After being pestered about upgrading from Windows 7 to Windows 10, I finally complied. I hated it. So I restored my Windows 7 this morning. When I opened my email and checked my defaults email account, I found I lost everything in my inbox and sent folders. I am an executor of an estate and kept all the important communications in my inbox and sent folders so I could access it quickly if needed. Now it's all gone. Can anyone tell me how to recover it?
