Windows Live Mail on Windows 10(64 bit)

WLM won't start when I move the message store to D: drive. It says my calendar contains corrupt data. Codes 0x8007057 & 0x8E5E0408.  Uninstall and reinstall was no help. If I delete the registry keys under CURRENT USER... WLM, it will start again, but the store is back to C: drive. Which is a rather small SSD, and naturedly the System drive. That is the reason that I'm trying to get the emails on D: drive. I've deleted the Calendar folder, and the DB subfolder to no avail. Each time that I move the message store to D: drive, WLM fails to start. I store my emails locally, and don't use Outlook.com
