Modifying Storage Location for Kerio Outlook Connector (KOFF)

Author: Central Support Updated

Overview

This article covers the steps to change the location of the Kerio Outlook Connector Offline (KOFF) storage folder (directory) where the offline cache is stored.

There are two possible options to define where Kerio Outlook Connector Offline (KOFF) stores its internal cache (offline database). One option involves Windows registry modification (recommended way); the other option uses Microsoft tool Junction to redefine NTFS mount point.

The registry option is only available for version 7.2.0 and above.

Prerequisites

This article contains information about how to modify the registry. Make sure to back up the registry before modifying it and have a clear knowledge of how to restore the registry if a problem occurs. For more information about how to back up, restore, and modify the registry, refer to Microsoft's Knowledge Base article Windows registry information for advanced users.

 

Solution

Pointing KOFF Database Location to Use Custom Path:

  1. Open windows registry editor regedit.exe.

  2. Navigate to HKEY_CURRENT_USER\Software\Kerio\Outlook Connector (Offline Edition).

  3. Create a new String Value  REG_SZ (REG_EXPAND_SZ) and name it Cache Root Path.

  4. Add the requested path to the newly created String Value Cache Root Path.

    C:\Users\<username>\Desktop\koff_folder is the path being used in this example.

    KOFF will create the necessary directory structure in the specified folder.

Pointing KOFF Database Location to Use Roaming Profiles:

  1. Open windows registry editor regedit.exe and navigate to HKEY_CURRENT_USER\Software\Kerio\Outlook Connector (Offline Edition).

  2. Create a new DWORD (32-bit) VALUE REG_DWORD and name it Use Roaming Profile. Set the new registry key to a non-zero value. Then Roaming Profile Path should be configured as per MS manual. 

    NOTE: If both registry values are set, Cache Root Path has precedence.

    The specified path must be :

    • On local disks. No network drive (e.g., UNC Path) is allowed.

    • With read/write/create/delete permissions for the configured user account, it is recommended to set permissions with no access for other users to keep privacy.

    • Unprotected by UAC (User Access Control). This applies to Windows Vista and Windows 7 systems. The User Access Control is Microsoft's security technology, and its description can be found in Microsoft's Knowledge Base article Description of User Account Control. For Windows 10, more information on User Account Control can be found in the MS manual. 

Specifying Data Location Using Microsoft Junction Tool (Only for NTFS Filesystems):

The Microsoft Junction tool can be used to create symbolic links within the Windows NTFS file system. It can be downloaded from Microsoft's Junction page and includes information about symbolic links in greater detail.
