Microsoft Outlook (2026-11-13)

Added an option to skip the message fetch on the Mail Message Webhook trigger, and updated existing actions and triggers:

  • Added the Skip Message Fetch input to the Mail Message Webhook trigger, so the trigger can respond to Microsoft Graph without fetching each message and fewer notifications are retried; notifications then carry no messageData
  • Updated the Delete Calendar, Delete Event, Cancel Event, Delete Mail Folder, Delete Message, and Delete Subscription actions to return a result with success, id, and message instead of an empty response
  • Added output schemas to 7 actions for improved field mapping during configuration
  • Updated the Update Event action to group its Location Name, Subject, and Body (HTML) inputs into an Event Details structured object
  • Updated Update Event to accept an empty Attendees value instead of rejecting it
  • Updated Get Schedule Availability to leave the interval out of the request when Availability View Interval is empty, instead of sending 0
  • Updated Send Message to trim the addresses in To, CC, and BCC and drop the empty entries that extra commas leave, and to fail with a clear error before sending when To holds no address
  • Updated the Calendar Event Webhook and Mail Message Webhook triggers to skip the message or event fetch for a notification that carries no resource ID, instead of reading the whole collection
