Outlook 2007 bug on outbound SMTP
 

Upgrading to Exchange 2007 seems to change the behavior of sending
SMTP e-mail through Outlook 2007.

Using Outlook 2003, I could specific an outbound SMTP server and enter
the credentials.

Upgrading to Outlook 2007 changes this. Now I get constant prompts for
entering my credentials.

After playing around with the settings, the way I got it to work was
to uncheck 'My outgoing server (SMTP) requires authentication".

After doing that, I can send/receive e-mail without a problem.

Does anyone have an idea why that is?

Probably best asked in an Exchange group.

I'm going to guess that Exchange isn't really involved here, unless, of
course, the outbound SMTP server is Exchange, but even then, it's probably
not the issue.

Before I actually think about this problem, I have to ask...

If you can send mail *without* authentication, then why do you want it
turned on? Does your ISP require it?

As to the error, if I had to guess, 2003 was a lot more, well... lax when it
came to authentication. Maybe what it did was try to authenticate, find out
that it couldn't, and then just try sending without. 2007 might just say
'Darnit, if my user wants to authenticate, I'm going to authenticate, and
since the logon information he just gave me doesn't work (ignoring tht the
reason it doesn't work is because the server doesn't accept auth) I'm going
to ask for it again.'.
