Outlook Mobile Access is supported only on Microsoft Exchange Server 2003

Greetings.

I'm having the infamous OMA problem on my Windows Server 2003, in which logging onto http://servername/oma gives "Outlook(R) Mobile Access is supported only on Microsoft(R) Exchange Server 2003. Currently your mailbox is stored on an older version of Exchange server. Please contact your system administrator for additional assistance." along with an MSExchangeOMA application error - Category 1000, EventID 1802.

I've followed the MIcrosoft KB 817379 instructions for creating an Exchange virtual directory, with no SSL and with the registry mods. I've used this successfully on several SBS servers, but it doesn't correct the problem here.

Thanks in advance for your help.

Are you doing any kind of redirection?

Trying to redirect to lose Exchange, redirection for require SSL, anything like that?

Thanks for helping out, Simon.

No, I'm not doing any redirection. Here's an added twist: the server starting and stopped serving OMA twice yesterday, without my having done anything to the server.

And here's another piece of information: a few days ago I installed bSafe Internet Filtering on the server to test it out (some of our clients want Internet filtering even on their servers). Any possible problems there?

Anything that interferes with the possible flow of content in or out will always be a concern. If the feature was working before that product was installed and then failed afterwards, then it would be the first thing that has to go to show it isn't the cause.

The error message that you are getting is usually seen when something else is answering the queries, or something has happened to redirect traffic away from /exchange virtual directory. OMA and EAS make internal calls to the /exchange virtual directory, so configuration has to be done with care.

Interference? Traffic redirection? You called it, Simon - lol

My tech forgot to disable the firewall that comes with the Internet Filtering software. We were all surprised that anything worked on that server while the firewall was up. Services like FTP and OMA were flaky - up and down while the firewall was on. To me it's surprising that services were allowed to work at all. Some firewall. . .

Thanks, Simon.
