Some users not receiving email - while other are - cant send emails between users

Post by ovant »

Just loaded a large number of users using the windows power shell.
Set-MailEnableMailbox -Postoffice xxx.com -Mailbox yyy -Setting mailboxLimit -Value 528000

These users are not able to send emails to each other, while some can and some cant, they can however send email out but they are not receiving emails at all. Error: Reason: Remote SMTP Server Returned: 503

Checked and followed the instructions on https://www.mailenable.com/kb/content/article.asp?ID=ME020531

Any advice?
