Dragging Task onto Outlook Calendar in Web does keep Category (color) (or notes or steps)
So categories could be useful. They have been added now to both the online ToDo app and Outlook Web Calendar. A great feature is in Outlook Calendar (web), you can choose from the top right the a ToDo list side menu and drag a task onto the calendar to make a quick 1/2 hour block and move it around. And you could color code this with categories. HOWEVER, they are not connected. If I choose a category (e.g. Purple) in ToDo and then drag onto the calendar the event does not have a category. I can add it AGAIN if I want or add a different one. (1) I noticed this drag and drop is one-way and any changes in the calendar are not reflected back onto the original task. Fine, you can fix that later, but (2) when I drag the task onto the calendar, why can't the category at least go with it? (3) I noticed the notes and steps don't translate either, but please, the category could be so useful.
Microsoft To-Do sync broken — Graph API returns 500 Internal Server Error on /me/todo/lists
Account: my personal microsoft account Issue: Microsoft To-Do has stopped syncing on all clients (web, Android app, Windows app) since approximately 2026-08-17 ~10:00 UTC. All clients show "syncing" indefinitely and never load any lists or tasks. What I've tested: To-Do Web UI (to-do.microsoft.com) — loads the shell but gets stuck infinitely. Browser DevTools show a 500 error on:The app cannot finish bootstrapping because of this failing endpoint. PATCH https://substrate.office.com/todob2/api/v1/settings/WunderlistImportStatus → 500 To-Do Android app — stuck on "syncing", never loads any lists. Microsoft Graph Explorer — GET https://graph.microsoft.com/v1.0/me/todo/lists returns: { "error": { "code": "UnknownError", "message": "", "innerError": { "date": "2026-08-17T14:49:16", "request-id": "1a8ecd9b-ad9d-4801-9f17-93d243ab6d7a", "client-request-id": "89c63f17-7b32-2cc8-df82-0712bd11e59f" } } } Other Microsoft 365 services — OneDrive works fine, test file synced. Account authentication is valid (Graph Explorer successfully queries /me). Re-login, account removal/re-add — tried on all clients, no change. No third-party integrations modified task data — verified via local opencode session database (zero Microsoft Graph/To-Do API calls found in any session). Never used any other 3rd party integration. Conclusion: The issue is a server-side error in the To-Do backend. The Graph API itself (/me/todo/lists) returns 500, and the substrate settings API also returns 500. This is not a client-side issue, not an authentication issue, and not caused by any third-party integration. The account-specific error suggests corrupted backend state or a service-side bug affecting this specific account. Request: Please investigate the server-side error for my account usinng the provided request IDs and restore To-Do sync access.MS To-Do app stops responding when on the 2d screen and being idle (not in focus) even a few seconds
In my case, there's laptop and an external monitor connected to it. MS To-Do app is always opened only in the external display. It's always in full screen. When I interact with the app (e.g., add a new task or adding info into an already created task), then switch to another app (e.g. Google Chrome on my main laptop's display) and then return back to the To-Do app, it stops responding COMPLETELY. Wherever I click on the app, it just won't react at all. The only way to bring in back to life is to kill it and relaunch again. But repeating this "kill-restart" cycle 50+ times EVERY SINGLE DAY is madness! Please fix this super-frustrating behaviour of the app ASAP!
Feature request: Add to My Day (Tomorrow)
I love the Add to My Day feature. I love that it disappears when the day is done. It's fantastic. But it only works for that day. I believe there is evidence that setting up a daily list the night before is more effective for productivity. I would like to request a feature for Microsoft To Do: Add to My Day (Tomorrow). This would be just like Add to My Day, except that the item would appear as already added to my day when tomorrow arrives. That's it. This is different from setting a due date of tomorrow. It's just putting it on tomorrow's My Day list. It may or not be due, but it's on the list.

Hi All, I have a question related to notifications of Outlook and To-Do when running on Windows 10 PC. As Outlook and To-Do are integrated on a M365 platform, To-dos appears as tasks in Outlook. When a reminder is triggered in MS To-Do I get a windows notification, which is what I expect, but I also get a Outlook notification for the same to-do but via Outlook tasks. Does anyone know a way around this duplicate alert that does not involve disabling Outlook notifications as a whole?Feature parity between Web and Desktop/Mobile TODO (Categories)
It looks like there isn't feature parity between the Web version of To Do and the Desktop/Mobile apps. Specifically, the web version has access to and displays UI components that allow us to select Categories to assign to our To Do items, yet this ability does not exist on the Desktop/Mobile Apps. Furthermore the display of assigned categories to Items created on the Web interface is not consistent on the Desktop/Mobile apps. The Desktop will show the category assigned to the item (but does not allow modification), however the Mobile App does not indicate any category assignment at all. Can we please get a feature parity w.r.t Categories between the Web, Mobile, and Desktop app of To Do ? Thank you.Tasks show up twice in To Do module in Outlook On Desktop
I have a strange problem with my tasks in the To Do module when it is used inside the Outlook app installed on my Windows PC. Some tasks show up twice there. When I check other places the task is listed only once there: On the To Do Webapp in the browser In the To Do App on my Android Phone When I start Outlook in the browser and check the To Do module there But on my Desktop in the Outlook App the task is listed twice. When I mark it a completed on my To Do app on my Android Phone one of the two task shown gets marked as completed (and is shown as completed in all three places mentioned above), however the other one stays in the not completed status. Triggering the Sync in the To Do module in Outlook does not solve the issue, restarting Outlook does not solve it as well. I have to delete the second task manually in the To Do module. This is really annoying because I get the reminder for a task from the outlook app on Windows but cannot really use Outlook to manage the task there. Does anyone else have this problem?
Make overdue tasks more visible
I'm a heavy user of To Do, and despite using it every day for several months, I just found the Overdue list under Planned. This is a really important list for me, but burying it here make it much less accessible and valuable. I'd like to recommend two possible approaches to make overdue tasks more visible: Add an "Overdue" smart list to the sidebar, at the same level as Important, Assigned to Me, etc. Have an option to show overdue tasks in My Day similar to the current option for Due Today tasks.
To Do SUCKS
I don't know who--or what team--designed To Do, but it is absolutely horrendous and is no replacement for Outlook Tasks, which gave you a FULL SCREEN to make notes, and it was easy to do (not pun intended) anything, but To Do opens a tiny window in the middle of the screen that CANNOT be resized, so you have a tiny, tiny pane on the right-hand side of this tiny screen to scroll up and down reading notes. It's beyond horrible. PLEASE, PLEASE, PLEASE can someone at Microsoft go back to the drawing boards and make an app that fills the whole screen, can be resized, and is easy to use?!
