Microsoft To Do Sharing Failure Between Personal Accounts – Support Escalation Needed

I am experiencing exactly the same issue with Microsoft To Do list sharing.

I am a paying Microsoft 365 Family subscriber with an annual subscription.

Previously, I was able to share lists successfully with other personal Microsoft accounts. However, I can no longer share additional lists, either with people I previously shared lists with or with completely new users.

All accounts involved are personal Microsoft accounts, not work or school accounts.

I have also made several attempts to contact Microsoft Support:

1. I emailed the Microsoft To Do feedback team but received no response.
2. I contacted Microsoft Support through live chat. The representative told me that Microsoft To Do was outside her department’s responsibility.
3. I requested escalation to the appropriate technical team, but the representative only provided a Microsoft Community link and closed the conversation before I could respond.
4. I called Microsoft Support, but the automated system did not understand my issue and only sent me a general help link.

This is extremely frustrating, especially as a paying Microsoft 365 Family customer.

I also found references to a previous Microsoft To Do sharing incident, MO1213801, reported in January 2026.

Could a Microsoft representative please clarify the following?

• Is Microsoft aware of the current list-sharing issue affecting personal accounts?
• Is this related to the previous incident MO1213801, or is it a new service issue?
• Has the issue been escalated to the Microsoft To Do engineering team?
• Is there an estimated timeframe for a fix?
• What is the official support channel for customers experiencing this issue?

This is not an isolated case. Multiple users are reporting the same problem.

We need an official acknowledgment, a proper investigation, and a clear update from Microsoft.

Thank you.
