Overview

Kerio Connect Archiving feature uses compressed ZIP archives to store the data. Once the data is stored, it appears in Webmail or Kerio Connect Client archive folders. If the folders are not visible, the users won't be able to access historical mailbox items. 

The archived emails can be restored manually using standard decompression functionality, then copying files and re-indexing the necessary user mailbox. The restoring from Archives can be used if there is a no backup mechanism in place or it was disabled for a certain period of time.

Diagnosis

Depending on Archiving interval settings, the appropriate archiving subfolders are created on a daily, weekly, or monthly basis.

The standard folder structure for Monthly Archive is the following:

Kerio Connect is not re-indexing Archive folders, and it is unable to recognize a folder that does not have status.fld file in it.

Solution

1. Create a new user with any name and assign Archive Folder rights.
   

   Note: You can use an existing user, but the new user will reduce re-indexing time that will be required later.

2. From the newly created user's webmail, create a new folder for Archive, for example, 2019-Dec, 2020-Oct, etc.
   

3. From the server-side, open the old 2019-Dec folder containing the archived emails and navigate to the #msgs subfolder. Copy all the .eml files from the #msgs subfolder.

   The directory structure of 2019-Dec will be similar:

   

4. Navigate to the new folder 2019-Dec, open the #msgs subfolder located in the user directory from step 1 and paste all the .eml files from step 3 to the #msgs subfolder. The default location for different OS would be:

   1. Windows: C:\Program Files\Kerio\MailServer\Store\Mail\[domain]\[username]\2019-Dec
   2. Linux: /opt/kerio/mailserver/store/mail/[domain]/[username]/2019-Dec
   3. Mac: /usr/local/kerio/mailserver/store/mail/[domain]/[username]/2019-Dec

5. Re-index the mailbox of the newly created user from step 1.

6. Check if the emails from the old Archive are visible in a new folder in the user webmail.

7. Stop the Kerio Connect server.

8. Move the 2019-Dec folder from the user directory to the Archive directory. The default location would be \MailServer\store\archive.

9. Start the Kerio Connect server.

Testing

The new folder 2019-Dec is visible under Archive Folders.
