External Users
1. External Users will receive an email similar to below when you have shared a SharePoint Document with them
2. They can click on open to get access to the file. Microsoft will then ask that user to confirm their Identity by sending a Code to their email that must insert into the form.
After inserting the Code and clicking Verify the user will be granted access to the document/file.
Internal Users
The process for internal users is very similar - they just won't have to enter any codes as their are members of the SAFELANEGLOBAL organization.
