Hi everyone,
I have a tricky situation. I am able to add  contacts as event invitees through apex code but an email is not being sent . On the Event record, the contact names are being populated in the " Has'nt Responded " section of the related list. Only if the contact accepts the invitation, his name would come up in the " Accepted " section of the related list . Untill and unless contact gets an email, he/she cannot accept the invitation.

Any help is appreciated. Thanks in advance.
