You need to design a Power Automate flow that sends a welcome email to a new user immediately after their account is created in Microsoft Entra ID. Which trigger should you use?
Answer choices
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
✓
When a user is added
'When a user is added' triggers when a new user is created. Option A is wrong because it triggers when a user is deleted, not created. Option B is wrong because it triggers when a group is added, not a user. Option C is wrong because it triggers when a user is updated, not created.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
When a user is removed
Why it's wrong here
Removal triggers fire on account deletion, so no welcome email could ever be sent to a new user; the event never matches. This trigger is correct for offboarding flows, such as revoking licences or archiving mailboxes when someone leaves.
- ✗
When a group is added
Why it's wrong here
Group membership changes concern group objects, not user account creation, so creating a user without adding them to a group fires nothing. This trigger suits flows that react to security group or Microsoft 365 group membership changes, such as granting shared mailbox access.
- ✗
When a user is updated
Why it's wrong here
Update triggers fire on modifications to an existing user, so the initial creation event is missed entirely; the welcome email would only send on a later edit. This trigger is correct for synchronising profile changes, such as department or job title updates.
- ✓
When a user is added
Why this is correct
The 'When a user is added' trigger fires on Microsoft Entra ID user-creation events, satisfying the requirement to send the welcome email immediately after account creation. It is the native Entra ID connector trigger designed for this event.
