Outlook specialist

Urgent!

After a fixing a problem with Outlook I lost all previous contacts. I got them back, but cannot receive emails on outlook in my laptop. However I am able to receive them to my blackberry.

I am able to send emails from both blackberry and laptop. When I send emails from blackberry funny message appears from recipient side: you received email from : .... , please reply to : and it gives email which I haven’t been using for ages . I even do not remember its password.

So I guess that when someone replies it sends it to blackberry and to old email instead of outlook in laptop. Not sure about it, but it might be a case.

Please help to solve it, preferably remotely.
Thank you,
Elena.
