Exchange 2010 #550 5.1.1 RESOLVER.ADR.RecipNotFound
Posted on 2012-09-11
I've been looking for a resolution here and on the web and haven't been able to find the solution that works for us. We've found a couple of articles, but none with enough detail to walk us through this.
We've just installed SBS 2011 and went through the SBS Console to set everything up for us. We have about 10 people that work inside the building, and therefore logon locally to the domain and get their email via POP3 connectors through Exchange, but about 50 people that work outside of the building that get their emails via POP3 or IMAP. Our webhosting company is GoDaddy, if that will help.
Say our website is www.abc.com. Since we've moved to Exchange, the internal users can send to the internal users with email address of email@example.com just fine (they have local Exchange Mailboxes). However, when trying to send to the people using POP3 or IMAP (external users), we receive an Undeliverable email with the errors "#550 5.1.1 RESOVER.ADR.RecippNotFound; not found # #"
I'm sure this is a common issue with wanting emails for people with Exchange Mailboxes to be able to get them via Exchange and those without to get them via the internet. We just don't know how to set it up. Any help would be greatly appreciated.
Thanks in advance.
