you might get an NDR 550 550 5.4.1 Relay Access Denied (state 13). when you move to office 365 #office365 #msExchange #microsoft
you might have seen that error, or you might get it if you deleted your domain from Office 365 and migrated it to a new account, or recently created your domain, or it has been a period of de-activation, the reasons might vary but here is the solution:
- follow the steps here to connect powershell remotely, http://help.outlook.com/en-us/140/cc952755.aspx
- issue the following command: set-acceptedomdain <domainname> –outboundonly $True followed by set-acceptedomdain <domainname> –outboundonly $flase
you will have to wait 30-45 minutes for information to propagate to Edge servers cloud @ Microsoft.
