Not sure what you mean by customer information, I assume contacts?
There is a product called companionlink that is used for syncing android with outlook. It costs $40 and comes with a free trial.
I have heard that it has problems so I haven't tried it. I export my Outlook calendar and import it into Google calendar.
For my contacts, I exported them as vcf files from Outlook, put the files on my D2, then imported them into the D2.
It doesn't sync but I have them.
yes Contract List !
I use gSyncit. Works great.
