Am I able to create a folder that has a preconfigured set of links that new users would need to access with their own accounts? In which when they go to these new links it would then let them update there Lastpass with their own credentials for each link.
You could use Shared Folders to share sites with LastPass users that they would need access to, although there isn't currently a way to set up a folder or process to "prompt" a LastPass user to add or set up a site account/password in their Vault.
If you have any other questions or would like additional assistance with Shared Folders or how to manage users, you can always reach out to the Business support team for help right away. You can access the support phone number through your LastPass Admin Console > Support or if you can't access the admin console you can request a callback by scrolling down and clicking "Contact Support" on this page and entering your business account info and you should then be given the option to receive a callback usually within less than 5 minutes: https://support.logmeininc.com/lastpass/help/how-do-i-contact-customer-support-for-lastpass-lp010121
I understand I can use the shared folder method. If I do that and put links in there, can each user then have that link use their unique login credentials, or can the link only have one set of credentials?
Shared folders allow you to share only 1 site credential (username/password) with others, so this would not work as you would be sharing one username and password with multiple other users. If you're looking to "assign" items to users, you would need to create a separate entry in LastPass for each username and password combo, then share those items (or change the Shared Folders access settings) to the specific user(s) that should have access to that specific username/password.
Yes, for more information on Shared folder access permissions please see this support article.
