Lost my Notes after I deleted my exchange account

Hi,

I had several Notes stored locally (no backup taken) which was configured with my previous employer email id. Last night, fed up with constant reminders of meetings, I tried deleting the account setup in my Calendar. In process it asked me to delete account from exchange. Which I did not knowing what havoc it will do to my Notes.

Today when I opened my Notes app, I was greeted with blank screen. All my Notes gone.

I tried to recover from the NotesV7.storedata file but no use. Is there any way I can recover my Notes.

Thanks

Ashish
