Frequently asked questions

Everything you need to know about connecting iCloud Calendar with Microsoft To Do.

What do I need to connect iCloud Calendar with Microsoft To Do?
You need an iCloud account with Calendar enabled and a Microsoft account (personal Outlook.com or work/school Microsoft 365). For iCloud, you'll need to generate an app-specific password in your Apple ID settings. Morgen Pro is required for task integrations—14-day free trial available.
Does this work with both personal and work Microsoft accounts?
Yes, Morgen supports both personal Microsoft accounts (Outlook.com, Hotmail) and organizational accounts (Microsoft 365, Azure AD). You can connect multiple Microsoft accounts if needed to separate work and personal tasks.
Can I use this if I don't have Apple devices?
Absolutely. While iCloud Calendar is designed for Apple devices, Morgen provides full iCloud access on Windows, Linux, and Android. You can schedule Microsoft To Do tasks to iCloud and access them from any platform through Morgen.
Do my Microsoft To Do subtasks sync properly?
Yes, Morgen imports your complete Microsoft To Do task hierarchy, including subtasks and their parent-child relationships. You can schedule individual subtasks as separate calendar events while maintaining the project structure.
How often do changes sync between the two apps?
Task status changes (complete/incomplete) sync in real-time. New tasks and due date changes sync every few minutes. iCloud calendar events sync within 4 hours, with local changes appearing immediately in Morgen.
Can I schedule tasks to other calendars besides iCloud?
Yes, if you have multiple calendars connected to Morgen (Google Calendar, Outlook, etc.), you can schedule Microsoft To Do tasks to any of them. iCloud is just one option in your unified calendar view.
What happens if I delete a scheduled task?
If you delete a calendar event that was created from a Microsoft To Do task, the original task remains in Microsoft To Do—only the calendar event is removed. This prevents accidental loss of task data.
Is my data secure with this integration?
Yes, Morgen uses industry-standard OAuth 2.0 for Microsoft To Do (no password sharing) and CalDAV with app-specific passwords for iCloud. Your credentials are encrypted and stored securely. Morgen never has access to your main iCloud password.
