Changelog: We updated TLS cipher preference for SMTP (MMA-4475).

Also the Microsoft 365 sync wizard now shows which tenant the admin is connected to, and prevents accidentally connecting the admin to a different tenant, which would prevent access to the original tenant’s sync settings. We recommend using a sub-admin for each client, and configuring sync for the client tenant against the client sub-admin. See the success center for more details (MMA-4087, MMA-4012)
