2.1.2. Outlook offline storage engine
The Zarafa client was updated to contain the latest MySQL embedded edition for offline usage. The new storage engine was replacing the older version which removes a number of smaller internal storage issues for larger offline profiles, some older Unicode issues and provides performance improvements.
Offline users must expect an upgrade of their profile when starting Outlook the first time after the installation of the new Zarafa client. The upgrade time will take from 10 minutes to 2 hours depending on the size of the offline data profile and the PC performance. During the upgrade the user can work online with the Zarafa Server to continue the work.
The upgrade process may be interrupted by sleep mode or hibernation and will continue then at the next start. Offline mode is not available until the upgrade is completely finished.
