Overview

Kerio Outlook Connector, so-called KOFF, can synchronize any folder with the Kerio Connect server in the Online (default) or Offline modes.

Mode	Description
Online Mode	It is the standard MS Outlook mode which requires a connection to Kerio Connect.
Offline Mode	It allows working with MS Outlook without connection to Kerio Connect. This requires all emails, events, tasks, etc. are stored in the local message store on the client station. When you switch to online mode, all new messages, events, and tasks are synchronized with the server's store automatically. Note: once you set the offline mode, the online mode should be switched on manually.

For the folder synchronization, it supports full whole messages synchronization and synchronization of header and message body in plain text — with this option, attachments are not downloaded automatically.

The default synchronization works as follows:

• Inbox — Whole messages are synchronized.
• Other email folders — Only message headers and body in plain text are synchronized.
• Events — Whole events are synchronized.
• Contacts — Whole contacts are synchronized.
• Tasks — Whole tasks are synchronized.
• Notes — Whole notes are synchronized.

Upon each startup of Microsoft Outlook, Kerio Outlook Connector synchronizes the currently opened folder first. 

Solution 

Setting Folder Synchronization

To enable/disable synchronization and select a synchronization mode of individual folders, follow these steps:

1. Right-click a folder and select Properties.
2. In Folder Synchronization, select the synchronization mode (enable/disable).
   
   Optionally, enable "Set also to all subfolders now" if you have nested subfolders presented.
3. Confirm the settings by clicking OK.

Note: If you disable synchronization of a previously synchronized folder, all present items will remain synchronized.

Solving synchronization conflicts

A synchronization conflict occurs when a message, event, or any other item is changed both on the server and in Kerio Outlook Connector between synchronization.

If a conflict occurs during the synchronization:

1. The item saved on the server overrules the item in Microsoft Outlook (Kerio Outlook Connector).
2. You receive a special message with information about the conflict.
3. The item from Microsoft Outlook is saved in a special folder called Conflicts (available only in MS Outlook).
4. If you prefer to keep the item in MS Outlook, move it from the Conflicts folder and replace the synchronized item from the server to the original folder.
5. Reindex the mailbox as explained in the Fixing Data Consistency Issues
6. If the above steps did not resolve the issue follow the steps to Reset the User profile from Server
