How can I get rid of the '431 Too many recipients' Error number 0.

[AdrianC]

I tried to send a message to a larger group of friends (137 addresses) and
I got the following message:
The message could not be sent because one of the recipients was rejected by
the server. The rejected e-mail address was '(e-mail address removed)'. Subject
'test', Account: 'mail.xxx.xxxxx.xx', Server: 'mail.xxx.xxxxx.xx', Protocol:
SMTP, Server Response: '431 Too many recipients.', Port: 25, Secure(SSL): No,
Server Error: 431, Error Number: 0x800CCC79
Need help to get rid of this.

Thanks,
Adrian

This is not a Business Contact Manager error.

The error is probably from your ISP, but if you think it's an Outlook
issue you can try microsoft.public.outlook.
