Thank you for posting your query on Microsoft Q&A. From above description I could understand that you want to add a user from different Azure AD tenant/ personal account to manage you IOT central app.
Please do correct me by responding in the comments section if there are any discrepancies.
- Yes you could add external user account including personal accounts .
- IoT Central supports Microsoft user accounts, Azure Active Directory accounts, Azure Active Directory groups, and Azure Active Directory service principals.
- Service principals and Active Directory groups must belong to the same Azure Active Directory tenant as the Azure subscription associated with the IoT Central application.
- In my tenant I added user from my live account and different subscription too.
Thanks,
