BundleValidationError - Microsoft 365 Email (Outlook)

:bullseye: What is your goal?

I’m trying to fix a Make.com integration between Outlook (Microsoft 365 Email) and Microsoft 365 Calendar that should automatically create a calendar event based on email activity.

:thinking: What is the problem & what have you tried?

I’m trying to fix an integration that was built for me in Make.com between Outlook (Microsoft 365 Email) and Microsoft 365 Calendar.

Scenario flow:

Microsoft 365 Email (Outlook): Delete an Email
Microsoft 365 Calendar: Create an Event

When I run the scenario, I get the following error:

“The operation failed with an error. Validation failed for 2 parameter(s).”

The scenario initializes successfully, but fails during execution.

I’ve already tried many times to fix the integration myself:

I verified and updated the email address configuration across all modules
I checked the Outlook and Calendar connections
I reviewed the field mappings multiple times
I retried the scenario several times after making adjustments

Unfortunately, I still can’t identify which parameters are failing validation or what exactly is causing the issue.

I’d appreciate help understanding:

Which two parameters are failing validation
Whether required fields are missing or incorrectly mapped
How to properly debug this type of validation error in Make.com

:clipboard: Error messages or input/output bundles

The operation failed with an error.
Validation failed for 2 parameter(s).
