Decommission email services for SBS 2003 after migration to Office 365

We have successfully migrated our client mailboxes to Office 365.
What's the best /recommended approach  to shut off the email services for SBS 2003 server? Is there a specific procedure that anyone follows ?

Secondly, when email profiles are created under Outlook, it resolves locally, is there a way to point it straight to Office 365?

need more details about what have been done. such as:

* existing accounts and their emails have been moved from SBS2K3 to the email services in the Office 365 cloud?

* new incoming and outgoing emails are going into O365 cloud instead of SBS2K3? or in other words, all DNS records have been correctly configured against the O365 cloud?

> Secondly, when email profiles are created under Outlook, it resolves locally, is there a way to point it straight to Office 365?

do you have a local AD domain? and all Windows are managed by the domain?
Did you migrated using cutover procedure?

Once the mailboxes are moved to Office 365. You have to remove the on-premises mailboxes and decommission the Exchange server.

For outlook profiles please check the local DNS for office 365 entries where it is resolving to. Line should point to office 365.
The email profiles should automatically configured to Office 365.
I have just completed a SBS2003 to Office365 migration and just removed Exchange 2003 from SBS tonight.
Once DNS is configured for internal and external domain per O365 and exchange services removed for User  then Outlook setup should resolve to O365.

Yes, it's a cut over migration. All the emails are working correctly using Office 365. We have made the changes to the DNS records for external.

@bbao , yes, it's a domain environment.

We are at post migration stage which will we need to stop the on-premise mail services from running.

Here is my current outline:
1) Run a full back up of SBS server
2) Back up all mailboxes and delete/purge mailbox.
3) Remove Exchange 2003.

Have I miss any steps?
No I don't think so - I removed Exchange 2003 from a SBS 2003 last night and the only thing as a result of doing this was a few multi-function scanners which needed the new SMTP Server Hostname for Office 365.
