1. We are trying to access the underlying email address for an ActiveSync enabled email account.
2. We have setup an emulator to sync with Exchange 2003 ActiveSync.
3. We can send and receive emails in this account and sync sucessfully
4. In accessing AccountProperty.SenderEmailAddress and EmailAccount.Name we are getting “ActiveSync”.
5. Other accounts such as a gmail account are returning the correct item we are looking for (e.g., user@gmail.com).

Could you give us any insight into how we could access this information?

The way the sender information is stored is different on different account types. The supported way to query actual email account settings is via the configuration API - InTheHand.WindowsMobile.Configuration.ConfigurationManager. The provider to use is the EMAIL2 provider. We don't currently have a managed wrapper around that provider so you'll have to build the XML document yourself. The provider is documented here:-
