I've been doing tests with Kopano to evaluate if there is a way to keep using Zarafa (now Kopano) even after the support for the Outlook client has ended.
Doing so I've noticed that when using Kopano 8.1 / 8.2 with the Zarafa Windows Outlook Client (7.2.4-52167), suddenly in Outlook 2010 calendar reminders (notifications) pop up for shared calendars (such as calendars in the public folder).
I'm 100% sure that this was not the normal behavior in Zarafa 7.1 and I'm reasonably sure this also was not the behavior with Zarafa 7.2.
Is this a deliberate change? Can this be turned off somehow? It's kind of annoying.
