License for Multi Tenant Setup
Scenario: User R is part of Tenant A and have M365 License. Tenant A & B are cross sync. Whether User R would need M365 license from Tenant B to operate on files stored in Tenant B?
Scenario: User M is the external guest to Tenant B. Whether User M would need M365 license from Tenant B to operate on files stored in Tenant B?

rr_mstechnology Hi, as for User R who is part of Tenant A with an M365 license and accesses files in Tenant B, an additional license in Tenant B is not required if the user merely collaborates on files. In fact, synchronization between tenants allows users licensed in one tenant to access shared content in another tenant without requiring a duplicate license, as long as the user logs in as a guest or external user.
In contrast, for User M, who is an external guest in Tenant B, an M365 license from Tenant B is not required to access and collaborate on shared files. In fact, Microsoft 365 allows unlicensed external guests to perform basic collaboration tasks such as viewing, editing, or commenting on documents in OneDrive, SharePoint, and Teams.

What are the scenario is which User R would explicitly require license from Tenant B?
Can we allocate Onedrive for business in Tenant B for User R apart from his OneDrive for business from Tenant A? So that Tenant B data never leaves its premises. Is it a common scenario?rr_mstechnology User R, while already licensed in Tenant A, would need a separate license for Microsoft 365 in Tenant B if he were to perform activities or use services unique to Tenant B that exceed the normal collaboration capabilities provided for guests. Cases include:
-Administrative access
-Use of Power BI Pro
-Access to Microsoft Project.
-Advanced collaboration on Microsoft Teams.
-OneDrive for Business Separate in Tenant B: If the user requires separate OneDrive storage space in Tenant B, separate from Tenant A, a license in Tenant B is required to manage and access this additional space.
Separate OneDrive for Business in Tenant B for User R
It is possible to create a separate OneDrive for Business in Tenant B for User R, distinct from his OneDrive in Tenant A. However, this configuration requires the assignment of a Microsoft 365 license in Tenant B to activate and manage the storage. Although technically feasible, assigning a separate OneDrive in Tenant B for a user with a primary license in Tenant A is not very common.
Typically, organizations using inter-tenant sharing rely on default guest permissions, allowing licensed users in one tenant to access resources in another tenant without duplicating storage space.
