PL-900 Practice Question: Demonstrate the capabilities of Power Automate
A Power Automate flow that processes incoming emails and creates tasks in Microsoft To Do is not triggering for some emails. The flow uses the 'When a new email arrives' trigger with a filter on the subject containing 'Task'. What is the most likely reason some emails are missed?

Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The emails are older than 7 days.
The 'When a new email arrives' trigger in Power Automate only processes emails from the last 7 days by default. Older emails are ignored, so even if the subject contains 'Task', they won't trigger the flow. Option A is incorrect because the trigger can handle emails from external senders. Option B is incorrect because shared mailboxes work with proper configuration. Option C is incorrect because the subject filter applies to the entire subject line, not just the first word.
