Duplicate contacts in Blackberry smartphone Using Blackberry Enterprise/Professional

For those of you supporting Blackberry Enterprise/Professional Servers, chances are you might come across a device that has duplicate contacts. These can be a pain to resolve especially if the only way you know to resolve it is to wipe the device and re-activate it. Or worse yet, manually delete the duplicates, only for them to come back when the device gets synch'd.

Note, I am assuming that your email account does NOT have duplicate contacts. If this is the case, then you will have to export all your contacts to PST (with the option of not exporting duplicates). Then delete your contacts from your Outlook and re-import from the PST just created.


If the duplicate contacts are only in your blackberry, then do the following.

1. Go into Contacts and then press the menu to get into Options
2. type rset (you will not see it being typed since there is no place to type it. Ensure you have got multitap enabled and not suretype as this makes it easier to know what is being typed)
3. You will get a prompt asking you to confirm that you want to wipe the contacts and repopulate from the Blackberry server. Confirm this.
4. All your contacts will be deleted (time to panic ... not :) )
5. Contacts will then slowly start downloading off the Blackberry server and will appear back in your device's contact list.

Hope this helps those in need.
