Can two users with the same email address be associated with two different Azure AD directories?

Question

I would like to understand how Azure Active Directory (Azure AD) handles users with the same email address across different tenants. Specifically, can two separate users with the same email (e.g., user@example.com) exist in two different Azure AD directories as distinct accounts?

For example:

Tenant A: A user user@example.com is created as a native member in Azure AD.

Tenant B: Another user with the same email (user@example.com) is created as a separate account in a different Azure AD directory.
