Can anyone please help? I got some problem establishing an activesync connection with HTC Ameo, Tmobile locked. Here's the case:
I use win XP+SP2, Activesync 4.5. Activesync connection has been working a few months ago but now it isn't. I connect the HTC, the system recognizes it, the green arrows go around for a while, then the message: "Activesync cannot connect the windows mobile powered device. To troubleshoot problem, click ok." And the same time HTC says: "This device is not allowed to connect to the desktop computer."
In the device manager i can see 'Windows CE devices/HTC USB sync'
-I clicked ok to troubleshoot, everything was ok but it didn't solve the problem.
-Tried fiddling with 'enable advanced network functionality' - no good whether it's on or off
-Reinstalled Activesync 4.5, also tried 4.2
-Turned off firewall, virus software
T tried to connect today this HTC Ameo to a different PC, 64bit, win7 + windows mobile device center 6.1. Same results. The HTC writes out that it is not allowed to connect to the desktop PC.
