[Tilt, TyTN II, MDA Vario III Windows Mobile ROM De] Toaplan:
The Problem: I cannot get Exchange to sync correctly when using any 6.1 ROMs.

AT&T Tilt

AT&T SIM

Exchange 2003

Radio: 1.58.26.20

I really need to be able to Exchange sync in order to accomplish my job. From reading though the many 6.1 threads and searching around, I have found that people seem to be occasionally running into this problem, but there hasn't been any resolutions mentioned yet. The problem for me is that synchronization will not occur in ActiveSync. At one point, it would sync my contacts even though it said the sync failed. Others have reported that it will sync contacts and calendar but not email.

The Active Sync error code that I get after flashing a new 6.1 ROM and setting up Exchange the normal way is:

Result: Synchronization could not be completed. Try again later.

Support Code: 0x80830003

Here is a list of things that I have tried so far from searching and asking around that did not work:

1. Didn't work: Installing "remove hidden proxy" .cabs.

2. Didn't work: "What, exactly, are you having issues with? It's not an Exchange 2k3 incompatibility, as mine is synching fine. I did have to go into Settings > Connections > USB and turn off advanced network capabilities, though."

3. Verify the following Exchange setting (already checked): "On the Exchange server, launch Internet Services Manager. Right click on the Microsoft-Server-ActiveSync virtual directory and choose Properties. Select the Directory Security tab. Click the Edit button in the Secure Communications section and select the option to 'Ignore client certificates.'"

4. Verify the following Exchange setting (not running Exchange 2007): "I also had trouble syncing with Exchange. I run Exchange 2007 and had to enable the option to allow the enrolment of non-supported devices in my ActiveSync policy. With WM5.0 or 6.0 it always worked flawlessly."

5: After trying kewlair's suggestion:

"The first issue I had was the initial setup. I set up my account properly, but ActiveSync would report that it cannot sync at this time. I knew that I had to uncheck the Use Proxy for this Connection option to solve this issue, but I couldn't find where to get to that setting for the MEdia Net connection that was being used. I finally found it in Settings -> Connections -> Advanced Tab, then tap the Select Networks button and where it says "Programs that automatically connect..." select MEdia Net instead of My ISP and then you can tap the Edit... button and remove the proxy server selection."

...attempting to force a sync gives this. I also tried changing "Programs that automatically connect..." to My ISP with the same result:

ActiveSync tries to connect using either MEdia Net or My ISP and then says:

"Cannot Connect

Dialed: Cannot connect for an unknown reason. To check your connection settings and change them if needed, tap Settings. If the problem continues, reset your mobile device according to your manufacturer's documentation and try again."

ActiveSync Reports: "Waiting for network"
