Kerio Mail Server: Cannot access message 0000000x in folder

Submitted by Jochus on Thu, 21/02/2013 - 22:45 | Posted in: Windows


The following error appeared in the error.log of my Kerio Mail server:

Cannot access message 0000000x in folder ~<a href=""></a>/INBOX


In most of the cases, Kerio Mail Server is smart enough to repair the errors by itself. But in some cases, it just doesn't work. Manual repair is required.

  • Make sure all your clients are disconnected from the server - so you won't have any active sessions left
  • Go to the folder: /store/mail/domain/user/folder_name/
  • Rename the file index.fld to index.fld.bad
  • Now connect again with your user. Kerio Mail Server will see the index file is missing and it will automatically rebuild it. This step can take a while for very large mail folders!
