  • Hi Srikanth,


    place the activity party in an array and then assign the array to the bccMember.

  • Hi Thanks for quick response I followed the below link to create email activity in plug-in while adding the contacts(more than one) to the "To" party lookup field, how we can add multiple contacts to the party lookup filed.

  • The most likely cause of your problem is if you either use the same Entity instance in your code to create more than one activityparty, or if you use an Entity instance for an activityparty to create a new activityparty. In either case, the primary key of the activtiyparty (activitypartyid) will not change, and that will produce the error. To prevent this, either create a new Entity instance each time, or remove activtiypartyid attribute, and set the .Id property to Guid.Empty to remove the reference to the existing primary key
