Power Automate Trigger Conditions: Troubleshooting Missing Emails
You have a Power Automate flow that sends an email notification when a new file is added to a SharePoint document library. Users report that emails are not being sent for some files. What is the most likely cause?
Quick Answer
The answer is a trigger condition filtering out some files. This is the most likely cause because Power Automate trigger conditions allow you to set expressions that must evaluate to true before a flow runs; when a new file is added to a SharePoint library, if the file doesn’t meet the condition—such as a specific metadata value, file extension, or size threshold—the flow simply won’t trigger, and no email is sent. On the PL-900 exam, this concept tests your understanding of how trigger conditions act as a gatekeeper, often appearing in scenario-based questions where flows work for some items but not others, with the common trap being to blame permissions or connection errors instead. A solid memory tip is to think of trigger conditions as a bouncer at a club: if the file doesn’t have the right “ID,” it doesn’t get in, and no email gets sent.
⚠ Common exam trap
Test-takers frequently assume email failures are due to licensing or content issues, but the most common cause in practice is a misconfigured trigger condition that silently filters out legitimate file additions.

Correct answer & explanation
✓
A trigger condition is filtering out some files
Trigger conditions in Power Automate allow you to define expressions that must evaluate to true for the flow to run. If a condition is configured to filter out certain files (e.g., based on file name, metadata, or size), those files will not trigger the flow, and no email will be sent. This is the most likely cause when emails are missing for some files but not all.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The flow uses a premium connector that requires a license
Why it's wrong here
Incorrect. SharePoint and email connectors are standard.
- ✗
The file is being co-authored by multiple users
Why it's wrong here
Incorrect. Coauthoring does not affect trigger.
- ✓
A trigger condition is filtering out some files
Why this is correct
Correct. Trigger conditions may exclude files based on metadata.
- ✗
The file content contains sensitive information
Why it's wrong here
Incorrect. Content does not block trigger.

Same concept, more angles
1 more way this is tested on PL-900
These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. You have a Power Automate flow that sends a notification to a Teams channel when a high-priority ticket is created in Dynamics 365. The flow works correctly for most tickets, but occasionally a ticket is missed. Upon checking the flow runs, you see that some runs show 'Skipped' status. What is the most likely cause?
medium- ✓ A.The trigger has a condition that filters out tickets with priority lower than 'High'.
- B.The flow requires a premium license, but some users have standard licenses.
- C.The flow's concurrency setting is too high, causing some triggers to be ignored.
- D.The flow uses a connection that has expired or lacks permissions.
Why A: The 'Skipped' status in Power Automate indicates that the flow was triggered but the trigger condition evaluated to false. In this scenario, the trigger has a condition that only allows high-priority tickets to proceed. When a ticket is created with a priority lower than 'High', the condition fails and the run is skipped. Option A correctly identifies this filter. Option B is incorrect because licensing issues would typically cause errors, not skips. Option C is wrong because high concurrency leads to queuing not skipping. Option D is incorrect as expired connections would cause failure, not skip.
