Microsoft Exchange Online - Update a calendar item

What it does

This action transforms, extracts, or stores data used by later workflow steps. The converted flow must preserve the source expression, output variable, and any formatting or type conversion behavior.

How Flow Migrator maps it

Flow Migrator maps this to Outlook authenticated Graph PATCH event + typed response using Office 365 Outlook / Microsoft Graph. Uses the native Outlook authenticated Microsoft Graph request for the signed-in mailbox. Preserves the original event ID, explicit payload, typed response and complete list pagination. Confirm the mailbox, event IDs, time zones and tenant permissions before activation. Unsupported source parameters remain blocked. Flow Migrator has a direct or proven best-effort conversion path for this mapping.

Common migration issues

• Validate SharePoint site, list/library, content type, required fields, person fields, lookup fields, and attachment or file path behavior.
• Run a test instance and compare outputs against the original Nintex workflow before production migration.

Validation checklist

1. Open the generated flow and confirm the action card imported correctly.
2. Validate connection references and required settings before running the flow.
3. Test with representative source data from the original workflow.
