To Do App Alternative that works directly with your M365 Account, for Classic Outlook Fans!
Hi Everyone I have built an app for you Classic Outlook task fans. My old favourite task app isn't being supported any more, so as a 20+ year Outlook and GTD veteran I decided to have a go myself and build something! Does your Todo crash because of too many completed tasks. Do you wish you could create views of your tasks including groups by category, priority, and filter by completed, due today, not dated Ability to use Classic Outlook "quick steps" style actions to tidy up your inbox Be able to print tasks in a lovely big old Outlook 97 style grid, direct from your phone Create tasks from emails, events from emails Keep your Outlook tasks perfectly intact and get going just by logging in to your M365 account?

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 02, 2026Copper Contributor45Views0likes2CommentsTasks sync failure - Outlook web vs mobile Outlook vs desktop Outlook
--- # 📄 **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progress”** stuck indefinitely - **“Synchronization failed”** when manually attempting sync - Web app showing **stale, outdated, or incomplete task lists** - Web app failing to send or receive updates from Exchange Online The same tasks that fail to sync for hours later sync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 Contributor69Views0likes1CommentAll 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?

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 Contributor19Views0likes0CommentsSorting tasks into lists from “All” on mobile
I am not sure if I’m missing something, but is there an easy way to add tasks to a list from the ♾️ All list? I like to add tasks there then be able to add them to lists - I’m hoping to long press and add it to a list or select a list from a drop down when I click into the task. I’m aware of the sorting feature where you select multiple and add them to a list, but that is cumbersome when you only want to add one task to a list.laurenkd89May 19, 2026Copper Contributor30Views0likes1CommentOverdue tasks no longer appear in red in light mode
Last week I noticed that the "Overdue [Date]" text in overdue tasks no longer appears in red. I use light mode, and if I switch to dark mode that text will appear in red, but it reverts to black when I turn dark mode off. This is happening in the web app and if I go to the app in Outlook, but is not an issue on the desktop app.edavisApr 20, 2026Copper Contributor264Views1like0CommentsColours within task notes
Hello, I noticed that when copying text from elsewhere, it does copy the colors, but I cannot find any way of replicating this myself. Are there tags or markers to use to be able to use colours (red or green or blue) when writing? It does seem like the notes can support them since they do stay without any issue when copied from elsewhere. Thanks for your helpLBouguetMar 10, 2026Copper Contributor41Views1like0CommentsTo Do: scrolling bug
You can’t scroll all the way down in longer notes anymore in the Android app. The keyboard covers part of the note. I already tried to update it an reinstall it. Many users have this problem. This makes the app almost unusable. I'm on OneUi 7. I attached a screenshot with a transparent keyboard.kopaturexMar 03, 2026Copper Contributor111Views0likes0Comments
