It is a software interface that enables any MAPI client to communicate withany mailserver (MS Outlook and Kerio MailServer in this case).To enable traffic via the MAPI interface, Kerio Technologies developed Kerio Outlook Connector,a special application which is installed on a client and work as an MS Outlookextension. MS Outlook extended by Kerio Outlook Connector handles email in the samemanner as the IMAP protocol, and it even allows additional options.Thanks to this modification, MS Outlook is able to work with groupware data (contacts,calendar, tasks, notices) stored in Kerio MailServer. The main benefit of the shared datastore is that the data is available via the Internet anywhere necessary. To access the data,you’ll need just an Internet connection and a web browser (the Kerio WebMail interface),MS Outlook with the Kerio Outlook Connector.MS Outlook with the Kerio Outlook Connector also enables better scheduling of meetingsand tasks (the Free/Busy calendar) as well as sharing of various types of data (shared andpublic folders).For more information on Kerio Outlook Connector, see chapter 32.2.Access via the WebDAV interface (MS Entourage)Kerio MailServer supports the WebDAV interface (Web Distribution Authoring and Versioning)which can also be used for accessing email accounts.
