DueSlotFrequently asked questions
What happened to Planner's Outlook calendar feed?
Microsoft retired Planner's “Add plan to Outlook calendar” iCalendar feed in January–February 2026 (message centre MC1193421), with no replacement from Microsoft. DueSlot is a separate product that creates a calendar in your own mailbox and keeps one event per Planner task up to date.
Which accounts work?
Microsoft 365 work or school accounts only. Planner isn't available on personal Microsoft accounts, so DueSlot isn't either.
Which Planner plans can you read?
Basic plans only. Microsoft Graph has no API for Premium Planner plans, which is the same limit the retired feed had.
Do you store my task titles?
No. Task titles go from Microsoft Graph through our Worker in memory and into the calendar in your mailbox. We store only identifiers, keyed hashes, due dates and your encrypted Microsoft refresh token. See the privacy policy.
What permissions do you ask for?
Sign-in and a basic profile (User.Read), reading your Planner tasks (Tasks.Read), creating and updating one calendar called “Planner (DueSlot)” in your own mailbox (Calendars.ReadWrite), and staying signed in for background sync on Pro (offline_access). We never write to any other calendar.
What is on the Free plan?
Manual “Sync now” (up to six times an hour) for tasks assigned to you, and a one-off .ics download. Background sync every 30 minutes, filters and reminders are Pro.
What does Pro cost?
Pro is $2.99 per user per month or $24 per user per year. Team ($19 per month or $180 per year, up to 10 users, whole-plan calendars) is planned for a later phase and isn't for sale yet. Prices are in US dollars and exclude VAT or sales tax where it applies. Checkout stays closed until billing is switched on.
Can my organisation get DueSlot for free?
Noscotek accounts, including guest users in that tenant, already receive Pro (complimentary). There is nothing to buy. Complimentary Pro is granted only by matching the verified Microsoft tenant id, never an email domain.
Will you change my existing meetings?
No. DueSlot only creates, updates and deletes events inside the “Planner (DueSlot)” calendar it creates. If that calendar is missing, we stop and ask you before creating it again.
Is this an Outlook add-in?
DueSlot is a web app at dueslot.nostello.com. An optional Outlook pane is planned; it is not submitted to AppSource yet.
