    Outlook doesn't work on Android with major ISPs email.  Used to, but stopped about 2 months ago.  Try to connect, get "your server certificate is invalid".  Many many forum entries. Microsoft are clearly just hoping the problem will go away.  Other Android email clients work fine (I have tried three.  I'm using the gmail app as a workround.)

    Hi guys. If you have a tiscali or talktalk account it may actually work now. Just tried it a few moments ago and it just started working. Even double checked to make sure it wasnt a troll but it is working finally
