Outlook however expects a comma as a separator in a csv-file as that is what the file format stands for comma separated value. If this was set to a comma, you probably wouldn’t have been reading this -) The reason why Windows Live Mail (WLM), and also Outlook Express (OE) and Windows Mail (WM), used a semi-colon as a separator instead of a comma is because that is what is specified in your Region Settings in Windows to be used as the list separator. Separated file can be done easily via Notepad. Turning a semi-colon separated file into a proper comma Go back to Outlook and import the file.So replace the semi-colons for commas and you’re done. The issue is that instead of commas (, ) being used as a separator, you probably see semi-colons ( ) being used instead. I’m not sure whether I should call this a bug or a feature but luckily the solution is quite easy.įor a change, let’s start with the solution and then I’ll explain my dilemma of whether to call this a bug or a feature. How can I import my contacts into Outlook? The file is in csv-format but when I try to import it into Outlook, I'm being prompted to Map Custom Fields but everything is just on a single line. I’ve exported my contacts from Windows Live Mail on my old computer and now I want to import them into Outlook on my new computer.
