Can't connect to OWA internally

Hi guys,

I'm having an issue trying to get a Entourage to connect to our Exchange server and I believe that the problem is due to us not being able to access OWA internally. It was also effecting just getting to our externally hosted website, but I've create a new forward zone and A record for the www.domain.co.uk to point to the IP and that works fine now.

Exchange server is:
Router is: (with port forwarding configured for port 80,443,25 and all standard ports pointing to

A record for mail.domain.co.uk is pointing to with the PTR corresponding correctly with this, but when I try to go to mail.domain.co.uk using HTTPS internally I get Internet Explorer cannot display this webpage. If i use HTTP it goes through to my router management page...

I also created a new forwarder for another domain that we own and created an A record on that to point to https://mail.domain.co.uk/owa which would be www.forwarder.co.uk but I get the same error as using HTTPS.

We have a work around at the moment using pop accounts but for obviouse reasons we need to get the mac working with Exchange.

Any help is really appreciated - I'm confused by this one entirely!!

Entourage works like Outlook
Open entourage, add account
do setup manually.
when it ask for the server name use the IP as you did not added the AD to iMac
as this will allow you to use the name.
then it will ask you to use SSL and if port 443 is open and then you can select ssl but just use the IP.

let me know your status, as I do this setup everyday!

Have already tried this but had no joy. From my research Exchange 2007 you need to use the owa address with /exchange/username on the end, but as we can't connect to owa internally this isn't working.

As I've said.. the problem is that we can't view OWA internally. Once this is sorted the Mac should connect fine but I can't see where the OWA issue is, it works fine externally but internally it can't be opened.

As you're trying to connect to mail.domain.co.uk, make sure that 'nslookup mail.domain.co.uk' resolves to the internal address of the OWA-server.
Create A/CNAME record in internal DNS-zone to point on the internal server address. If mail.domain.co.uk is the only address that shall be resolved internal and domain.co.uk is normally used for external addresses, create a new DNS-zone on internal DNS-server named mail.domain.co.uk and place a record in that zone without name (same as parent) pointing on the correct internal address.
