I have Exchange 2003 with Active sync enabled across the organisation, (not that we use Windows based mobile devices, we have BES) and I have ensured its also enabled at the mailbox level for a specific user who has an iPhone which I would like to have working with Exchange.
in IIS on the Exchange 2003 server, the OMA settings and virtual directories I believe, are correct, with Script Source, Read/Write & Directory browsing enabled. Execute permissions are set to scripts only, and the application name is populated with /LM/W3SVC/1/root/OMA. (I've read various articles about removing this).
If I run a connection test against the Exchange environment, it tells me ActiveSync is detected, but NOT enabled for the user, access denied (403) however it is. I'm not using SSL.
Also, our Watchguard firewall is configured to allow the Activesync via 443 and 80 through.
My weakest area of knowledge in all this, is the virtual directories, I dont want to mess up anything which may effect BB users, (although Im guessing it wont, because thats an entirely different connection protocol via the BES server and Exchange (right!?) )
On the iPhone, (iPhone4, IOS4.3) I've read all the various articles running through every iteration of combination of username and domain but get a failure to connect generic error.
If I use the ActiveSync tester app on the iPhone, I get 'OK' status for everything until it gets to test the user, and I get the 403 error, same thing.
The AS Tester app on the iPhone is saying OK for connection, and its reading the Exchange version, (so it is handshaking with Exchange) so I can use these details to populate the Account settings on the Exchange mailbox wizard on the iPhone, so I feel this is all right.
I am however, missing something,,,.......could someone give me a hand? I've spent three hours reading before posting and taking up someones time, so I'd be grateful.
