ics-Files

[Michael Bremer]

Hi All!

I've got a big problem reagarding *.ics-files. It's possible to create an
new entry in the calendar of my outlook. Receiving an *.ics-file with a
cancellation of this specific entry, Outlook creates an new entry instead of
deleting the old one.

Enclosed you find the content of an ics-sample.
I searched a lot in different FAQ and ask helping freaks, but no answer
which helped me with this problem.
In the RFC2445 is written, that the calendar should understand the command
ACTION with value CANCELLED to delete the entry. But outlook did not do.
Where is my mistake or is this not supported in the way I trie to?

Thanks a lot in advance!

Michael,
I have just been working on something similar. For your cancelled event you
need to specify the METHOD as CANCEL so for your example below you should
have something like what tou see below. Also your UID must match the UID of
the original event.
