Using Outlook 2010 and Outlook's contacts, as I've done for years, I can create a new email then select all the addressees from the contacts folder(s).
The only caveat is that the Contacts folder(s) need to be marked as "Show this folder as an e-mail Address book" on the folder's Properties / Outlook Address Book tab.
The linked posts you refer to seem to be discussing Windows Address book which, AIUI, was a separate application. If that's what you're using then sorry, I can't help.
Happily running Windows 10 Pro on both desktop and laptop
We have more and more laws, and less and less enforcement
