is this a scam or what as i dont know and dont want my account shut down,they say last warning ,need account pass word,birth date and other personal info,it said from hotmail team.last warning or account will be lost.

im just a old 40 +year old mom that has only been using computer for 2 years,what should i do.

my account that i used a few years back cant be accessed because it doesent exist, but when i try to make another with the same email address it says its taken???. i cant access it and it has alot of important info that i require now, no help sites help me so please "help". my facebook account uses this email and i can access that fine so i have proof of its existence if needed. it was an old hotmail account from before they changed the sign in page and it uses @hotmail.com, just encase if this info helps.
I use Outlook Mac 2011 v 14.2.3 and OWA with a hosted exchange to push my email info to 4 devices (iMac, laptop, iPad, iPhone). All worked perfectly until a couple of months ago, when I had a big freeze due to being too close to my storage capacity. I got it functioning but I have 1 residual issue. When I delete an email message on my iMac by clicking the delete button, it does not sync. The email remains on OWA & my 3 other devices.  Clicking delete works fine on my laptop, i phone & ipad; and the sync works if I drag the email to the trash on my imac. But clicking the Delete button on my iMac only deletes the email on my imac (not the owa server, not my other devices). I've done all the suggested things (deleting preferences, rebuilding the identity, etc) except for a total un-install and re-install of office. Any ideas? Thanks!
I just began having a problem with having to sign in everytime I want to go to my hotmail acct. Before this after I had filled in info and checked keep me logged in I never had this problem. Why is this happening.
