Exchange 2007/OWA authentication query (internal/external access)

Hi guys,

Internally, staff use OWA to access email. I am using integrated authentication so once they have logged onto the network, they do not need to retype their credentials when opening OWA.

I am also about to set up OWA for external access, but my testing has shown (obviously) that I have to type the FQDN and user details to access OWA (via standard login box, not OWA). This is obviously unacceptable.

My query is this, is there a way I can have integrated when internal, and forms based when external?

Thaanks in advance...

Ben

Hi,
via Exchange shell you can use the 2 different parameters .
ExternalAuthenticationMethods and InternalAuthenticationMethods of the commandlet set-owavirtualdirectory
see http://technet.microsoft.com/en-us/library/bb123515(EXCHG.80).aspx for all possible probperties.
and try get-owavirtualdirectory to see your current settings.

Thanks mikainz,

I am trying the following command and using iisreset /noforce after running but external access still asking for FQDN... internal access to OWA fine and logging in automatically using inegrated auth.

set-owavirtualdirectory "owa (default web site)" externalauthentificationmethods fba

I am suuming it is fba for forms based... can't seem to find full paramaters

what do you mean by
"external access still asking for FQDN... "
FQDN means Fully Qualified Domain Name, so this has nothing to do with auth.

When I try and access OWA externally, outside of my domain (from home as an example) it brings up the windows log in box (not the owa login) and I have to type in mydomain.dom/username before it lets me get to OWA.

Points bumped up to 500.

I would like comprehensive instructions on how to achieve the above please...

Internal OWA using windows integrated authentication whilst external access to OWA to use forms based. I think I may need to create a second site in IIS but am unsure. Step-by-step idiot guide preferred.

Please help,
