Building Applications and Solutions with Microsoft 365 Core Services (legacy) — Question 11

You are developing a daemon application that reads all the emails in the inbox of a specific Microsoft 365 mailbox. Some emails contain meeting dates and room mailbox names.
The application has the following requirements:
✑ Move each processed email to a subfolder in the mailbox.
✑ If an email contains meeting data, create an event in the corresponding room mailbox calendar.
Which Microsoft Graph permissions should you grant for the application?

Answer options

• A. Calendars.ReadWrite and Mail.Read application permissions
• B. Calendars.ReadWrite.Shared and Mail.ReadWrite delegated permissions
• C. Calendars.ReadWrite and Mail.ReadWrite application permissions
• D. Calendars.ReadWrite and Mail.ReadWrite delegated permissions

Correct answer: C

Explanation

The correct answer is C because the application needs to have full access to read and write to both the calendar and mail, which is provided by application permissions. Option A lacks the Mail.ReadWrite permission needed for moving emails, while option B uses delegated permissions which are not suitable for a daemon application. Option D also uses delegated permissions, making it inappropriate for this scenario.
