Our company was hosting 2 email domains on our exchange server. For example *@domaina.com and *@domainb.com. &nbsp;The company split up and now the people who use domain B have their own office and their own server. That is working fine however people at the original company domain a cannot email people at domain b at the new location they get. The e-mail address you entered couldn't be found. Please check the recipient's e-mail address and try to resend the message. If the problem continues, please contact your helpdesk. On the original server I removed the domain accounts, the address from the default domain policy but I don't know what else to do. How can I get it so users at domain A can email people at domain B. its like something on the server is still seeing the address.
