Hi all,

I've been using Zimbra - in combination with Outlook connector - for a long time. Last week, I had to add another mail account in Outlook, this time an Exchange account.
For some reason, Outlook has decided the new account's calendar should be the default Outlook calendar. As a result, I can't see my pending appointments (from my Zimbra calendar) in the Outlook taskbar any longer, really annoying.
When I close Outlook and try to set the Zimbra calendar as the default calendar through Configuration items > Mail > Data files it complains something about PST and OST files and switching off caching in the account settings and doesn't want to change it.
I have no idea where to start looking, any ideas?
