Hi Nicola,
there is no specific difference apart from seeing many of these errors:

From the Dovecot wiki about ntlm_auth:
Dovecot currently does blocking lookups, so if ntlm_auth is slow on responding (e.g. network problems), Dovecot blocks all other authentication requests until it's finished.
Just wondering if Outlook parallelises it's sessions and ntlm_auth is blocking because of the timing between the requests.
Have you tried a test user with local authentication?
Or perhaps try
auth_cache_size = 1024
To cache authentications.

Thanks Giles :-)
I think that has made things a bit better......
In terms of the cache, is that measured in seconds??
