Dear All ,
Below is our Server configuration
Exchange 2K7 SE w/SP1 running on Windows 2K3 x64 En R1.
ISA 2K6 Enter w/SP1 running on Windows 2K3 Ent R1.

We had OWA working fine Through ISA 2006 SSL.On 6th March 2010 our self -signed certificate of Exchange2007 expired so we had to renew it .After renewal we were unable to connect to OWA internally .We worked on it to make it fine by modifying IIS 6.0 on Hub Transport Server .
Now we have the problem to connect to OWA through ISA server .
Whenever I try to connect First I have to fill in Authentication form of ISA & then in Authentication dialogue of Published server & then the below error occurs :
HTTP/1.1 503 Service Unavailable

As I am able to connect to it via internal but not through external & nothing has been modified through ISA so I am messed up.

thanks in advance ,
P.S.Certificate on ISA which is for webmail is valid till 2012

hi
I forgot to comment that everything was fine & working Until we uninstalled Norton Mailsecurity for exchange which has expired .This program had occupied port 80 of iis on both Hub Transport & Mailbox role server .After uninstalling it gave a prompt to unregister itself from Davex.dll .

The day after we saw that self signed certificate for exchange2007 had expired due to date .We renewd it & installed Webmail certificate on Hub Transport server .

the day after one of our colleagues that had gone for mission announced us that she can not get into OWA .

I thought that this may help to give me precious hints .

Thanks in advance.

After checking the problem ,we came into underestanding that /exchange folder of IIS 6.0 is corrupted cause users are able to connect via https://domainname/owa .

I was instructed to install Exch2k7 SP2 on servers to overcome this problem while trying to install SP2 :
