Exchange On-Premise mail queue export
At least I could figure it out myself. It was a combination of VMware and disabling all NTP services. I have disabled the EXSI time sync for the single machines. In Windows safe mode I was able to disable all NTP possibilities and rename the mail.que
This is marked as faulty move, but this is not important for the operation. After starting Windows in regular mode the transport service did not come up, what is great for our purpose. And the most important thing here is, although the transport service is not up and running in this situation you are allowed to execute changes with Set-TransportService.
So I executed...Set-TransportService -Identity Edge01 -MessageExpirationTimeout 90.00:00:00
... renamed the backup.que back to mail.que and started the transport service. As the server now believed in time travel, no messages have been purged.
For erveryone who reads this and wants to know how to export messages...

Are you sure you need to export the queue ? if the relevant messages were sent from mailboxes, you could do a content search instead.
RNalivaikayes, I'm sure, because the mails came from the internet.
Ah, yes I had misread your question.. i would suggest contacting microsoft premier support for that..
