Implement support for MAPI with help from [[ http://www.openchange.org/ | OpenChange ]] to allow native Outlook clients to connect to Kolab and all groupware data.
**Rationale:**
Unfortunately, Outlook is still the major groupware desktop client. For many companies flawless Outlook support is a hard requirement for their groupware solution. There are many connectors for Outlook that allow it to interface with Kolab. These however are of varying quality and incur additional costs, so that a native and direct Outlook connection is preferred by all stakeholders.
