Please click on "Options" in your post, then Edit,  and redact the user ID in those email addresses.  These are public forums and spammers can see them.  Fill them in with xxxxxxx or something.

Okay, I've stripped out everything but the error.  This is a fun way to get support!

This is an odd one. (trying from several different places) Sometimes the server for @cambridgeexecutiveservices.com accepts that address, sometimes it doesn't. When it doesn't, it responds with

 

550 No Such User Here"

 

which doesn't match the error message above. Which suggests that that message was refused at a later stage in the SMTP transaction than when the recipient address is submitted; you can't tell exactly what went on from the info Comcast provides, but the 5.1.1 Status code indicates that things went wrong after the point where the sender adress is submitted, which is the first bit in the SMTP chit-chat. When I first tried yesterday that trailing quote wasn't part of the error message, which suggests that they might be mucking about with things.

 

That's probably more than you wanted to know. ;-) But the bottom line is that there are problems at the recipient end.

I hit reply all in Outlook for Mac 2011, 35 recipients. I get the message 5.1.1 not our customer. If there is a problem with one email address, does not prevent all from receiving it? thank you

I know i"m a little late to this.. but.. did you check what youre reply-to address is? Are you sending with a different name or reply to address? That *could* also cause a rejection.
