Two quick thoughts:
Does this happen with all users at the same time? If not, try shutting down
Outlook and deleting the user's OST file. Restart Outlook and let it create
a new OST, and see if that solves the problem. Obviously if all the users
are seeing the symptom at the same time, it wouldn't be this.
Also, in ESM, in the properties of the Default SMTP Virtual Server ->
General -> Advanced -> Edit, is the Sender ID Filter enabled? I had this
symptom after enabling Sender ID when Exchange services would restart - for
example, IMF updates, services restart, incoming mail stops flowing. At
that point, I'd get the service hang at "stopping" as you describe and have
to reboot the server. It might explain the seemingly random nature of this
if you have Exchange restarting from something like WSUS. This KB is what
fixed it for me, even though the symptom didn't really match the KB.
Messages from some organizations may remain in the queue folder when you
enable the Sender ID filter feature in Exchange 2003
