Hello ,

I just install the Zimbra Desktop program, synchronised all my emails from Exchange through IMAP but did not find a way to synchronise my Exchange Calendar (related to my email).

I tried to use the "Synchronize appointments from remote calendar" option with :
but i got this error message :
Appointments could not be retrieved. Make sure the following URL is a valid ICAL feed: https://ExchangeIP/Exchange/

Is it possible to synchronise Zimbra Desktop with Exchange Calendars (by any way)?
If yes, did I use the right way? If so, how could I succeed? If not what is the right way?

Tanks a lot for any of your answers or advices .
