Unable to share Lists between users in same organizatoin

[TimM1]

We are unable to share lists between users. I understand that recent changes have put a stop to sharing between personal and work accounts, but it seems the same restrictions are in place for users in the same organization. 

I have tried to open a MS Support case but it was closed without any attention. 

Any suggestions or comments from a MS Rep would be appreciated.

Hey @TimM1

Sorry for inconvenience caused.

I am Chakresh, representing To Do engineering team at Microsoft. Can you help me with 

user-id and session-id for both of users, who is the owner of list and user who is trying to join the list.

User-id and session-id, are available in settings in To Do Apps.

Regards,

Chakresh

Hi @Chakresh633,
Thanks so much for coming back to me.
Forgive me for being a little cautious. Your user profile was only created yesterday and has no posts or replies except for this one. So I'm not comfortable with sending IDs etc to you.

If you are a MS engineer, could you please review my open tickets and respond through that channel instead?:
