A user of mine has a copy of office365 for business prmium with ODFB and sharepoint etc and wishes for his secretaries/assistants to view/edit a selection of his files. This he has done successfully via a link share, however this seems a grave security risk, whether the link can be shared or not etc, he wishes for the users to at least login to gain access.
We have created a number of users within his organisation however each appears to need a licence to be assigned for access, which seems over kill when Onedrive shares a link for free.
These created users obtain a link and logon e.g email@example.com which is good except they still can't view any of the shared files. I'm sure if we purchases a number of sharepoint licences for the users we could setup a team site however the usage from the users is minimal and not worth the £3.80 per month per user.
So there must be a way of sharing your data on one drive for business in a more secure way than sending a link
