Re: Long Term Subscriptions to Events via WebDAV |
|
|
Hello,
the when using the WebDAV subscriptions, your subscription will time out
eventually. But you can renew your subscription by sending a custom WebDAV
command. So you can use a timer and renew your subscription every few
minutes or so (See http://www.infinitec.de/exchange/howtos/webdavevents.aspx
for an example).
Your other option is to register an event sink directly on the Exchange
server
(http://msdn.microsoft.com/library/en-us/e2k3/e2k3/_exch2k_iexstoresyncevents_interface.asp).

I would like catch an event each item a specific task/calendar item is
modified or deleted. I have looked at the WebDAV Subscription method
but I've have read elsewhere that there is a maximum subscription
length of around ~3600 seconds. I am looking for notification of
upwards to a year.
Is there another API I should consider looking at? Or, is it even
recommended to rely on Exchange to monitor for changes for so long?
Thanks,
Jelling
