I can not access my account and when you attempt to login a message appears saying it was noted some of the activities is the usual account. Must take action to make sure not to use anyone else for your account

Which account? Your Live passport? Or MyPlus! account? You are being rather vague.

We’ve noticed some unusual activity in your Hotmail account.


Symptoms:
Customers will experience one of the following message when sending a mail:
"We’ve noticed some unusual activity in your Hotmail account. To help protect you and everyone else, we’ve temporarily blocked your account. To unblock it, verify your account."
"We’ve noticed some unusual activity in your Hotmail account. To help protect you and everyone else, we’ve temporarily blocked your account. To unblock it, please contact Support."

What do these messages mean?
We use systems to help detect spammers on Windows Live Hotmail. These systems place a variety of restrictions on accounts, one of them is blocking users from sending emails. Occasionally, suspicious activity causes our technology to apply restrictions on legitimate accounts.

Here are some steps that you can take to avoid getting this error:
  • Check your contacts and recipients lists to make sure that only people who want to receive the messages will receive your messages.
  • Reduce the number of messages that you send to large groups of people so that they are less likely to think your messages are unwanted mail.
  • Limit the number of chain letters, e-mail jokes and other messages that you send to help people recognize your mail as wanted and to make it more likely that your message will be allowed past your recipients' junk mail filters.
  • Check all the contacts in your address book to make sure that the accounts are still active.

Hi

I have a similar problem. That is, when I log in to my account the message appear. So I can not access my inbox or edit any setting.

My email is "albaihany at hotmail.com".
