The user wants to know how to add a secondary owner account to an existing Microsoft To Do personal workspace for shared access and management.

How to Add Another Owner Account to Microsoft To Do

Product: Microsoft To Do
Device & OS: not provided
Scenario: Managing task access, sharing lists, and configuring account permissions for collaboration.
Observed behavior: Microsoft To Do does not natively support adding multiple owner accounts to a single personal workspace.

Before you start

Ensure you are logged into your primary Microsoft account. Because personal workspaces cannot have multiple owners, you will need to utilize list sharing or data backups as a workaround.

Share Specific To Do Lists with Other Accounts

Instead of adding a co-owner to the entire workspace, you can share individual lists to collaborate on tasks effectively.

While Microsoft To Do limits personal workspaces to a single owner, the built-in sharing feature allows you to grant full editing access to specific lists. This is the best method for collaborative task management.

Select the list

Open Microsoft To Do and navigate to the specific list you want to collaborate on.

Access sharing options

Click or tap the 'Share' icon located at the top right corner of the list view.

Create an invitation link

Select 'Create invitation link' to generate a unique sharing URL.

Send the link

Copy the link and send it to the person you want to collaborate with. They can join and edit tasks using their own Microsoft account.

Share Specific To Do Lists with Other Accounts

Collaboration Note: Anyone who joins the shared list will be able to add, edit, complete, and delete tasks within that specific list.

Solution 2

Consult the Microsoft To Do Community for Advanced Support

For complex account recovery, organization-level configurations, or specific workspace access requests, consult the dedicated Microsoft forums.

Solution 3

Export and Backup Your Task Data Manually

If you are trying to move ownership because you are migrating to a new primary account, you should manually backup your task data.
