Microsoft Office Outlook Not Sending to all Recipients

[Mickey]

Problem when I send to my whole e-mail group some recipients never get my
e-mails. Mostly affected are those using optonline and some Verizon, I am
sure there are others. As a Barber, I have a large client base with whom I
e-mail.
My service provider Comcast suggested that I send e-mails to those who were
not getting it from Outlook using Hot Mail or their mail program. I did and
they got the mail. Considering this, I looked at my programs and computer as
the source of my problem.
First I checked and the addresses in question are not blocked. I have
upgraded from MS Office 2003 to 2007. Totally wiped my hard drive however, I
did not write zeros to the drive. Once XP Pro was loaded, I manually typed in
my whole e-mail group.
I am running XP Professional so I called them having a few Support usages
left. The XP support team informed me that they have chosen to end their
support, which really sucks. To me that is dereliction of duty and bad
business. My other option is to call their support and pay $48.00 to correct
a problem originating from their software. Dam Bill really needs the money?
Can anyone help me with this ongoing problem? Should I just throw the dam
thing away and go APPLE?
PS
The computer is a duel core with 4 GB Ram.

Maybe recepients, or their mail provider is blocking your mail when you do a
mass mail.
If any mail send from outlook fails then you would have an err msg, within
Outlook
