I have a client who is a Blackberry Q10 user; her one account setup on the Q10 is her corporate Outlook mailbox, which is in Microsoft Office 365 and the cloud.
It appears that the Q10 will arbitrarily and automatically link contacts in her Outlook contacts; that is to say, two contacts in her Contacts folder will get linked by themselves. This causes her frustration as she will search for one contact and the linked contact gets shown instead, leading her to think the sought for contact is missing.
And just to be clear - this is not linking to contacts in Facebook, or another app; the Q10 is linking contacts to other contacts in her Outlook contacts folder.
Is there any way to disable the contact link tool on the Blackberry, so that linking is not being performed? This seems to be isolated to the Q10; her iPhone does not exhibit this problem.
