I have posted previously about this but had no replies, so I'll be a precise as possible and try not to waffle.
Basically, I have set up Exchange 2007 SP1 to use the same Autodiscovery FQDN internally as externally as set out in exchange_ginie's blog, in order to get around the certification issues. Internally the Autodicover seems to work well and OWA works internally & externally. However Outlook Anywhere will not work at all internally or externally, it will repeatedly ask for the login credentials and will continue to do so until you are blue in the face.
When I run Test_OutlookWebServices |fl in the Exchange Power Shell, It finds the url and then gives a 401 error for unauterised. I have tried to Disable the Loop Back Check in the registry as discribed by exchange_ginie's blog, however this does not fix the 401 issue, so I am unable to get any further with my trouble shooting.
Please, please, please.... ANY help would be gratly appriciated on this issue
