I was trying to send a letter with 350 to 450 words in it, and I got a delivery failure notification.....What length limits are there on hotmail?

Cela fait 1 mois que je ne peux plus ouvrir ma boite messagerie HOTMAIL,je n'ai accès que sur windows live mail que je n'aime pas.

Je vous ai envoyé xxxxxxxxxxxxxxxx messages sans reponses réélle de dépannage si ce n'est que des renvoi vers des sites microsoft answers ou autres ou je n'ai pas de réponse pour mon dépannage.

On my hotmail sign-in page is what I guess is somewhat of an add telling me to schedule a cleanup and would I like to know how. It has a big clock with an arrow pointing to a file. I'm sick of looking at it.
When I enter events on my hotmail calendar and put the reminders in, none of them pop up like they used to. They should show up after I sign on to my hotmail page, but they don't. I'm pretty sure I'm doing it correctly; I'm putting the info in no differently. When it says add reminder, it's self explanatory. I just do as it says.
When I sign-in to Hotmail for past 2 days, I have been unable to see my Inbox page.  Has my Hotmail been hacked?
