I posted about this in the ApeX 1.0 release thread (
[ROM] ApeX for Droid X - An AOSP Experience)
Basically, you need:
- BlurCalendar.apk
- BlurEmail.apk
- BlurEmailEngine.apk
- Messaging.apk
- UniversalInbox.apk
This will give you the full Corporate Sync capability (Email, Calendar, Notifications, etc)
As stated in the other thread, I prefer the rendering of the emails in the Blur version. They seems closer to the Exchange/Outlook originals.
If you're using ApeX, just copy the apks to your /sdcard/ and then, in "adb shell", get root (su) and type "install <file>.apk" for each one (replacing <file> with the file name!)
