Pfff, I just sorted out all my contacts. I built up 485 contacts over the years in Exchange. Some of them merged with other contact data on N900 and N9, like photo or address, maybe Skype, LinkedIn, I don't know. But the normal sync with Exchange didn't bring them to the Jolla. Then a sync over bluetooth from the N9, no joy either. In the end I exported all contacts on the N9 into vcf cards, browsed through the Jolla contacts to find out the missing ones. Painful, as I found no way to see a long list of names. The grouping by initial makes you go up again after finishing A to click the B etc. Anyway, I found 137 names missing. Merged the vcf files into one file. Sent it to the Jolla, no joy. In Excel I threw out all the lines I mistrusted, leaving plain and simple vcf cards with 1 phone number and 1 e-mail address. Pasted those into a new file, sent it to the Jolla by bluetooth and it worked! There may be an easier way, but I did it!
