Removal of Accepted domain and moving the domain to mail hosting company

Greetings!!

I have to move one of our partners domain from our exchange server to another mail hosting provider.  The migration of the domain to the mail provider was fine.  They are able to send and receive emails normally.

After this I removed the accepted domain from our exchange server.  The following steps were taken.

1. Backup of the mailboxes
2. Remove mailboxes
3. Remove mail policy
4. Remove the accepted domain
5. Remove DNS from the network.
6. Updated the off-line address book

But still unable to send the domain now hosted outside our exchange.  Getting the following error.
#550 5.1.1 RESOLVER.ADR.ExRecipNotFound; not found ##

Any assistance will be highly appreciated.

Regards

So, you able to send an email via OWA and Outlook then.

It is a outlook cached offline address book issue. You may rename the xxxx.oab to xxxx.oab1 then let Outlook create a new oab for you. Close Outlook before renaming the oab

What is you mail flow before this? do you any mail gateway installed? if yes, have you register the domain on it?

Have you restarted the Hub Transport server after deleted the accepted domain?

Could you send a another test email and use message tracking to track the email flow.

What you did shall allow email to send out.

I dont have any gateway installed on the server.

I have not restarted the server.  Do i have to restart the whole server or just Exchange services.  Is restart required

I will test with message tracking.

You are right that I should be allowed to send email.  I followed a microsoft article but still didnt work.

How long you wait before send the email? it is more than 2 hours?

Please wait for 2 hours and then send a test mail and use tracking message to track the email.
