I have been having a few problems with Windows Live Mail on Windows 7.
Once I installed Windows Essentials and loaded my Frontier Communications e-mail account, I was able to get emails, but could not reply, forward, or open to write a new email. A box would come up: "A problem occurred while trying to open this message. A problem occurred. Please try again."
Then, I was not able to open Windows Live Mail, as error 0x800C0155.2 came up. I am able to open Live Mail if I run it as the administrator. Not that big of a deal, but a bit of a pain.
Any ideas?
