Greetings,
The Exchange 2013 not supports outlook 2003. due to that I have to configure exchange account as POP3 account, but after configuration i am receiving the following error. "Your message did not reach some or all of the intended recipients, Server error: '550 5.7.1 Unable to relay'"
I can send emails within the organization but not able to send mails to outside of organization.
Regards,
Damodar Mahajan
