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.
