Am using GO Contact Sync Mod quite successfully in general. I prefer to keep my contacts in Outlook on the desktop and have to use an Android phone. Mostly it works pretty well... however...
I now have a LOT of contacts. In Outlook, I sort these neatly into folders. Unfortunately, GMail contacts (and Android phones) do not have the "folder" concept. Instead they have the "label"/"group" concept. In the cloud it is a "label" on your phone it is a "group".
Currently, GO Contact Sync Mod does not provide an option like "Set folder name in Outlook to be contact's label in Gmail contacts." So... that would be my first request. When syncing to Google, add a label (if it does not exist) for the Outlook folder name and set that for the Gmail contact.
Note: For an existing contact, preferrably do NOT clear the other labels. This is a current frustrating behavior of GO Contact Sync Mod: When I go into the GMail contacts tool and carefully manually set labels for all of the contacts, the next time I sync from GO Contact Sync Mod the labels get cleared.
(In my case, I often want to set more than one label for a contact. If I am going to an IEEE meeting, I want to select the "IEEE" group on my phone. If I am visiting "ABC, Inc." I want to set that label on my phone. Some people will belong to both labels.)
Thanks!
