I have the exact same issue. I imported my contacts through a CSV...it seamed to work fine. Then it started duplicating contacts, and wont allow me to delete them. I have the cosmos as well. I reset my phone so there were no contacts, then tried to delete them from backup assistant. No luck. I called tech support and had a guy log into my account. He was able to duplicate and verify that there is an issue. He created a ticket for their engineers. The ticket number he gave me is: R8333214. He told me that the turnaround time for tickets is around 48 hours. Tomorrow I will call back and get an update.
This is pretty rediculous though. There is no way I am going to manually insert my ~200 contacts.
Backup Assistant won't import my Outlook contacts cvs file. I export to a cvs excel file and have tried the exact file with all the garbage, trimmed it down to just the name and phone number and in a number of formats to include with and without a header title row. I get an error message that says I need the first name, last name, and phone nujber or company name with a list of every row number. Backup assistant is a 'dumb' program without any help for very widely used and obvious apps like Outlook. Can anyone point me to a solution so I can import my contacdts?
