Hi,
I just run the HCW and got below error. i think my firewall should allow 443 to new server?
HCW8078 – Migration Endpoint could not be created.
Microsoft.Exchange.Migration.MigrationServerConnectionFailedException
The connection to the server ‘webmail.domain.com’ could not be completed.
Microsoft.Exchange.MailboxReplicationService.MRSRemoteTransientException
The call to ‘https://webmail.domain.com/EWS/mrsproxy.svc’ failed because no service was listening on the specified endpoint. Error details: There was no endpoint listening at https://webmail.domain.com/EWS/mrsproxy.svc that could accept the message. This is often caused by an incorrect address or SOAP action. See InnerException, if present, for more details. –> Unable to connect to the remote server –> No connection could be made because the target machine actively refused it 202.183.94.21:443

Other issue is when i set send connector to new server mail queued?
Do i have to enable port 25 from this server?

@aussupport the error states the call to https://webmail.domain.com/EWS/mrsproxy.svc so no port 25 here, this would be the port 443.
also please check if you have allowed the IPs and URLs of Office 365 in your network.
