We are soon to start managing another organisations ICT environment and for the first time intend to implement Office 365 to support their needs.
They are only a group of 25 users - and Office 365 will see to their Exchange/Outlook requirements. But when it comes to file services they run Microsoft Access and GIS mapping data files - so this is not the normal Word/Excel/PowerPoint (Office) file access requirement I believe a Cloud service can properly support (although they will be running the standard Office apps also).
This implies I would need a local file-server - and anything local means needing local authentication from a local DC. I am trying to simplify this as much as possible so wonder if you can help?
