Multiple calendars not syncing correctly with Outlook

[Okeanos]

Hello

I have multiple calendars within my zimbra account. Besides the default calendar I have one called "salesforce.com".

I sync with the latest Outlook Connector. The default calendar is synced perfectly. The additional "salesforce.com" calendar syncs irregularly.

If I ad a new entry to the "salesforce.com" calendar in Outlook it is synced to Zimbra correctly. But the other way around is not working. If an appointment is entered on the webclient it is not synced to Outlook (I use Outlook 2003, SP2).

Does anyone know why?

Best regards, Nick.
