OMA not working after perform SSLOffLoad registry change   
Hi there,

We install SelfSSL in your Exchange to generate a SSL cert for our OWA. We 
also have SSL terminated in our reverse proxy for external access to our 
OWA.

Where we have put below registry configuration to make that work

REG ADD HKLM\SYSTEM\CurrentControlSet\Services\MSExchangeWeb\OWA /v 
SSLOffloaded /t REG_DWORD /d 0x1 /f

With these OWA work perfectly well, however, we notice that kill our OMA.

We always get below error on OMA after user login (login directly to the OMA 
server without any proxy)

A System error has occurred while processing your request. Please try again. 
If the problem persists, contact your administrator

Anyone has similar issue ?

Exchange 2003?  If you require SSL on your OWA, then you need to do this:

1. Remove SSL on OWA to get OMA working again.
2. Do this:  http://support.microsoft.com/kb/817379
3. Put SSL back on your OWA.

Lee.

Re: OMA not working after perform SSLOffLoad registry change   
I have try the according to the microsoft support site suggested (the 
solution 2).

However, I notice when I use Window Mobile device to access 
http://server/exchange-oma I got the OWA page that does not work with mobile 
device.

Did I miss out something ..

Re: OMA not working after perform SSLOffLoad registry change   
The /exchange-oma address is not meant to be accessed by the mobile device. 
You still need to go to the original /oma address.  The  new /exchange-oma 
directory that you created is for internal use by the server.  What happens 
is that when you go to /oma , the server then makes a request of its own to 
/exchange .  But if you have required SSL on /exchange, then /oma breaks. 
So, you need to make a copy of /exchange called /exchange-oma , and tell the 
server to use that for its internal call instead.
