I sync my Droid 2 contacts from my corporate MS Outlook 2007 / Exchange Server account. During the sync process, several contact groups are created in my Android Contacts list which do not exist in my current Outlook Contacts list. One group is created with 360 contacts and another with 148 contacts. These unwanted contact groups are not random but I recognize them as backup and temp groups which I had created within Outlook sometime back. However, I have long since deleted them from my MS Outlook configuration and as I understand it consequently from the Exchange Server. I confirmed with my corporate IT that these phantom groups do not exist anywhere on my local machine nor on the Exchange Server. However, though I have performed a factory reset on my phone and removed / recreated my corporate account on my Droid 2 several times, each time during the sync process those phantom groups and their contacts are somehow pulled from Exchange Server.
The unfortunate result is that I have dozens if not hundreds of duplicate contacts linked and merged together on my phone with some data coming from my current, active Outlook Contacts list and some data coming from the outdated and deleted phantom contact groups which I cannot find in my Outlook or Exchange server.
Though my Droid 2 always syncs these phantom contact groups, I have recently re-synced my entire Outlook data to my local laptop from the Exchange server and each time none of those deleted groups / contacts is synced. Also, if I access my contacts through Outlook Web Access I only see my active, current Outlook Contacts list and none of the phantom groups / contacts. Since Droid/Moto/Android are reconstituting previously deleted Outlook Contacts groups, clearly they still exist in some form on the Exchange Server. Outlook does not find them but Droid/Moto/Android always see them and unfortunately decide to pull them down to my phone.
Elsewhere there is discussion of syncing problems related to Outlook contact categories. But I can rule this out as a factor, since I verified that I have not assigned any categories to any of my Outlook contacts.
Are there any Exchange experts out there or anyone with knowledge or experience who could shed light on this mystery?
