Problem Description: Join List Bug Please

There is an active bug right now with Microsoft Todo where people are not able to join a list they have been invited to. I am unable to submit a help ticket or talk to a support team directly (or am unable to find where to do so), so I am submitting/posting this here, in hopes of getting attention to the matter from the technical support team. **See other post(s) here: [https://learn.microsoft.com/en-us/answers/questions/5688092/to-do-app-cant-join-list?source=docs](https://learn.microsoft.com/en-us/answers/questions/5688092/to-do-app-cant-join-list?source=docs)** Note sure how long this has been a bug, looks like at least the 31st. My husband and I have been trying to share lists for about a day. Tried multiple times, incognito, etc. As others stated on that thread, this is clearly a bug. How / When can you get this resolved?

Quick Answer for Resolving File Sharing Problems

The issue with joining a list has been reported by many users and is recognized by the backend team.

Likely Causes Behind File Sharing Problems

• The Microsoft account or license context may not match the purchase or device.

• Cached credentials, outdated builds, or damaged local components can trigger file sharing problems.

• A file-specific corruption or add-in conflict can mimic a broader application failure.

Recommended Solution: Fixing File Sharing Problems Step by Step

When to use this: Apply these steps when the symptoms match and you can access the relevant Microsoft account or administrator.

1. There is no user-side fix available at this time.

2. Please be patient and wait for the latest update from Microsoft.

3. As community moderators, we have limited access to internal details and recommend monitoring for updates.

Alternative Solutions for When Office Still Fails

1. Retry the Microsoft-side steps after restarting the app and device.

2. Test the same action in a private browser session or a new blank file to isolate account vs file issues.

3. Capture exact error text and screenshots before contacting Microsoft Support or your administrator.

Working with WPS Office: WPS Office for Local Document Work

WPS Office cannot replace Microsoft account, activation, or cloud fixes for this scenario. It remains one of the best free Microsoft Office-compatible alternatives for opening and editing local files.

1. Download and install WPS Office from the official website.

2. Open local Word, Excel, PowerPoint, or PDF files in the matching WPS app.

3. Save a working copy locally while Microsoft-side issues are resolved.

4. Return to Microsoft Office after the primary fix succeeds.

If you need a practical local workspace in the meantime, try WPS Office.

Prevention Tips for Safer Document Habits

• Keep one primary Microsoft account for subscriptions and Office sign-in.

• Install updates for Office and Windows before retrying failed workflows.

• Back up important files before repair, reset, or reinstall actions.

• Work on copies and keep version history enabled when available.

FAQs About Common File Sharing Problems Answers

Can WPS Office fix this file sharing problems issue directly? Only when the WPS steps match the formatting or file task. Account, activation, and cloud issues stay on the Microsoft side.

Should I reinstall Office before trying these steps? Not first. Confirm account, license, and the exact error before reinstalling.

What should I send to Microsoft Support? The affected account email, device type, Office version, exact error text, and screenshots with personal data hidden.
