Searching forums and web, there are a number of references to this error,

but most are for the 403 whereas the error we receive in the application log is 400.

 

As mentioned its a tricky one. So far I have verified according to kb docs and others sources.

-OMA vdir is set to basic authentication, domain is set to "our domain". (In fact all of the

relevant vdirs: OMA, exchange-oma, microsoft-server-activesync, Exchange, Exchweb, have been

double checked against an SBS server that does work for authentification and SSL.  


-.net framework 1.1.4322.573. Reinstalled: "aspnet_regiis.exe -i". Although one curiousity is that the ASP.NET

tab does not appear on this server.


-ExchangeVDir key is set to the proper exchange-oma vdir

-no host headers on default web site and using the standard ports.

-have re-run the CEICW

-Mobile access IS enabled globally and individually

 
Error message in log is as follows:  Source: MSExchangeOMA, Category:(1000), EventId:1805

Request from user test@BCN.local resulted in the Microsoft(R) Exchange back-end server SERVER1 returning an HTTP error with status code 400

If you look in IIS, Servername > Application Pools.  Do you have an ExchangeMobileBrowseApplicationPool?  With a directory below for /LM/W3SVC/1/root/OMA?

Also, if that's there, can you access OMA via http://localhost/oma ?

Ah... in testing this on my machine I just noticed that my .Net Framework is version 1.1.4322.2300 which is SP1.  You need to install that.

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

Hi Thanks for your suggestions but I have just managed to fix it.  We had changed the host header on the company web to server1.  When we changed it back to companyweb it worked fine.

oh... that would probably be a problem... but you still should patch .Net Framework when you get a chance.
