Thanks for answering Tarka Dal. I did try & 'Export' all my email contacts in 'File Explorer prior to your suggestion, but couldn't find a destination named 'People'. I tried again with your comments, but didn't get very far again.
I selected 'Contacts', then 'Export', a box opens titled 'Export Windows Contacts' with 2 different formats to select from: CSV or VCards .vcf. I didn't know which one to select so I chose the VCards .vcf. Clicked on 'Export' & a dialog box opens titled 'Browse for folder' with the request to 'Select the folder for VCF export'. I presume I should select 'Contacts'. Is that correct? Anyway I did, & a dialog box opens: 'Your contacts have been exported in the new format you chose to the location you selected'. But I hadn't up to that point selected any location. What am I doing wrong?
There is no 'People' in the 'Browse for folder' box & even if I had made a new folder titled 'People' & chose that would that have worked?
I also couldn't see any 'Manage' in 'People'. I'd appreciate all further help. Thanks.
