Implementing a Hybrid and Secure Messaging Platform (legacy) — Question 24

You have a Microsoft Exchange Server 2019 hybrid deployment. The on-premises Exchange organization contains 500 mailboxes. The Exchange Online tenant contains 200 mailboxes.
You need to ensure that all users can use the Microsoft Outlook mobile app to access their mailbox.
What should you do first?

Answer options

• A. For each on-premises user, purchase a Microsoft Office 365 Enterprise E1 license.
• B. From Exchange Online, create a mobile device access policy.
• C. Add a TXT record to the public DNS zone of the Exchange organization.
• D. From the on-premises organization, create a mobile device access policy.

Correct answer: D

Explanation

The correct answer is D because creating a mobile device access policy in the on-premises organization is essential for controlling access for users on their mobile devices. Options A and B do not address the need for an on-premises policy, while C is unrelated to mobile access policies.
