Environment

  • GFI MailArchiver 2014 or older
    Note: GFI Archiver 2015 or newer should not be affected by this situation anymore as the program detects and renames corrupt profile files automatically now.
  • All supported environments

Root Cause

This issue is due to a corrupt cookie file, which often appears as 0 bytes in size.

Resolution

  1. On the GFI MailArchiver server, navigate to:
    • 2012 and later: ..\GFI\MailArchiver\ASPNET\UI\Profiles
    • 2011 and earlier: ..\GFI\MailArchiver\ASPNET\Profiles
  2. Locate the user's cookie file which appears as 0 bytes in size and delete the file. It will be recreated with a clean version.

Confirmation

Try the search again.
