Hi all.
I have the strangest problem with one user only. Calendar sync between Outlook ( and webmail, Samsung Android does not work.

Calendar sync works between Samsung Android and webmail AND between two computers running Outlook 2010 with connector but not between Outlook and webmail/Android. Just like hes ot two calendars running at the same account.

Outlook1<-->ZCS<-->Outlook2 OK!
Zimbra Webmail<-->ZCS<-->Android OK!

Zimbra Webmail<-->ZCS<-->Outlook NOT OK!
Android<-->ZCS<-->Outlook NOT OK!

Any ideas?

Cheers, Marcus
