I have succesfully installed and used a Zimbra Server on Linux and using it with Outlook clients on Windows. Everything works (calendar, contacts, mails and so on).
Now I am wondering if anyone knows about any issues with Zimbra installed on a Mac OS Server when using Windows Clients (Zimbra Desktop, Browser, Mozilla and so on). I believe there shouldn't be any problems with having windows clients and Mac OS servers, but just wondering if there are any issues before going on. Thanks in advance.
