What is required to configure mailboxes in Dynamics 365 Sales?

Configuring mailboxes in Dynamics 365 Sales necessitates email domain verification to ensure that the email addresses associated with the mailboxes are legitimate and properly linked to the organization. This process enhances security by confirming ownership of the email domains being used within Dynamics 365, ensuring that email communication operates smoothly and is less vulnerable to phishing attacks or other security threats.

Email domain verification ensures that emails sent from the Dynamics 365 system are recognized as authentic by recipients' email servers, which helps reduce the likelihood of emails being marked as spam. Additionally, this verification is a prerequisite for features such as server-side synchronization, which allows Dynamics 365 to sync emails, appointments, contacts, and tasks seamlessly with users' email accounts.

Other choices, while related to the broader context of using Dynamics 365, do not specifically address the requirement for mailbox configuration. Integration with LinkedIn, for instance, is useful for leveraging networking tools but is not fundamental to setting up mailboxes. A subscription to Microsoft 365 is a general requirement for many features within Dynamics 365 but does not specifically relate to the mailbox configuration process. Lastly, user authentication is an important aspect of security but does not encompass the verification of the email domains that is essential for mailbox configuration.
