Contoso plans to implement the following changes:
✑ For all new users in the on-premises organization, provide an email address that uses the value of the Last Name attribute and the first two letters of the First Name attribute as a prefix.
✑ Decommission the public folders and replace the folders with a Microsoft 265 solution that maintains web access to the content.
Contoso identifies the following technical requirements:
✑ All email messages sent from a SMTP domain named adatum.com must never be identified as spam.
✑ Any solution to replace the public folders must include the ability to collaborate with shared calendars.

✑ The principle of least privilege must be applied to all users and permissions.
✑ All email messages sent from an SMTP domain named com to contoso.com must be encrypted.
