Ok I have had partial success - all the Google, Facebook and Skype contacts in the respective folders are gone. The folders are still there, but empty. The technician I am working with is going to get back with me on a few days on folder removal.
Here then is the process to remove individual contacts:
(1) Open IE Explorer ONLY (not Edge, Chrome, etc) - In search, type iexpore.exe and open 'Internet Explorer Desktop app'
(2) enter outlook.com in browser search to open your online Outlook.com
(3) From the menu grip in upper left, select 'People'
(4) Use Function button F12 to open web tools and select Emulation
(5) On the left side under Mode, find 'User Agent String" and select "Internet Explorer 6" [Document Mode will change to 5 (Default)]
(6) Select 'Contacts' in left side menu and then the contact folder that has the contacts to be deleted
(7) Select the top 'check-box to select all contacts on page, then select 'delete' (see screen shot below
(8) Continue process until all contacts deleted
(9) Folder will be empty, but not removable - more to come in next installment!
(10) You MUST return Mode to "Internet Explorer 11 (default)". Document mode will automatically return to '11 (default)'
The process above assumes that you have already disconnected the accounts from their origins so that they will not automatically repopulate. Somewhere in this thread that process is explained.
Feel free to add or make changes to improve my instructions.
