Unable to send email from outlook.com to o2.co.uk

I’m getting delivery failure error over the last 3 days..anyone else is experiencing this?
Answer #1
I know they were severely cutting down the capacity for some accounts so its possible the one you are sending to is over capacity.
“If you joined Sky from O2 on or before 21 November, you can keep using your existing O2 mailbox for the time being (as well as your new Sky email) but as you have moved to Sky, your O2 inbox storage will be limited to 20MB. If your O2 inbox exceeds this, you will need to remove some emails and stay under this limit to continue to send and receive emails. Transferring contacts and redirecting emails to your other accounts takes no time at all. By following some simple steps Yahoo!, Gmail and Hotmail can be set up to automatically import all of your emails and contacts from your O2 email account and forward any new emails sent to your O2 email account too.
If you are joining Sky from O2 on or after 22 November – great news, you are still able to use your O2 email address with a inbox storage size of 1GB (the same as what you had when with O2). ”
