These instructions provide recommended guidance through deployment of KOFF (either migration from KOC or a new implementation of the extension) in a production environment.
The first essential thing to be done is installation or upgrade of Kerio MailServer to the recent version. This procedure is simple, intuitive and it is described thoroughly in the product's documentation so this part will be skipped in this document. However, it is important to not skip it in reality since KOFF does not support Kerio MailServer versions older than 6.5.0.
If a previous version of Kerio MailServer (6.4.x) and the KOC extension for Outlook have already been used in the production environment, it is strongly recommended to upgrade existing KOC components to the up-to-date Kerio MailServer version before installing KOFF. Upgrade to the latest version will be offered automatically upon upgrade of the server and startup of Outlook on client hosts.
KOFF installation is almost identical with installation of the previous generation extension. If this is the very first installation of the Outlook extension, a new Outlook profile must be created upon completion of this installation.
In case of migration from KOC to KOFF, the installation wizard first uninstalls KOC and then installs KOFF. In this case it is not necessary to create a new profile because the existing profile is converted automatically. Description of the conversion is provided in the following chapter.
The installation wizard converts all KOC profiles of the user currently logged on the host during the installation to the KOFF format. In case that Kerio MailServer is available, the conversion includes also the configuration of its account. Upon the next startup of the same Outlook profile, initial synchronization of messages with the local database is started.
If Kerio MailServer is not available during the conversion, the configuration of the account cannot be finished. To synchronize account settings with the server, open the dialog for the account configuration of the particular profile and finish the configuration by clicking on . Kerio MailServer must be available for this action . Here is the path to the configuration dialog: .
If multiple users work on the same computer, users who did not install KOFF themselves must convert their profile by running the conversion manually: .
Conversion of KOC profiles to KOFF profiles does not affect accounts of other types (IMAP, POP3, etc.).
It is also possible to install KOFF for all users directly from the Active Directory domain. However, this installation method is highly unrecommended in cases where there is the danger of mass synchronization of too many clients at one time (this might lead to the server's overload). This issue is focused later in this document.
