ESA - filter calendar notifications

[tamaszoltan]

Hi,

Could someone help me how can I create filter to inbound calendar notification messages with the ESA?

Is it possible somehow?

Thanks,

Zoltan

in the past there was time where we needed to do this to overcome a software issue, so here our message filter used

CLIDetectCommonCalendarEntries5: if (header("X-MS-Exchange-Calendar-Originator-Id") OR (header("x-ms-exchange-calendar-series-instance-id")) OR (attachment-filename == "invite.ics") OR (attachment-filename == ".ics$")
OR (header("X-Barracuda-RBL-Trusted-Forwarder") OR (body-contains("BEGIN:VCALENDAR", 1)) {
drop();
}

Thank you! I'm going to test it.
