Enter a valid user error on MS Stream

[Roli307]

Greetings,
We have two office 365 Tenants: A and B. The MS Stream channel was created on A as company wide. However users on tenant B can not be invited. If I try to invite I get the infamous please "enter a valid user error". How do I do that?
We have Azure AD.

Thanks in advance

Hi Adalton,

Users outside your organisation and guests cannot see your videos at the current time. That is a limitation of stream

That functionality is arriving in Q4 CY2020 in other words winter. you can see the roadmap item on the Microsoft 365 roadmap just search for Stream Anonymous

Hope that answers your question

Best, Chris
