Thank you for a great utility!
I'm running Outlook 2010 under Windows 7 and every so often my MCL disappears. A week or so ago I downloaded your Export & Import MCL utilities and immediately Exported the list and yesterday, after my MCL went away again, I successfully restored it using Import.
I haven't been able to determine the trigger that's causing the list to go away, but I've recently bought an Android phone and have installed some programs that "touch" Outlook, although I have them all set to sync in the outbound direction only, never writing to Outlook. I'm now using Google Calendar Sync and MilkSync and probably other Google-related programs.
Thanks again - I'm definitely going to donate some money for your excellent utilities.
