I have a windows phone on which I have a locked up MS Account. I need to restore the phone but first I need to save all the contacts - how can I export the contacts to another device without having the MS Account active?
The best method is to unlock your MS account by following the method shown in this link
Or just use a contact manager app available on the apps store to backup your contacts. for example i use Rap dialer. It has a backup/restore feature (It uses Onedrive- you could make a new account) you could also try out other apps
You don't need it. When you log in again with the same Microsoft Account all contacts will return
You can use the Transfer my Data app from Microsoft. It can directly transfer contacts from one phone to an another. Or else you can export contacts to SD card and import them in another phone.
