Re: OMA not implemented issue

Hi,

Why did you create another 'Web site identifier'? This should not be
necessary when using front-end servers.

This might help:

Hi all,

We are using Win2k3 / Exch2k3sp2.

I have our webmail successfully secured using SSL and this works fine from
the internet and internally.

However, I am now trying to implement OMA and this does not work. I
receive
the following error message in the event log of the front end servers:

----------------------------------------------

We have 2 front end servers configured in the DMZ as webmail servers, and
are also our mail relay servers.

In IIS, on the default website I have added another 'Web site identifier'
entry similar to the existing one except this one has the host header
value
equal to the FQDN of the server.

On the default web site I have enabled SSL, however I have disabled this
on
the OMA virtual directories. Should it be configured this way, or should I
be
disabling SSL on the default web site and enabling it on the /exchange
virtual directory only?

In the ESM I have disabled forms-based authentication on both servers.

Any help anyone could provide I would be most grateful.

Thanks

Andoni
