Managing attendees in an Outlook event

Hi everyone,

I have a simple workflow aiming to add new attendees to an event.
Here’s how it works:

  • Watch Microsoft 365 events by updated time
  • Search rows in a Google Sheet
  • Update event with attendees found in the Google Sheets.

It works if the workflow runs only once. On the second time, it will keep the new attendee, but removes the original one. No change has been done to the event outside of Make.com. See screenshots below:

First run
Berlioz App as event host, Demo Example as original attendee. The workflow adds Ariane B. as new attendee. Everything works fine.
NB: After the workflow, Berlioz App is added as an attendee whereas it was the host, but it’s no problem for me.

Second run
Make.com lists the attendees fine in the first module, but inexplicably removes Demo Example during the last module.

Any help ? Thanks !

Hi everyone,

If anyone meets the same issue: i could not solve it and had to find a workaround.

Here’s how I process: I include the names of attendees in the event body (not with make.com), then I have make.com to copy the event body content on a gSheet. From there, I extract the names of the attendees with a formula in new fields. Then I have Make.com adding these fields as attendees.
