OWA Stops responding after running ActiveSync

Hi Guys,

Something strange happened now. I removed the SSL configuration from the IIS to see if this's what's causing the problem. But, HTTP didn't also open.

I then followed the second method mentioned in this article:
http://support.microsoft.com/kb/298513/en-us

I deleted DS2MB, restarted the services as mentioned and then OWA HTTP worked again.

I then tried to configure IIS again to work with SSL .. Guess what, OWA Stopped again !!

P.S: Both HTTPS and HTTP was working well a couple of days ago. !!


Any Suggestions Guys ??

Does this have anything to do with my CA ??

if u have a single exchange u must use this article to configure ur exchange server for OMA and activesync to work with SSL...

Dear Vahik,

I'm having a Frontend-Backend Topology.

Did you check the IIS admin and www service on the front and back end servers?

More detail on what you mean by "Both HTTPS and HTTP OWA are not working". Any errors, whats it giving, etc.

Dear Darkstar,

IIS admin and WWW services are running on both Servers. No Errors in the Eventvwr.

The OWA just giving me "404 Error, File or Directory not found"

Hi Guys,

I resolved part of the problem. It's now working with HTTP, HTTPS internally. I reinstalled the CA and reissued the Certificates.

The Problem now is HTTPS is not working from Outside, so when i try to access "https://mymail.domain.com" it's not opening anything.

I monitored ISA 2004 for this and found that the traffic from the external client stops at the ISA Server, i get:

192.168.1.2      443      HTTPS      Initiated Connection      62.114.248.64      External      Local Host
192.168.1.2      443      HTTPS      Closed Connection      62.114.248.64      External      Local Host


"192.168.1.2" Is the External Interface for ISA.

Are you allowing 443 to the exchange server? Did the https://mymail.domain.com timeout, error 404, error 500, etc?

Dear Sarkstar,

I'm allowing all the traffic including 443 from ISA to the Exchange Servers, and i can open "https://mymail.domain.com" from the ISA Server itself.

When i try to open it from outside, i get "The Page can't be displayed"

Dear Darkstar,

Thanks for you help. I solved it.

I just restarted DC, Both Exchange Servers, and ISA. and Everything worked again.

Thanks for your help anyway,
