My mac book won't let me send any e-mails anymore, none what so ever.

Whenever I try to send an e-mail something pops up and says: Cannot send message using the server smtp.live.ca.

The sender address .....@hotmail.com was rejected by the server smtp.live.com. Select a different outgoing mail server from the list below or click Try Later to leave the message in your Outbox until it can be sent.

But when I go and try to select a different outgoing mail server theres no other ones!

How do I fix this problem so I can finally send e-mail?

    Try Deleting the account in Mail Preferences and reading it. It looks like the mail server credentials got changed.

    Hi mikhemil,


    We rely so much on email, it can be frustrating when it is not working.

    Hopefully these troubleshooting steps will get you back on track ...

    No this does not help. I did this first. It has been very exasperating for several months. Mail always comes in, sometimes it goes out, sometimes it doesn't. Sometimes it goes out from one account, but not from another. It's worse when the internet connection is slow - but not always. Sometimes only emails with attachments won't go out. Right now nothing goes out- not even a one-line response to my mom. I have gone through these steps several times. I have deleted and re-added the accounts. I have totally given up on my work email account- it works fine on my iPhone, always has, but I can never get it to send off the MBA so I just have to go to the website whenever email comes in.


    IDK if I need new system software (I am running 10.7.5), a new email program. (currently running 5.3) or what to do. I have had at least two "computer geek" friends look at it, and I went to the MacShop with it once but of course it worked fine that day...
