Why do i have this message :
550 5.7.1 RESOLVER.RST.AuthRequired; authentication required
When the transport rule is to transfert email to an universal distribution group ?
my goal is to make a rule to do support@xxx.fr transfert to internalsupport@xxx.fr (internalsupport is an universal distribution group)
Thanks for your soon answer.
Best regards.

I have found the solution
There is a something to uncheck in the distribution group / restriction
check user authentification

José,
I've got the same problem over here. Can you remember what you uncheck? I've been searching for over a day now.
--edit--
Ok I've solved it;
On the distibution group goto the tab Mail-flow, open message delivery restictions and remove Require authentication. So thank you for the lead.

Thursday, May 07, 2009 12:52 AMThis worked - thanks for saving my time.
So the question is "Why is this set as default by Microsoft?"
I've had issues whereby I needed to delete the recive connector and recreate it for it to work so try this if you are still having the issue. -
