How Does Office 365 Tenant Switcher Work?

Office 365 Tenant Switcher relies on Microsoft’s secure authentication framework. It ensures a smooth switching experience between accounts/environments for guest users and partner admins.

Additionally, it maintains serious data boundaries. It means traversing through accounts does not mix your data/permissions between organizations. It only allows one active account per tab at a time.

However, it functions differently based on your role and application.

For Partner Administrators & MSPs

As mentioned above, MSPs and IT admins can easily switch & manage a number of customer tenants using a single Microsoft 365 Admin center. To make it work, you only require delegated administration privileges (DAP). Next, you will notice a directory switcher at the top left of your home page.

For Guest Users (Microsoft Teams)

When guest users are invited to collaborate in another organization’s workplace (such as Microsoft Teams), the Office 365 tenant switcher functions via cross-tenant synchronization and Entra ID (Azure AD B2B).

It simply links your primary account to the secondary tenant’s Active Directory as an external user.

So, to jump into the guest tenant, you can click the organization drop-down (next to your profile picture. The system will verify your credentials and sign you into that workspace without ending your primary session.
