Windows Live Mail database error (0x58000A)

I have found that Acronis will give this error (see attached) if WLM was signed into one of the online mail systems when closed, e.g. Gmail, Hotmail, etc.
I assume WLM stores a pointer to its current "Contacts" folder. Even though WLM is closed that pointer remains. My assumption is that Acronis uses this pointer and if it is not pointing at the local WLM pop3 folders it will fail.
So my solution is to sign out before closing WLM.

My system is Windows 8.1 with Windows live mail (Essentials) 12.
The Acronis version is Build 6673, Sync agent version 17,0,0,1877
