Yesterday I received a message that my email crashed on my Thunderbolt, and now the Mail client won't work. When I open it my email is not longer there and the menu of options is not the same as all of the online help that I've looked through says it will be. My phone still says that all of my emails accounts are there, but I am not able to see them in the mail client. Has this happened to anyone else? What can be done to fix it?
