Question about Outlook Express

ONLY happens the first Friday of every month.  Second month in a row with this BS.

Send emails out during the day Friday.  Get delay notices on Friday night/Saturday morning (email send time +12 hours).  Will get failure notices Saturday/Sunday (+48 hours form send time).

Emails going to too many different domains for them all to be down (4.4.7). Aol; Gmail; private;

The one incoming email that came in at 1:17am is blanked for privacy.

I have no issues with incoming mail - but outgoing... Second time this happened, last time was exactly one month ago, all emails that went out on Friday - were bounced back as delay - and failed by Sunday/early Monday.

WTF - Outlook.com?

(also - MS - please don't try to tell me that it is something on my end - because I have no issues the other 29/30 days of the month, and the last time a tech remoted in to "fix" my problem - they regedited me out of my existing office mail profile; office install; and blew out the system so bad I had to call in to re-activate windows). 

The email goes out, it is shown as sent in outlook on my desktop, and in outlook.com, and the Win 8 Mail app.  Don't have some level 1 tech idiot tell me that the problem "must be on your end"/"your office install is bad"... the mail goes out - your server receives it - how can it be a problem with my desktop AND tablet AND laptop.  It is mail that goes out through this account - no matter which machine or application it is sent from. 

First Friday, past two months.
