hoagieryder Help with iCal Meeting Request Update
I am trying to develop an e-mail that is sent to request a meeting date that updates the user's e-mail calendar using an ical file. I have everything working perfectly, except when I try to modify a previous request. For instance if I send a request for a meeting on Sept 12th, and the meeting date changes I would like for it to be moved on the user's calendar, not for a new appointment to be added. I have been messing around with sequences and nothing has helped. I am opening these e-mail through Groupwise not Outlook. Any ideas?
First Meeting Request:
public class SendEmail{
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 = 'quarter1meeting.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';
txtInvite += 'PRODID:-//Microsoft Corporation//Outlook 12.0 MIMEDIR//EN\n';
txtInvite += 'VERSION:2.0\n';
txtInvite += 'METHOD:REQUEST\n';
txtInvite += 'X-MS-OLK-FORCEINSPECTOROPEN:TRUE\n';
txtInvite += 'BEGIN:VEVENT\n';
txtInvite += 'CLASS:PUBLIC\n';

txtInvite += 'LOCATION:Online\n';
txtInvite += 'PRIORITY:5\n';
txtInvite += 'SUMMARY;';
txtInvite += 'LANGUAGE=en-us:Salesforce Test\n';
txtInvite += 'TRANSP:OPAQUE\n';
txtInvite += 'X-ALT-DESC;FMTTYPE=text/html:<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 3.2//EN"><HTML><HEAD><META NAME="Generator" CONTENT="MS Exchange Server version 08.00.0681.000"><TITLE></TITLE></HEAD><BODY><!-- Converted from text/plain format --></BODY></HTML>\n';
txtInvite += 'X-MICROSOFT-CDO-BUSYSTATUS:BUSY\n';
txtInvite += 'X-MICROSOFT-CDO-IMPORTANCE:1\n';
txtInvite += 'END:VEVENT\n';
txtInvite += 'END:VCALENDAR';
return Blob.valueOf(txtInvite);
}
}
