  • SleepMe-Console.EXE

    - Shows console messages while trying to put the computer to sleep. Use to debug why the "SleepMe-Hidden" program may not be working... You will need to run once as Administrator as it disables the Windows "Hibernate" feature so the sleep command doesn't go to sleep too deeply.

  • Outlook IMAP Deletion Issues:

    It's good that Outlook does not forever delete messages immediately in IMAP accounts. That allows for easy undeletion. It also allows for messages to accumulate, however, and for folders to grow bigger and bigger — until you purge deleted items. Now, you can do that on your own from time to time (once a week should be enough). Or you let Outlook do it automatically.
    Automatic Purging's Dangers
    Y
    ou do lose a bit of the safety net, though: there's no guarantee that a message will be recoverable for a certain time. Whenever you change folders, all the deleted items in the folder you left have just been purged.
    Purge Deleted Messages Automatically in Outlook (2007 + later)
    To have Outlook purge messages marked for deletion automatically when you leave a folder:
        + Select or Open a folder in the IMAP email account you want to setup for automatic purging
        + Select Edit | Purge | Purge Options... from the Outlook menu
        +Make sure Purge items when switching folders while online is checked
        + Click OK
