How to update automatically the organizer’s calendar?

Asked By 0 points N/A Posted on -

I am using a PHP application that can generate .ics files and then send these files as attachments to the users within the organization. Once the attendee receives and opens this attachment, an entry is added to his calendar and then he is asked if he wants to accept or reject the entry. The system has been working well for some time, however, the organizer’s calendar does not update automatically. At times, an attendee receives an attachment such as “As an organizer, you do not need to accept this meeting” but the entry would not be reflected in his calendar.

I already tried adding organizer to the attendee but it did not work. My questions are :

1) How do I add an entry in the organizer’s calendar, so that an attendee will find it once he opens the .ics attachment, and

2) Why does not Microsoft Outlook recognize the command METHOD: CANCEL whenever I try cancelling the receipt of an .ics attachment?

I am hoping that you will be able to help me find a solution. Thank you.

Hallo Emmanuel E,

The reason why the recipient is able to receive the attachment by they cannot be able to view the message in the calendar is because the attachment may be blocked against being accessed by an outlook security feature which guards against your computer being exposed to viruses and other malware that may be embedded in the attachments are send in mails. But you can send the attachment in a manner that will enable the recipient will be able to view it.

One method that you can send the attachment so that the recipient will be able to read it is by first zipping the attachment. The compressed format protects the attachments from any attack by viruses, and some programs that will help you compress the attachment are WinZip and WinRar which you can download for free online.
