hi, it depends on what you want to achieve. Open-Xchange meant to be a replacement of MSExchange just as OpenGroupware.org. Both were commercial products and later they opened the code. Both of them have outlook connectors (OX calls it OXtender). OpenXchange is a bit harder to integrate with Samba3 in PDC mode. But they can perform a very good job. You can buy commercial support also. Kolab also has an Outlook plugin to work seamlessly with Kolab but I didn't tested it. bye, Ago -- > Can any one recommend a decent groupware package that runs on Linux, > > I've looked at OpenExchange, and Kolab both of which look good, > > Regards > > Pete > > > > -- > This message has been scanned for viruses and > dangerous content by MailScanner, and is > believed to be clean. > > _______________________________________________ > CentOS mailing list > CentOS at centos.org > http://lists.centos.org/mailman/listinfo/centos >
