My i-Phone (4) has recently stopped 'Sending' e-mails.  It tries, but they remain 'Unsent' in the Outbox, and I get a message saying my 'Settings' are wrong, yet I don't recall changing anything.  Any advice, please, on how I might recover this situation?

Thanks.

I recently "upgraded" from Windows Messenger to Skype expecting my contacts to be carried over.  Instead, I lost most of my Yahoo contacts or they were replaced with Skype contacts.  How do I get them back?  If I login to my hotmail account, I can see all the IM's I missed as a result of this issue.

how do i delete history from the computer for when it has been used for the hours or days.

Cometi uma idiotice quando estava com a página do hotmail aberta e apertei a tecla ctrl. O tamanho das letras diminuiu bastante. Aí, apertei de novo a tecla ctrl, pensando que restauraria o tamanho original. Só que elas e toda a janela diminuíram incrivelmente, a tal ponto que não consigo ler/ver o que aparece na tela. Como fazer para restaurar as letras e a janela para o tamanho original? Desculpem-me a mancada.

I am having problems signing into hotmail acct. I called 1-800- 380-4536 as they called themselves hotmail support.  After having me log into another site and allowing them access to my hotmail acct and computer they wanted $199 to fix the problem.  I refused but now am afraid they have accessed all my accts.  I still can't get into hotmail acct.

 como puedo reestablecer mi hotmail a como era antes? se me configuro el outlook solo? y es un desastre desde entonces!!!
depois que baixei o SKYPE não consigo acessar minha conta no hotmail

This just happened today. I have gone to live email and signed in. It says servive is unavailabe. I cannot even get it on my Android. I had my service iyogi check my computer. It is not my computer. They say it is Microsoft. I called and they don't know what the problem is.
