The problem with the message queue

Question

Hi

The organization has Exchange 2013 and 2016 servers. Exchange 2019 servers have recently been added. Migration is planned in the future.

I see that emails are stuck on Exchange 2013 in the queue for transmission to the Exchange 2019 server :

[[PS] C:\Windows\system32>Get-Queue MAILMBX02\221361 | fl lasterror

LastError : [{LRT=10.04.2024 17:35:02};{LED=441 4.4.1 Error encountered while communicating with primary target IP address ess: "421 4.4.2 Connection dropped due to Socket Error."

Attempted failover to alternate host, but that didn't not succeed. Either there are no alternate hosts, or delivery failed to all alternate hosts. The last endpoint int attempted was 10.107.227.153:2525};{FQDN=mail06.main.msa.com};{IP=10.107.227.153}]

All emails are addressed to migrated mailboxes. On mail05 in the log "C:\Program Files\Microsoft\Exchange Server\V15\TransportRoles\Logs\Hub\ProtocolLog\SmtpReceive\RECV2024100414-1.LOG" I see:

TLS negotiation failed with error Algorithm Mismatch

TLS 1.0, 1.1, 1.2 are enabled on all Exchange servers

What could be the causes of this condition? What is the configuration error?

Всем доброго дня.

По русски.

The organizВ организации имеются серверы Exchange 2013 и 2016. Недавно был добавлен сервер Exchange 2019. Предполагается в дальнейшем миграция.

Я вижу, что сообщения застревают на сервере Exchange 2013 в очереди для передачи на сервер Exchange 2019:

[[PS] C:\Windows\system32>Get-Queue MAILMBX02\221361 | fl lasterror

LastError : [{LRT=10.04.2024 17:35:02};{LED=441 4.4.1 Error encountered while communicating with primary target IP address ess: "421 4.4.2 Connection dropped due to Socket Error."

Attempted failover to alternate host, but that didn't not succeed. Either there are no alternate hosts, or delivery failed to all alternate hosts. The last endpoint int attempted was 10.107.227.153:2525};{FQDN=mail06.main.msa.com};{IP=10.107.227.153}]

Все письма в адрес мигрировавших ящиков.На сервере mail05 (Exchange 2019) в журнале "C:\Program Files\Microsoft\Exchange Server\V15\TransportRoles\Logs\Hub\ProtocolLog\SmtpReceive\RECV2024100414-1.LOG" я вижу:

TLS negotiation failed with error Algorithm Mismatch

На всех серверах включены TLS 1.0, 1.1, 1.2.

В чем может заключаться проблема?
