there are 2 reasons, either a transport service stopped so make sure that all of Exchange services are started, the other is back pressure so you might have a resources issue on the Exchange server

test-servicehealth returns all services started:
Role                    : Client Access Server Role
RequiredServicesRunning : True
ServicesRunning         : {IISAdmin, MSExchangeAB, MSExchangeADTopology, MSExchangeFBA, MSExchangeFDS, MSExchangeIMAP4,
                           MSExchangeMailboxReplication, MSExchangePOP3, MSExchangeProtectedServiceHost, MSExchangeRPC,
                           MSExchangeServiceHost, W3Svc, WinRM}
ServicesNotRunning      : {}

Role                    : Hub Transport Server Role
RequiredServicesRunning : True
ServicesRunning         : {IISAdmin, MSExchangeADTopology, MSExchangeEdgeSync, MSExchangeServiceHost, MSExchangeTranspo
                          rt, MSExchangeTransportLogSearch, W3Svc, WinRM}
ServicesNotRunning      : {}

How can I check that "back-pressure"?

BTW: e-mails sent using outlook client are processed correctly. OWA was also working until a couple days ago and I can't track any change in the last few days. We're trying to go live today... :S

Doesn't seem to be the issue: changed the existing value to false, restarted the service, tried again and problem persists.

can you remove the OWA virtual directory and then create it again, also try from a client machine not from the server itself.

do you see any errors in the event viewer

do you have an outlook client left open in a terminal services session ?
Can you close all outlook clients for the mailbox and then try again ?

Are you using any add-ins in outlook

Also

start > run > services.msc
Can you check the hub transport - logon account ?
Is it local system account or network service ?
it has to be a network service.

@busbar: I'm not very confident w/ exchange to remove and re-install owa right now! :) Maybe as a last resort option. besides, even if that would fix the problem, I would not know *why* it happened and would risk it coming back again sooner or later.

@sunnyc7:
1) No outlook clients running;
2) The problem is only w/ OWA: I can send/receive e-mails w/ pop/smtp connected clients using the same account;
3) It's not mailbox specific: happens on several users I tried so far;
4) No such errors in event log;
5) Microsoft Exchange Transport service is running as Network Service: attached is the list of exchange related services and their accounts for our client access/hub transport machine. Mailbox server is a different machine, should that matter.

@sunnyc7:

4) No such errors in event log;

As for the SID, yes, I've just discovered that these VMs all share the same SID... We hired the service of a "professional" exchange company, so I find it odd they made such a basic mistake.

Thing is, we have now deployed these servers in production so I'll open a ticket w/ MSFT today to see if we can fix this quickly. If it turns out to be the SID problem, I'll credit the points to your answer.

Removing and re-creating OWA virtual folder did help but didn't completely fix it. I have since, upon recommendation from MSFT, upgraded to SP1 and all is fixed now. Crediting the OWA re-install answer as it was the closest to solving the actual problem. Didn't mention to MSFT that the machines had the same SID, but they also didn't ask and all seems to be working just fine...
