BlackBerry Z10/Q10 - contacts stop synching or updating (both ways from device and MS Outlook)

Question

Hi folks,
Hopefully somebody can shed some light on this issue we are starting to see more and more at work.
Are users are connected to the BDS10 server.   When they activate the device they are using the Work Account option.
The issues are everything works excepts Contacts.   When they initially activate the device the contacts may or may not come over to device.   May or may not work accordingly with the updates from outlook and the device.   Then out of nowhere the synching and updating may stop.
I have tried everything i can think of with the user:
moved contacts into a sub-folder
exported contacts to .csv and then re-import to possibly eliminate a bad entry
delete and recreate the workspace
delete and readd on the BDS10 and then delete and recreate the workspace
guided the user to the old BB Article:
http://btsc.webapps.blackberry.com/btsc/viewdocument.do?noCount=true&externalId=KB10009&sliceId=2&cm...
Some databases failed to synchronize: Address book
If the above error occurs, please follow the below checklist
1)  Ensure that at least one of the following fields for the contact is populated(not blank)
     First Name
     Last Name
     Company Name
2)  Check that there are no special characters within the BlackBerry smartphone Address Book, IBM Lotus Notes address book, or Microsoft Outlook contact
Special characters include: () # $ @ ! & % " - , ^ " ; ,
NOTE: these users have 800 or more contacts, one user has 3093 contacts!
NOTE: these users stated they NEVER had this problem with THEIR OLD BB DEVICES!
NOTE: our company is using MS Exchange 2003 ActiveSync in relation to user's mail store.
Any help would be appreciated!

Answer 1

Outlook/BB contact syncing seems broken. I have around 50 contacts and it couldn't sync those properly either. i was getting duplicates each time the device was restarted.
The best way to sync contacts on a Z10/Q10 is to add the contacts directly to your mail box. I added all my contacts to me @live.com address book and my Q10 pulled those contacts just fine.
