stickers not showing on Microsoft To Do icon (macOS)
macOS 26.5.1 MS To Do 2.169 There is no stickers on icon in my mac, but in iOS on the same account - I have it. Already reinstall app, check notifications settings - nothing helps. Who know, how to fix the problem?art_skJul 05, 2026Copper Contributor31Views0likes2CommentsCreate a 'My week' just like 'My day'
There is an other request (https://techcommunity.microsoft.com/t5/microsoft-to-do/feature-request-add-to-my-day-tomorrow/m-p/1930251) to create 'My Tomorrow' section, but for me it would be more useful to create a plan for the week and generate the 'My day' content from there. The 'My week' would include elements that I want complete or focus during the workweek. 'My week' could be the name, but it is more like a container that can gather elements from multiple lists to show what is my current focus for a longer period than 1 day.Tibor_WeberJul 04, 2026Brass Contributor9.6KViews31likes5CommentsAll my unassigned tasks vanished overnight
Hi, about 300 of my unassigned tasks -those not on lists- vanished overnight. All of them. My tasks on lists seem to be all there. The previous day, I was doing cleaning on that list, since the android app stopped synching, and it was sluggish before that. I had over 50000 completed tasks on that list. I moved those 300 uncomplete tasks to a temporary list, deleted all completed tasks, then moved those 300 back, and deleted the temprorary list. I most definitely did not delete those 300 tasks in question, and I checked hours before going to bed and going to bed that on my phone, in the desktop app and in my desktop browser they were all present and in synch, and addings tasks was very snappy and synched across devices. Official chat was completely useless and I couldn't even reach or be connected to anybody in the correct department after banging my head against a wall for an hour. I have little hope of fixing this, but is there anything I can do, or should I just finally bail out of using this buggy mess of a software?

--- # 📄 **Technical Report: Persistent Outlook Web App Sync Failure Affecting Microsoft To Do / Outlook Tasks Ecosystem** **Issue Duration:** At least 3 months probably more **Platforms Affected:** - Microsoft To Do (Android) - Outlook Tasks (Windows Desktop Outlook) - Outlook Tasks (Outlook Web App) - Exchange Online (backend sync service) --- ## 1. **Executive Summary** I have experience **persistent, intermittent, and platform‑specific synchronization failures** within the Microsoft To Do / Outlook Tasks ecosystem. The critical finding is: ### **The Outlook Web App is often isolated and does not sync with any other platform.** Meanwhile: - **Windows Desktop Outlook ↔ Android To Do sync perfectly in both directions.** - **Outlook Web App ↔ (Desktop / Android)** do not sync. This isolates the issue to the **web app’s sync pipeline**, not the task data, not the account, and not the other apps. The failures present as: - **“Synchronization in progress”** stuck indefinitely - **“Synchronization failed”** when manually attempting sync - Web app showing **stale, outdated, or incomplete task lists** - Web app failing to send or receive updates from Exchange Online The same tasks that fail to sync for hours later sync successfully without any modification, proving the data is not corrupted and the failure is backend‑related. --- ## 1.1 **Cross‑Platform Sync Behavior (Critical Diagnostic Insight)** ### ✔ **Windows Desktop Outlook ↔ Android To Do** - Full two‑way sync - Immediate updates - Reliable and consistent ### ✖ **Outlook Web App ↔ Desktop Outlook** - No sync in either direction ### ✖ **Outlook Web App ↔ Android To Do** - No sync in either direction ### ✖ **Outlook Web App ↔ Exchange Online** - Appears to be failing or stalling This proves the web app is **not participating in the sync ecosystem**. --- ## 2. **Symptoms Observed** ### 2.1 **Outlook Web App** - Sync button stuck on **“Synchronization in progress”** for hours - Manual sync results in **“Synchronization failed”** - Web app shows outdated task lists - Web app does not receive updates from desktop or mobile - Web app does not send updates to desktop or mobile ### 2.2 **Android To Do** - Tasks created on Android do not appear in the web app - Tasks created in the web app do not appear on Android - Edits fail to propagate to the web app - Manual sync does not resolve the issue - Logout/login sometimes helps, inconsistently ### 2.3 **Windows Desktop Outlook** - Syncs perfectly with Android - Does not sync with the web app - Shows correct, up‑to‑date task data ### 2.4 **Platform Sync Matrix** | Action | Desktop Outlook | Android To Do | Outlook Web App | |--------|-----------------|---------------|------------------| | Create/edit task on **Desktop** | ✔ Syncs to Android | ✔ | ✖ No sync to Web | | Create/edit task on **Android** | ✔ Syncs to Desktop | ✔ | ✖ No sync to Web | | Create/edit task on **Web** | ✖ No sync to Desktop | ✖ | ✔ Stays only on Web | **Conclusion:** The Outlook Web App is **fully isolated** from Exchange Online’s task sync pipeline. --- ## 3. **Troubleshooting Steps Already Attempted** ### 3.1 **Web App** - Hard refresh (Ctrl + Shift + R) - Full browser cache clear - Logout → close browser → reopen → login - Switching lists to force metadata reload - Creating tasks to trigger sync events - Deleting tasks to force backend updates ### 3.2 **Android** - Manual sync - Clear cache - Logout/login - Device restart - Network switching - Creating/completing tasks to trigger sync ### 3.3 **Desktop Outlook** - Verified account health - Verified Exchange Online connectivity - Verified task folder integrity ### 3.4 **Account / Backend** - Verified Microsoft Account stability - Verified no multi‑account conflicts - Verified Exchange Online service health None of these steps produce consistent or lasting resolution. --- ## 4. **Frequency and Pattern** - Occurs multiple times per week - Occurs regardless of recent task edits - Occurs across multiple browsers - Occurs across multiple Android versions - Sync resumes randomly after hours - Sync resumes without any data changes - Sync resumes after logout/login, but inconsistently This pattern strongly suggests **backend sync token stalling**. --- ## 5. **Technical Analysis** ### 5.1 **Two‑Way Sync Failure Confined to Web App** Because: - Desktop ↔ Android works - Web ↔ (Desktop / Android) fails The failure is isolated to the **web app’s connection to Exchange Online**. ### 5.2 **Sync Token Stalling (Most Likely Cause)** Symptoms match known sync token stall behavior: - Endless “Synchronization in progress” - Manual sync fails - Sync resumes randomly - Sync resumes after forced metadata refresh - Sync resumes after unrelated actions (e.g., completing a task) ### 5.3 **Not a Corrupted Task Issue** Because the same tasks later sync successfully: - No malformed tasks - No unsupported metadata - No blocked sync queue - No corrupted lists ### 5.4 **Backend Sync Pipeline Instability** The pipeline: **Web App → Microsoft Sync Service → Exchange Online → Desktop / Android** appears to be failing at the **first hop** (web app → sync service). ### 5.5 **Web App Lacks Retry Logic** The web app provides: - No manual retry - No way to cancel a stuck sync - No way to reset sync session - No way to regenerate sync token Thus, when the backend stalls, the web app remains stuck indefinitely. ### 5.6 **Android Background Sync Not the Cause** Android is syncing perfectly with desktop Outlook, proving Android is not the source of the issue. ### 5.7 **Web App Sync Isolation (New Insight)** The web app is the **only** platform failing to communicate with Exchange Online. This is now clearly a **web‑app‑specific sync session failure**, not a multi‑platform issue. --- ## 6. **Impact** - Tasks frequently out of sync - Web app becomes unusable for task management - Daily workflow disrupted - Manual intervention required multiple times per week - Task state inconsistent across platforms - Reduced confidence in Microsoft To Do as a reliable ecosystem --- ## 7. **Requested Assistance** ### 7.1 **Engineering‑Level Investigation** Specifically into: - Outlook Web App sync token behavior - Web app → Exchange Online sync session stability - Backend retry logic - Web app sync error handling - Web app task API connectivity ### 7.2 **Diagnostic Tools** If available: - Sync session logs - Sync token status - Task metadata inspection tools - Backend queue visibility - Error codes beyond “Synchronization failed” ### 7.3 **Known Issues** Requesting documentation on: - Known To Do / Outlook Web sync token stalls - Known Exchange Online sync delays - Known intermittent sync failures - Known web app pipeline instability ### 7.4 **Confirmation Whether This Is a Known Issue** Given the duration and reproducibility, this appears to be a **backend‑level web app sync failure**. ### 7.5 **Request for Web App Sync Session Reset** Specifically: - Manual reset of the web app’s sync session - Forced regeneration of sync token - Flush of stuck sync queues - Verification of web app’s Exchange Online connectivity --- ## 8. **Evidence Available** I can provide: - Screenshots of “Synchronization failed” - Screenshots of “Synchronization in progress” - Timeline of sync failures - Android device logs - Browser console logs --- ## 9. **Conclusion** This is a **persistent, platform‑specific sync failure** affecting only the Outlook Web App. Desktop Outlook and Android To Do sync perfectly, proving the backend and data are healthy. The web app is isolated and failing to communicate with Exchange Online. I am requesting **engineering‑level support** to reset or repair the web app’s sync session and investigate the underlying cause. ---Solvedcurtis00000001Jul 01, 2026Tin Contributor41Views0likes1CommentIssue: The "My Day" side pane in Outlook calendar web not showing assigned tasks added to My Day
I want to use the neat drag-and-drop feature announced here for tasks assigned to me in Planner. Steps to recreate: In Planner, a task gets assigned to me In the To Do web app, I can see this task in "Assigned to Me", add it to "My Day" In the To Do web app, the task is now in "My Day" Actual behavior: The assigned task added to "My Day" in To Do web is not shown in the Outlook Web "To Do - My Day" side pane. Expected behavior: In the outlook calendar web app, I should be able to see this "assigned" task added to "My Day", in the side-pane which allows drag and drop. Better yet, the "assigned to me" list could show up as one of the "To Do" dropdown options. Because of this issue, I am not able to time-block for tasks assigned to me from Planner. Same problem found here: https://answers.microsoft.com/en-us/msoffice/forum/all/help-showing-my-planner-tasks-in-the-my-day-pane/430855d3-1da8-4244-aa86-8e91272818c8 This is definitely a loose thread in the feature. Any idea if this could be implemented? Or how to get this feedback through to Microsoft? Thanks!

A few months ago, something happened to my instance of Microsoft To Do. The "Details Panel" (I think that is the name) that appears on the right side of the screen when a task is selected is too narrow to even accommodate words more than a few letters long. (See photo) The only way I know to adjust this is to place the pointer along the border between the Details Panel and the Task List until it becomes a double arrowhead. However, while this feature ought to permit me to adjust the width of the Details Panel, it is now non-functional. Does anyone have any idea how can I fix this?remcnultyJun 19, 2026Copper Contributor764Views1like3CommentsGraph API 1.0 - Listing lists doesn't return all lists (todoTaskList)
Hi, first time posting here, please let me know if I should be doing something differently! I've searched throughout the internet and couldn't find a reason for this. I've got a couple of users running into a problem where the https://learn.microsoft.com/en-us/graph/api/todo-list-lists?view=graph-rest-1.0&tabs=http endpoint only returns one list (Flagged Emails), though these users have and see many other lists in the To Do desktop (macOS) app. I've confirmed in both cases it's the same user that's identified in my app/integration and in the desktop app. They can see the tasks in that list without a problem. There are no errors requesting that list, and asking via `/users/{id|userPrincipalName}/todo/lists` also returns the same response (with that one list). Is there any known situation where this could be happening? Am I missing something obvious? Is there something else I should be trying? I've got many other customers using the To Do integration without a problem. I'm aware "My Day" and a few other special lists aren't returned. Thank you so much!Microsoft TO DO language Change

if I insert a pic from clipboard (source Irfan-view) the size in Microsoft ToDo is always up to 5 times greater then the saved picture to Filesystem. If I insert the pic from Filesystem, all good. Copy/Paste must be have a bug in MS-ToDo. e.g. 100KB-File pasting it shows and uses 1MB.HTD467886May 29, 2026Copper Contributor16Views0likes0Comments
