platform will typically be the quickest way back to calendar parity; for organizations that must preserve the subscription model, a lightweight Graph service providing an ICS endpoint is the most robust long‑term option.
The wider Windows and Microsoft 365 ecosystem continues to change rapidly — from Agenda/taskbar improvements to app consolidations around the new Outlook and Copilot integrations — and Planner’s changes are another reminder that a small, useful feature removed centrally can have outsized operational cost for downstream teams. Plan proactively, pilot replacements early, and use the January–February 2026 rollout window to validate and stabilize your chosen approach before the old feeds stop updating.

Background / Overview
Microsoft announced the Planner update and associated retirements through its Message Center item (MC1193421) and accompanying communications to admins and tenants. The update bundles new functionality — such as a revamped task chat experience and improvements aimed at premium plans — alongside the retirement of features that Microsoft says are underused, hard to maintain, or superseded by newer flows. The iCalendar feed integration is listed among the features that will be retired without replacement, meaning Microsoft does not plan to provide another built‑in Planner → calendar subscription equivalent at launch. This change arrives amid a string of product refinements across Microsoft 365 — including calendar and Outlook surface adjustments that have been restoring or reshaping quick‑glance calendar features on Windows — which places Planner’s retirement decision into a larger part in Microsoft’s productivity portfolio. Discussions about Agenda/Taskbar calendar restorations and the wider shift toward a Copilot/AI‑centric user experience have been active within the Windows ecosystem and community forums.What Microsoft is retiring (the headline items)
The Planner update will remove or change the behavior of several features. Key retirements and temporary unavailability items include:- iCalendar feed integration (iCal/.ics subscription): Retirement of the ability to publish a Planner plan or “Assigned to me” tasks as an iCal feed that subscribers could add to Outlook, Google Calendar, Apple Calendar, and other calendar apps. After the change, users will not be able to create new iCal feeds and previously created feeds will stop receiving updates.
- Prior task comments (basic plans): The legacy task comments pane will be replaced by a new Task chat experience; comment display and notification behavior will change. Email notifications for old comments will be altered; comments will be redirected to the new chat surface and viewers may be taken to Outlook for certain comment histories.
- Whiteboard tab for premium plans: The automated whiteboard tab that created a linked whiteboard and converted sticky notes into Planner tasks will be retired. Existing whiteboard content remains available in the Whiteboard app, but the “create task from whiteboard” convenience will disappear.
- Planner component in Loop pages: The /planner Loop component will be retired and replaced by the Task List control recommendation; existing components will render a link to the plan instead.
- Conversion of basic plans to premium plans (temporary pause): The conversion workflow will be temporarily unavailable during rollout; administrators and users will need to manually create a new premium plan and copy tasks until the feature returns.
Why the iCal removal matters (practical user impact)
The iCalendar feed has been a simple, broadly compatible way for individuals and teams to keep Planner dates visible in their day‑to‑day calendars. Use cases that will be affected include:- Viewing all assigned Planner tasks inside Outlook or mobile calendars without switching apps.
- Sharing a single subscription link with assistants, contractors, or external stakeholders so they can see Planner milestones in their calendars.
- Surfaceing Planner due dates in platform‑wide calendars used for personal time blocking or cross‑tool scheduling.
What Microsoft says: timing and scope
- Rollout window: mid‑January to mid‑February 2026 for the Planner update and related retirements. Microsoft’s Message Center entry and partner summaries use this exact window; organizations should expect the changes to begin rolling during that period.
- No replacement: Microsoft has explicitly stated there is no direct replacement for the iCalendar feed at this time. That means customers must plan for alternative integrations if they want calendar visibility after the retirement.
- Auto rollout: These changes are tenant‑wide and occur automatically; administrators will not need to flip a toggle to apply the retirement. However, communication and user guidance are the admins’ responsibility.
Immediate actions for administrators and teams (priority checklist)
- Inventory usage — Identify who and which processes rely on Planner iCal feeds. Search internal docs, support tickets, shared calendars, and public/guest calendars that might consume Planner feeds.
- Export or capture existing feeds — For any critical feeds, capture the current .ics URL and document which users/auto‑syncs rely on it. Note that Microsoft warns existing iCal feeds will stop being updated after retirement; proactively warn consumers to unsubscribe.
- Communicate timelines — Announce the retirement window and the practical effects to affected teams with concrete dates and recommended workarounds.
- Assess integrations and automations — Identify Power Automate flows, Zapier/Relay/other third‑party automations, or custom scripts that rely on Planner iCal feeds and plan replacement approaches.
- Plan replacements or build custom syncs — If calendar visibility must be preserved, consider the following technical alternatives (detailed in the next section): Power Automate flows to create calendar events from Planner tasks, custom services calling Microsoft Graph to generate calendar events or an ICS feed, or third‑party integration platforms.
- Update documentation and training — Ensure internal KBs, onboarding materials, and shared team pages reflect the change and instruct users how to add Planner tasks to calendar views using any new process you adopt.
- Pilot alternative flows — Before broad rollout, trial any Power Automate or Graph‑based solution with a small set of plans and users to validate duplication avoidance, event updates, and timezone handling.
- Monitor Microsoft communications — Watch the Microsoft 365 admin center and Message Center updates in case Microsoft publishes additional guidance, policy knobs, or a future replacement.
Practical alternatives and workarounds
There is no single drop‑in replacement from Microsoft, but several viable approaches will let organizations preserve Planner→calendar visibility.- Power Automate: build a cloud flow per plan (or a flow with plan‑ID branching) that triggers on new/updated Planner tasks and creates/updates events in an Outlook calendar. This approach provides fine control over mapping fields (start/end times, categories, attendees) and can avoid duplicates with a small state table or ID tagging strategy. Microsoft Q&A posts and community answers document workable templates and show how to set Start/End times and categories in Outlook events based on Planner task properties. Power Automate is a practical no‑code/low‑code alternative for many organizations.
- Microsoft Graph API: build a lightweight service that queries Planner tasks via Microsoft Graph, converts them to calendar events, and either writes events into an Exchange calendar or serves an .ics feed to subscribing clients. This is the most flexible option and preserves a publish/subscribe model for third parties, but it requires development effort and infrastructure to host and refresh the feed. Graph allows granular filtering (assigned‑to, plan id, due date windows), so it can replicate the old iCal behavior if your team invests in a small integration service.
- Third‑party integration platforms: Zapier, Relay.app, and similar automation services can map Planner triggers to Outlook/Google Calendar actions. These platforms abstract some of the complexity and may be preferable for organizations without internal development capacity. Evaluate these for pricing, security posture, and enterprise‑grade connectors.
- Manual export/import: For one‑time needs, users can export tasks or manually copy key dates into calendars. This is not a scalable solution but may suffice for small teams or short windows of disruption.
- Use Planner “Assigned to me” → Add to Outlook (while still available): Microsoft support documentation shows how users could publish their "Assigned to me" tasks as an iCal link today; if your tenant still supports creating feeds before retirement, consider creating and distributing any critical feeds as an interim measure while you build a replacement. Note that Microsoft’s retirement plan indicates new feed creation will stop within the January–February 2026 window, so this is only a temporary mitigation.
Technical and UX caveats to consider
- Duplication risk: Many naive flows create duplicate calendar events when tasks change state (e.g., due date updates). Design flows or services to compare by Planner task ID (store the Planner task ID in the calendar event body or metadata) so updates patch the existing event rather than create a new one. Power Automate and Graph both allow storing identifiers to enable idempotency.
- Timezone handling: Planner tasks may not always have full start/end zone metadata. Robust conversions should coalesce start times (or fall back to due date minus a default duration) and normalize to the calendar timezone to avoid incorrect scheduling. Examples in community guidance show expressions and fallback formulas for this exact problem.
- Mobile parity: If you depend on mobile calendar apps subscribing to an .ics URL, a Graph‑hosted ICS endpoint or a relay platform that produces stable subscription URLs is the safest way to preserve mobile subscriptions. Direct Power Automate flows that create Outlook events result in individual calendar events — good for one‑to‑one mapping but not ideal if you relied on a single subscribed calendar URL.
- Permissions and security: Any custom service that exposes an .ics feed must be secured appropriately if it reveals sensitive task metadata. Microsoft’s documentation warns that iCal links are accessible by anyone with the link; custom solutions must be designed with authentication or tokenized feeds where needed.
Broader product context and critical analysis
Microsoft frames this update as part of a Planner modernization that adds new features while removing low‑usage or duplicative functionality. That tradeoff is familiar across SaaS products: focusing engineering resources on higher‑value features sometimes means removing legacy connectors that are expensive to maintain.Strengths of Microsoft’s approach:
- Centralized modernization: The update consolidates premium and basic plan capabilities and moves toward a more unified Planner experience in Teams and on the web. Breaking out the new Task chat and investing in premium plan parity may improve collaboration flows for many teams.
- Clear timeline: Microsoft has published a predictable rollout window and Message Center item, giving admins time to plan.
- Loss of a simple, universal integration: The iCal feed was frictionless for end users and external collaborators; its removal without a direct replacement forces organizations to build or buy a solution. That matters especially for small teams and individual users who lack automation resources.
- Fragmentation and unequal alternatives: Premium plans and Project integrations already show different behavior in Planner/Power Automate tooling. Some premium plans previously lacked the same add‑to‑calendar options or Power Automate visibility, so parity may stay uneven and complicate enterprise automation. Community threads show premium/basic plan differences are ongoing admin issues.
- Potential for increased admin overhead: Administrators will need to fie, approve new automation tools, and document replacement workflows — work that is real and time consuming for IT teams.
Recommended migration plan (practical, sequenced)
- Immediately identify the top 3–5 business processes that must preserve Planner→calendar visibility (e.g., shared client calendars, field scheduling, executive assistant views). Document owners and SLAs.
- For each process, choose one of three replacement paths:
- Power Automate flow that creates/updates events (fastest, low‑code).
- Graph‑backed ICS relay (best for maintaining a single subscribed calendar URL).
- Third‑party iPaaS (Zapier/Relay) if you prefer vendor‑managed connectors.
- Build a small proof of concept on a sandbox plan:
- Create a flow that triggers on Planner task create/update.
- Map task fields to calendar event fields.
- Ensure event body stores the Planner task ID for idempotent updates.
- Pilot with 1–2 teams for 2–4 weeks, validate update behavior (due date changes, completion, reassignment), timezone correctness, and duplicate suppression.
- Iterate, expand rollout, and communicate changes to users with explicit unsubscribe/resubscribe instructions for old .ics feeds where necessary.
- Decommission or reconfigure any legacy dependencies once the replacement is stable.
Final assessment and conclusion
Microsoft’s early‑2026 Planner update is a mixed bag: it advances Planner’s collaboration model and adds new experiences, but it also removes convenient integration points — most conspicuously the iCalendar feed — that many users relied upon for effortless calendar visibility. The removal is not technically surprising given Microsoft’s product consolidation and investment priorities, but it is a substantive functional regression for a subset of users and organizations.Administrators should urgently inventory Planner→calendar usage, communicate the timeline, and select one of the practical replacement strategies described here. For teams without internal dev resources, Power Automate or a managed integration platform will typically be the quickest way back to calendar parity; for organizations that must preserve the subscription model, a lightweight Graph service providing an ICS endpoint is the most robust long‑term option.
The wider Windows and Microsoft 365 ecosystem continues to change rapidly — from Agenda/taskbar improvements to app consolidations around the new Outlook and Copilot integrations — and Planner’s changes are another reminder that a small, useful feature removed centrally can have outsized operational cost for downstream teams. Plan proactively, pilot replacements early, and use the January–February 2026 rollout window to validate and stabilize your chosen approach before the old feeds stop updating.
Summary checklist (one‑page):
- Inventory public .ics feeds and consumers now.
- Capture temporary exports for critical calendars.
- Decide replacement path: Power Automate / Graph ICS / Third‑party.
- Build, pilot, then roll out replacement flows before mid‑Feb 2026.
- Communicate changes to users and update internal docs.
