You send alot of email using apex , but how do you send Calendar Invites? here in this post i will explain you how to send calender invites using apex
So to send meeting invites you need to follow the following steps :
1) first create a visualforce page on which put a button on click of which we will send metting invites.
2) Apex class that is used to send the email, and has a method that generates the Calendar invite.
so here is the visualforce page :
<apex:page controller="SendInvites">
<apex:form>
Email:
<apex:inputText value="{!sendTo}" />
<apex:commandButton value="Send" action="{!sendInvite}" />
</apex:form>
</apex:page>
Controller Class Code : SendInvites
public class SendInvites {
public String sendTo { get; set; }
public SendEmail() {}
public PageReference sendInvite() {
Messaging.SingleEmailMessage mail = new Messaging.SingleEmailMessage();
String[] toAddresses = new String[] {sendTo};
mail.setToAddresses(toAddresses);
mail.setSubject('Meeting Invitation');
mail.setPlainTextBody('');
Messaging.EmailFileAttachment attach = new Messaging.EmailFileAttachment();
attach.filename = 'meeting.ics';
attach.ContentType = 'text/calendar;';
attach.inline = true;
attach.body = invite();
mail.setFileAttachments(new Messaging.EmailFileAttachment[] {attach});
Messaging.SendEmailResult[] er = Messaging.sendEmail(new Messaging.Email[] {mail});
return null;
}
private Blob invite() {
String txtInvite = '';
txtInvite += 'BEGIN:VCALENDAR\n';
