Will Power Automate Notifications Trigger Persistent Outlook 2019 Failures?
Reports indicate that emails generated by Microsoft Power Automate flows can trigger immediate crashes in Outlook 2019 clients, even when all add-ins are disabled and the application is run in safe mode. This issue appears on multiple, fully updated systems—including fresh Windows 11 installations—suggesting a broader compatibility or formatting conflict rather than isolated corruption or user error.
Observed Symptoms
Outlook 2019 crashes as soon as a Power Automate-generated email is previewed or opened. The issue persists across several devices and user profiles, ruling out local corruption.
Disabling add-ins and running in safe mode does not prevent the crash. Event logs only show generic AppCrash entries, offering little diagnostic detail.
Known Troubleshooting Steps (with Limited Success)
- Deactivating all add-ins (no effect).
- Running Outlook in safe mode (no effect).
- Repairing Office installation and Outlook profiles (no effect).
- Rolling back recent Office updates (no effect in some cases).
- Checking for updates and ensuring latest patches are installed.
Potential Root Causes
- Specific formatting or content in Power Automate emails may be incompatible with Outlook 2019’s rendering engine.
- Loops or misconfigurations in Power Automate flows can exacerbate the issue, as noted in similar forum reports.
- Recent Office updates might have introduced new bugs affecting email parsing or previewing.
Recommended Actions
Solution 1: Test with Different Email Formats
Adjust Power Automate flows to send plain text instead of HTML or vice versa to identify if formatting is a trigger.
Solution 2: Check for Known Office Bugs
Monitor Microsoft’s official channels for any hotfixes or temporary workarounds, as similar issues have been patched in the past.
Solution 3: Use Diagnostic Tools
Run the Outlook advanced diagnostic troubleshooter or Microsoft Support and Recovery Assistant for deeper analysis.
Solution 4: Isolate Problematic Flows
Disable or modify Power Automate flows suspected of causing the crash and test Outlook’s stability after each change.
Solution 5: Engage Microsoft Support
If the issue persists and impacts business operations, escalate to Microsoft with detailed logs and sample emails for analysis.
