Send email to an email address which does not have calendar event



This is my first time asking for help on this forum so please let me know if you need anything else in my description


I have a calendar where my clients book in for meetings every two weeks.


I would like to create a flow where:

Trigger: Occurs every Monday at 1200pm

Action1: Gets all the events on my calendar from today to three weeks from now.

Action2: Gets the table data from an excel sheet(this is a list of emails to check for):

Action3: Compares the emails from the excel table and compares them against the events with an end result being an email sent to any emails that DO NOT have a calendar event. The purpose of this email is a reminder for them to book another meeting with me.


For example

















In this example, there is a calendar event for EmailAddressA and EmailAddressB but no calendar event for EmailAddressC so I want an email sent to emailaddressC to book into my calendar.


I understand how to do actions 1 and 2 but I am having trouble with making action 3 work.


Any help is greatly appreciated!

I would create an array of emails from the second list.  Then loop through those emails and see if each is in the first event list.  If not then add them to another blank array.  Once the looping is done that second array will have the list of addresses to send emails to.

I really appreciate the quick response.

I'm still learning the basics of how to put this stuff together. I understand what you are saying but I don't entirely know how to do that in power automate.

Would you be able to take a screen shot of what this would look like?

I've gotten as far as below but I don't know what to do next...
