"we run ESET Mail Security for Microsoft Exchange Serverv.7.1.10009.0"
Are the Exchange dirs excluded? Does it start if you disable or remove the anti-malware software?

… it says starting, but fails and keeps retrying & we are panicking!
Environment
Symptom
Last week:
Whilst doing host (not the vm) updates saved and then resumed all servers. "Microsoft Transport Service" showed as starting and no e-mail was flowing. Weird as save / resume shouldn't have stopped any services. We don't have amazing notes, but restarted all servers. Same. Then about 30 minutes later the service just seemed to start and was OK.
Today:
Installing OMSA on host and as a precaution saved the VMS (Exchange followed by other servers)
After the VM state was Saved and then Started again, the "Microsoft Exchange Transport" Service was showing as 'Running', but we received an error when in the Exchange Mail Queue to say "Exchange can't connect to the Microsoft Exchange Transport Service". We then rebooted the Server VM and the Service status changed to "Starting" where it get stuck for a period of time before showing as no status, and then starting again. Each time the process ID for the MSExchnageTransport.exe would change.
Event Log of failure:
14001 - MSExchangeTransport - "The worker process with process ID 20024 is not responding and will be forced to shut down."
What we've tried
Rebooting the server again
Disabling the service so that it stopped on its next restart attempt (it looks like the service attempts to restart every 15 mins or so), moved all of the contents out of the ..\TransportRoles\data\Queue folder before changing the service back to automatic & start, so it attempted to re-start, but it again got stuck on Starting.
The Queue folder is populated with same files as we removed (although the mail.que is smaller).
Checked the Event Logs and we can't see anything in particular that may be causing the service to not start properly.
So we are stuck. Really could do with some help here.
Thanks in Advance - Jason

"50 Users all using Outlook (2013 or 2016), none using it at the moment"
Does this mean the server is not in production?
Can you build a new server and move mailboxes? Maybe use this to upgrade to 2016/2019?
