This problem wasted 2 weeks of our life. So I hope this helps.
The error for Live Mail started when I upgraded ASUS Win7 laptop HDD from 640GB SATA2 to 1TB SATA3.
Tried to fix it by going through all steps found in different forums (eg. rename or deleting 'Calender' folder etc.), nothing helped except this:
1. Power up, press <F2> for BIOS settings
1. My BIOS setting for SATA was AHCI by default
2. I changed it to IDE, save and exit
Windows then find all the IDE drivers again. After that, Live Mail ver 2009 works straight away, with no more error 0x8E5E0247. (You might want to try an upgrade to a new BIOS version for your specific laptop model if above does not work for you - from
your laptop manufacturer website)
Good luck.
