User manual KERIO TECHNOLOGIES OUTLOOK CONNECTOR

[. . . ] Simple attachment-free messages can make the proportion of user's and supportive data fifty-fifty, so that the local database would be double-sized in comparison with the data saved on the server. However, attachments need less space in the local database than they do on the server, because they are saved in their native format, while in the case of . eml files on the server the Base64 encoding is used (with the 3:4 ratio). The local database file is not always larger than its mirror on the server. This could be the case if a user does not synchronize the full message bodies in some folders (i. e. [. . . ] If Kerio Connect 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 OK. Here is the path to the configuration dialog: Start Settings Control Panel Mail Properties <profile_name> E-mail Accounts Change <account_name>. If multiple users work on the same computer, users who did not install KOFF themselves must convert their profile by running the conversion manually: Start Programs Kerio Outlook Profile Conversion Utility. 3 Conversion of KOC profiles to KOFF profiles does not affect accounts of other types (IMAP, POP3, etc. ). 3. 5 Global installation by using Active Directory 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. 4 Initial synchronization Initial synchronization is a process started upon the first logon to a new profile in Outlook extended by KOFF. Within the process, data is copied from the server to the user's computer thus creating the KOFF's local database. 4. 1 How the initial configuration works To make managing of email accounts in offline mode (without connection to the server) possible, all user data (email messages, contacts, events, tasks and notes) must be stored in a local database on the client's system. Synchronization of the local database with the server runs in the background without user's interaction. Instead of PST files, KOFF uses a proprietary built-in database (Firebird, version 2). 4. 2 Default synchronization settings The default configuration of the initial synchronization is as follows: · The Inbox folder is fully synchronized (i. e. complete email messages including · In other email folders, only message headers are involved in the synchronization. · Encrypted and digitally signed messages are always fully synchronized. · Other folders (contacts, calendar, tasks and notes folders) are always fully synchronized. Let us focus on the issue of how to set full synchronization of all folders. Right-click on the root folder (Mailbox of. . . ) and select Folder properties. . . / Folder synchronization / Synchronize whole messages and then Apply these settings to all subfolders. 4. 3 Impact on the server's and client's performance Initial synchronization is very demanding with respect to system resources of both the client and the server. Speed and total time of initial synchronization depends on several factors: · Load on the server depends above all on number of clients being synchronized at the particular moment. The hard disk performance is the main limiting factor on 4 the server's side. For example, when performing tests on a PC (Pentium 4, 2. 4 GHz, 1 GB RAM, 7200 RPM HDD), during a synchronization of several clients at once, the measured data transfer speed in the server-to-client direction was approximately 120 MB per minute. [. . . ] 5. 3 Downgrade to KOC In case of serious problems with KOFF, it is possible to downgrade to KOC again quite smoothly. Although KOC is removed within KOFF installation, both extensions can be installed on the same computer without any collisions. After KOC reinstallation, it is necessary to create a new profile since the original one has been converted for KOFF. 5. 4 Logging of important information KOFF also brings new options of more detailed logging of communication in files on the server.
