Recurrence trigger missed – A scheduled recurrence trigger did not fire at the expected time.

Power Automate’s Recurrence trigger is used to schedule flows at specific intervals (e.g., every hour, daily, weekly). However, users may sometimes experience the following issue:

“Recurrence trigger missed – A scheduled recurrence trigger did not fire at the expected time.”

This issue occurs when the scheduled trigger fails to execute at the defined time, causing delays or missing executions entirely.

2. Causes of the “Recurrence Trigger Missed” Issue

Several factors can prevent the recurrence trigger from firing as expected:

Flow Turned Off or Suspended – If the flow is disabled or has been suspended due to usage limits, the trigger will not execute.
Concurrency or Parallelism Conflicts – If another instance of the flow is still running when the recurrence trigger is scheduled, it may be skipped.
Power Automate Plan Limitations – Free and lower-tier plans have execution frequency limits, which might restrict how often a recurrence trigger can fire.
Service Downtime or Latency – Microsoft services might be experiencing delays, causing the trigger to be missed.
Time Zone or Daylight Saving Time Issues – The recurrence schedule may be misaligned due to incorrect time zone settings.
High Server Load or Execution Queueing – Power Automate may delay executions during peak usage periods.
Incorrect Start Time Configuration – If the recurrence trigger is set to start at an incorrect time, it may not fire as expected.
Environment Throttling – If too many flows are running simultaneously in an environment, the recurrence trigger may be deprioritized.
Flow Errors in Previous Runs – If the flow failed in a previous run, Power Automate may pause execution until the issue is resolved.

3. Step-by-Step Troubleshooting Guide

Step 1: Check Flow Run History

Open Power Automate (https://flow.microsoft.com).
Navigate to My Flows and find the affected flow.
Click Run History to see past executions.
If the flow did not run at the expected time, check if there are error messages or skipped runs.

Step 2: Ensure the Flow is Enabled

If the flow is turned off, turn it back on.
If the flow is suspended, check for error messages indicating why it was paused.

Step 3: Verify Recurrence Settings

Open the flow and locate the Recurrence trigger.
Expand the Settings and check:
- Frequency (Seconds, Minutes, Hours, Days, etc.)
- Interval (How often the trigger fires)
- Time Zone (Ensure it matches your local time)
- Start Time (Ensure it is correctly set)

Example of a correctly configured Recurrence trigger:

Frequency: Hourly  
Interval: 1  
Start Time: 2025-03-10T08:00:00Z (UTC format)  
Time Zone: Pacific Standard Time

Step 4: Adjust Concurrency Settings

If multiple instances of the flow could be running at the same time, Power Automate may skip a recurrence trigger to avoid conflicts.
To fix this:
1. Open the Recurrence trigger settings.
2. Enable Concurrency Control and set it to 1 to prevent conflicts.

Step 5: Check Power Automate Plan and Limits

Power Automate Free & Standard Plans:
- The free plan allows a maximum of one flow execution every 15 minutes.
- Standard plans may have similar restrictions based on licensing.
Power Automate Premium or Per-Flow Plans:
- Can run flows as frequently as every 1 minute.
To check limits:
- Go to Power Automate > Settings > Billing & Licensing.
- If necessary, upgrade to a plan that supports higher frequency execution.

Step 6: Review Microsoft 365 Service Status

If Power Automate services are experiencing delays or outages, scheduled flows may not trigger.
Check Microsoft’s status page: https://status.office.com.

Step 7: Align Time Zone and Daylight Saving Adjustments

Power Automate operates in UTC by default.
If a flow is missing triggers due to daylight saving changes, adjust the Time Zone setting in the Recurrence trigger.
Convert local time to UTC to ensure correct scheduling.

Convert Local Time to UTC Example:

Pacific Time (PST): 6:00 AM → UTC: 14:00 (2:00 PM)
Eastern Time (EST): 6:00 AM → UTC: 11:00 AM

Step 8: Avoid High Server Load and Throttling

If many flows are running in your environment, some may be delayed or deprioritized.
To optimize performance:
- Reduce unnecessary flow runs.
- Use batch processing instead of frequent recurrence.
- Stagger flow execution times to avoid simultaneous triggers.

Step 9: Recreate the Recurrence Trigger

If the issue persists, delete and re-add the Recurrence trigger.
Reconfigure the settings and test the flow.

Step 10: Use an Alternative Trigger

If the recurrence trigger continues to miss executions, consider:

Using an Instant Trigger – Manually start the flow when needed.
Using a Scheduled Cloud Flow – Instead of a recurrence trigger, set up a scheduled execution.
Using Power Automate Desktop – For high-frequency automation, use desktop-based scheduling.

4. Preventative Measures

To avoid recurrence trigger failures in the future:

✔ Monitor Flow Execution History – Regularly check for missed executions.
✔ Optimize Trigger Frequency – Avoid excessive execution intervals.
✔ Use Correct Time Zone Settings – Prevent daylight saving time misalignment.
✔ Upgrade Plan if Necessary – Ensure you have enough flow runs per day.
✔ Spread Out Scheduled Flows – Avoid concurrent executions.
✔ Enable Notifications for Failures – Set up alerts for missed runs.
