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.
