Support

We answer within one business day (Europe/Tallinn and Africa/Johannesburg hours). Email support@noscotek.co.za. Please don't email task titles, calendar contents or tokens: describe the problem, and we'll ask for anything else we need.

Get started

1. Open dueslot.nostello.com and choose Sign in with Microsoft.
2. Use a work or school account. If sign-in asks for admin approval, send your admin the approval page.
3. Press Sync now to create “Planner (DueSlot)” and add events for tasks that have due dates.
4. In Outlook, tick that calendar if it isn't visible yet.

Upgrade or manage billing

Once checkout is open, use Upgrade or Manage billing on your account page. Complimentary Pro accounts have nothing to buy and won't see a billing portal.

Good to know

• Basic Planner plans only.
• Work or school accounts only.
• If a company network blocks dueslot.nostello.com, DueSlot can't load. Ask IT to allow it.
• Privacy questions: Sheldon Halgreen, privacy@noscotek.co.za.
