Exchange online is throttling then failing emails sent via Exchange 2016 pickup folder under the error {LED=550 5.7.230 Connecting Exchange server version is out-of-date; connection to Exchange Online blocked for 60 mins/hr.
Exchange 2016 server on-prem is fully up to date, doesn't appear on "Out-of-date connecting on-premises Exchange servers" & emails sent via traditional relay are being delivered to Exchange online without issue.
Anyone know how to resolve the issue where Exchange on-prem server is stamping wrong build number onto message sent via Pickup folder?
