Windows Live Hotmail - problems?

I use Hotmail even before it was bought by Microsoft. And I'm very satisfied with it.
Now I can use it in Firefox and Safari with almost the same characteristics as from Internet Explorer and we have more storage space to enjoy.
But today I had a unique problem that I hope will be solved fast:

"Windows Live Hotmail couldn't send your message because the server was busy. Please try again later".
I'm posting this message with the hope that some guy from Microsoft would check it... and take it to the right hands. I think it is a critical problem to solve.

Free services: How to use the best out of free email accounts?

There are 2 services I'm using for information storage. One is Gmail and the Other AOL mail. Each one offers 2GB at least for storage.
Here is the tip:

1. I use an email address in the office. That one is the most important for me. I also use one Hotmail for personal messaging, I have this account since 1997! the only problem is that until now I don't get the 2GB of storage!
2. When I want to backup any email and attachments I just forward it to my Gmail account.
3. I made a rule on the Gmail to automatically forward all incoming emails to my AOL mail account. (Click here to learn how to do it)
   

That means that I centralize into those 2 backup accounts all what I think is important. If one service is not available is very possible that the other is.
Of course those accounts are also helpful to subscription to some newsletters that I don't want to receive to my job's email.
