1) microsoft has a rule: max mail size with attachment is 25 mb.   It does not state it is per email or per account?  Base on what just happen to me, it could be per account??    If you go over this limit you can not receive any email with any attachment even with 2k size.    If you contact microsoft oline help they can not help and stating they do not know and want me to contact this channel?  In the mean time, I can not use hotmail service?  I can only send out email, no one can send me any email with attachment.   See below descriptions.

2) What has happen:
When I sent out email with attachments and cc myself a copy, I get an error message saying my email address can not receive email.
so I did the followings:

I delete all my mails in inbox, junk box and deleted box
I go to my gmail account and send me myself 2 emails, one with attachment, one without

the one with a 2k size attachment and get the following message

Final-Recipient: rfc822;*** Email address is removed for privacy ***
Action: failed
Status: 5.2.2
Diagnostic-Code: smtp;552 5.2.2 This message is larger than the current system limit or the recipient's mailbox is full. Create a shorter message body or remove attachments and try sending it again.

I sent one without attachment, just text, it went through

Contact microsoft, help desk can not help?
This is the no. 1   software company's service record?

3) What microsoft can do for me now or when microsoft can do something: today is sept 8, 2013, 11:10 am?

In the mean time, I'll miss a lot of business related and important personal emails
reliability is important
time is of essence
