Dynamic, Multiple Recipients of D365 Email in Power Automate

When the activity parties (TO, From, CC) ae static, we can easily send emails. However here is how we can set the activity party dynamically on the Email.

 

 In above screenshot we can see the Activity party attribute is populated for single value and is static to only a single entity record GUID.

 

Solution:

The create a record of Email message is as below, here we are entering the attributes of activity party, by clicking on "Switch to Input entire array"

You will get the Array format, the participationtypemask is TO, FROM,CC while the partyid@data.bind is the email address.

Now all you need to do is create a dynamic array, You can use append to array variable action to create an array with participationtypemask as per your requirement.

Example: get all users whom you need to send email, append the user id to array.

pass this array as input to the Activity Parties field in create an email record.
