I'm trying to run

OUTLOOK_LIST_TO_DO_LISTS

and am getting a 403 - Forbidden. Codex says: > The Outlook connection itself is active for ; the failure is specifically permission/access to Microsoft To Do lists. Why does this tool return a 403 when other Outlook tools work?

Hi there, You're right that the connection itself is fine. The 403 is a scope issue:

OUTLOOK_LIST_TO_DO_LISTS

needs a Microsoft To Do permission (

Tasks.Read

or

Tasks.ReadWrite

), and our default Outlook scopes don't include any

Tasks.*

scope, so your connection was never granted Tasks access. Your mail and calendar tools work because those scopes are in the default set. To fix it: • Open your Outlook auth config and add

Tasks.ReadWrite

to the scopes (you can add

Tasks.Read

too). • Use the short name

Tasks.ReadWrite

, not the full

https://graph.microsoft.com/Tasks.ReadWrite

URL. Our Outlook config uses the short Graph permission names. • Save, then disconnect and reconnect the Outlook account so Microsoft re-issues consent with the new permission. After reconnecting,

OUTLOOK_LIST_TO_DO_LISTS

should return your lists. If you're on a setup where you can't edit the scopes yourself, just reply here and we'll add it on our side, then you can reconnect.
