I'm having a similar issue.
So after many years of faithful service, my HTC Touch Mogul started having issues, took it to Sprint, they replaced it with HTC Touch Pro. After 24 hours of major issues, took it back, and they said "bad radio" and gave me a Touch Pro 2
Now to my issue. I use MS Exchange for email, and have the emails pushed to the Touch Pro 2. I am having issues with sound notification when an email arrives. This is what I've discovered:
The first email to arrive after I've opened and closed Outlook doesn't cause a a sound notification. The home page is updated and shows "Outlook E-Mail: 1 Unread"
The second email arrives and I do receive the sound notification, and home page shows "Outlook E-Mail: 2 Unread"
If I open Outlook, then close it, the next email I get doesn't have a sound notification, but the next email after that does create the sound notification.
So basically, after closing Outlook, the first email I receive does not do a sound notification, but home screen updated. The next email I receive creates a sound notification and updates home screen.
I don't use the Touch Flo 3D home page, I use the default WinMo 6.1 touchscreen. I have stock everything.
Any ideas on how to get the sound notification for the 1st email and all the others?
