Sharing lists with others outside your organization
Thanks Dan, your ability to do this must have something to do with your organizations security settings.
I can add the personal list to my corp account and it will be listed there but it does not update.
Never moves past getting list ready. Thanks for sharing.
TQFordYes, I'm the admin (and only member of my org actually 
) and don't have any restrictions sharing externally.
I see others get stuck on "getting list ready" too (despite being allowed to share externally) - in https://answers.microsoft.com/en-us/msoffice/forum/all/microsoft-to-do-for-outlook-365-is-stuck-in/ce0e38a7-4b22-4014-90d0-cc245f84658a I found they managed to clear it by moving the order of the tasks in the personal account which seemed to force a sync with the org account.
In https://answers.microsoft.com/en-us/msoffice/forum/all/trouble-sharing-a-personal-todo-list-to-a-business/0444e8d2-fefe-41d7-aceb-82f744375790, they set up the link via the https://to-do.office.com and using the browser's "icognito" mode - I'm guessing that forced a "clean" log in to each account perhaps...
Even if either trick does somehow magically fix things, researching these threads it does all seem a bit flakey... 
All the best,
Dan
