HI Guys,

My Email Router is reporting all pass on the Test Accesstab, but when an email is sent through the CRM online client I get 5.7.1 unable to relay in the event long on the server with the email router installed.

I am out of ideas for what the prblem could be now, some help is needed.

some backgroung info, if i missed anything ask, I have three servers:

exchange (10.10.1.15)
CRM (10.10.1.7)
Email Router (10.10.1.13)

exchange has a recieve connector:

Local Recieve IP - All
Remote Recieve IP - 10.10.1.13, 10.10.1.15 and 10.10.1.7
Auth - TLS, Exchange Server, Intergrated
Permission Groups - Anonymous, Exchange users, exchange server, legacy exchange

Email Router

Incoming

Protocol - WebDAV
Server Type - Exchange 207 or earlier
Auth type - Windows Auth
Server - URL to OWA
Credentails - a domain Admin

Outgoing

Protocol - SMTP
Server Type - SMTP
Auth Type - Windows Auth
Server - servers internal domain name
credentails - a domain admin

the router service is running as a domain admin - the same one in all three places

Hi Stuart,

Typically when I see the 5.7.1 error in the event log it is an issue that is related to the receive connector in Exchange.

I am a little confused by your posting. So are you using Microsoft Dynamics CRM Online or are you using Microsoft Dynamics CRM On Premise? I see you list an IP address for Microsoft Dynamics CRM, though you also mention you are using Microsoft Dynamics CRM Online.

What errors are in the Application Event viewer on the Exchange server that occur at the same time as the 5.7.1 error?

Is the server that is listed in the Outgoing Profile the same as what is listed on the General tab for the FQDN? If not, please copy that over to the Outgoing Profile and test sending an email again.

Does it make a difference if an email is sent from Microsoft Dynamics CRM to an internal user or external recipient?

Cheers,

Jason Kirkeby

Found that this was caused by incorrect authentication type in the recieve connector. removing everything except External Auth fixed the problem.
