You have a Microsoft 36S subscription. The subscription contains users that use Microsoft Outlook 2016 and Outlook 2013 clients. You need to implement tenant restrictions. The solution must minimize administrative effort. What should you do first?
A.

B.

C.
Upgrade all the Outlook clients to Outlook 2019.
D.

Tenant Restrictions in Microsoft 365 are designed to prevent users from accessing external tenants while allowing access to approved tenants. According to the SC-300 exam material and Microsoft’s Tenant Restrictions documentation, only modern authentication–capable clients (OAuth 2.0) can enforce tenant restrictions.
Outlook 2013 by default uses basic authentication , which does not support tenant restrictions . Outlook 2016 (and later versions) use modern authentication , making them compatible.
Microsoft Documentation: “Tenant restrictions require modern authentication to enforce access control. Legacy clients like Outlook 2013 must be upgraded to Outlook 2016 or newer.”
