I am having issues with emails being returned. Either internal or external emails. I have included errors on both:
I am using a hosted exchange and I can send via OWA with no problem. But, when I send via Outlook 2010 or 2007, I get#550 5.1.1RESOLVER.ADR.ExRecipNotFound; not found ##error when I try and send to someone within the company, but not everyone. I also get bounced emails when I try and sending outside our domain. The returned emails are never repeated on same email address but I get returned emails daily.
error on external emails:
IMCEAEX-_O=MYVENYU_OU=EXCHANGE+20ADMINISTRATIVE+20GROUP+20+28FYDIBOHF23SPDLT+29_CN=RECIPIENTS_CN=AndyShealy+5FLou@myvenyu.com
#550 5.1.1 RESOLVER.ADR.ExRecipNotFound; not found ##
The email address show in the error is not our domain but rather our hosted exchange domain.
