Certificates and Outlook Anywhere

Recent upgrade of SBS2003 to Server 2K8R2 and Exchange 2010.  Finally got it working... mostly but SSL and server names from intra and internet is doing my head in.  I'm trying to get Outlook Anywhere working and would really like some pointers.

Here's the details:
I have a 2K8R2 AD GC and Exchange 2010 - svrname.domain.local
There are 3 other 2K3 servers still in the domain replicating DNS including the old SBS2K3 which I can't remove properly until I find the SBS discs which have been relocated in a move between offices.
I have an external domain - mydomain.com.au
I have DNS registered for mail, owa, outlook and autodiscover pointing to my public IP
I have local DNS pointers for all the above pointing to svrname
I have an EV SSL Cert from GoDaddy for owa.mydomain.com.au
I have the approriate ports on my ASA5500 open with rules for access and NAT to svrname's private IP.

Users have their Exchange accounts in the office but get certificate warnings
owa.mydomain.com.au/owa works perfectly intra and internet with secure 'green' address
My Blackberry and iPhone users have zero problems
Adding Exchange to Outlook from the Internet:
My Name, my.name@mydomain.com.au and password entered and it starts online search for server settings.  
Establishes network connection then a security alert for name mismatch autodiscover.mydomain.com.au because the certificate is owa.mydomain.com.au.
Click yes and a password request popsup for my.name@mydomain.com.au, change user and enter domain\my.name and the password and get Outlook must be online error.
It then presents a Microsoft Exchange dialogue box with:
Microsoft Exchange Server: SVRNAME.domain.local
Mailbox: =SMTP:my.name@mydomain.com.au
I cancel that box, it ticks searching for server settings for my.name@mydomain.com.au then fails to logon to the server and throws the Outlook must be online error again.

Obviously I've stuffed names somewhere but I know not where.  Everthing I've found online I have followed, GUI Exchange management and Exchange shell setting server names to match the certificate but nothing appears to work unless I use my basic SSL for IIS with CN: mydomain.com.au but then OWA stops working with a 403 .

Having said all that, I'm at home but can get to the office quickly (I haven't set up a VPN for RDP yet) and provide as much info as any of you may request

Include the autodiscover.mydomain.com.au in the SAN certificate with the help of your SSL CA.

As simple as that?  So I can have multiple names on my certificate?  I was wondering as I created the request in Exchange 2010 and made sure owa, outlook and autodiscover were all listed with owa.mydomain.com.au listed as the CN but the certificate only seems to advertise the CN... I'll logon to GoDaddy right now and discuss, thanks R-R!

You want a UCC cert (one that supports subject alternate names). GoDaddy supports I think 5 names on a single cert for $89 US, or something like that...

OK, so I have a new UCC from GoDaddy with:
mydomain.com.au
autodiscover.mydomain.com.au
outlook.mydomain.com.au
owa.mydomain.com.au, and
mail.mydomain.com.au

Same symptoms: Adding Exchange to Outlook from the Internet:
My Name, my.name@mydomain.com.au and password entered and it starts online search for server settings.  
Establishes network connection then a security alert for name mismatch autodiscover.mydomain.com.au because the certificate is owa.mydomain.com.au.
Click yes and a password request popsup for my.name@mydomain.com.au, change user and enter domain\my.name and the password and get Outlook must be online error.
It then presents a Microsoft Exchange dialogue box with:
Microsoft Exchange Server: SVRNAME.domain.local
Mailbox: =SMTP:my.name@mydomain.com.au
I cancel that box, it ticks searching for server settings for my.name@mydomain.com.au then fails to logon to the server and throws the Outlook must be online error again.

Thoughts?

there is something wrong

1. do you have any reverse proxy before your exchange ? like ISA or anything ?
2. when you go to https://owa.mydomain.com/owa and check the certificate is it showing the new one you bought from GoDaddy
3. did you enable the new one in Exchange for IIS use ?

Hi Akhater,

1. No
2. Yes
3. Yes

The Exchange Connectivty tester gives green ticks all the way so I'm at a loss

ok i guess i found your problem

run a get-outlookprovider do you have in expr CertPrincipalName msstd:*.domain.com.au ?

if so run a


Set-OutlookProvider EXPR  -CertPrincipalName msstd:domain.com.au

That was the last piece of the puzzle, thanks Akhater.  I'd just been through and set all three Outlook Provider (EXPR, EXCH & WEB) to server $null which you had suggested in another post but I'd also wildcarded the cert name.  Cheers
