Saving files to SharePoint Online is HARD
It's been a while since I made this post and I'd only think it fair to follow up with it as Microsoft has delivered some real positive improvements in this space.
Files on Demand - https://docs.microsoft.com/en-us/onedrive/use-group-policy#FilesOnDemandEnabled
AutoMount Team Sites - https://docs.microsoft.com/en-us/onedrive/use-group-policy#AutoMountTeamSites
Save to SharePoint site - https://www.microsoft.com/en-us/microsoft-365/blog/2015/11/09/attachments-in-outlook-2016-ready-for-collaboration/ and much easier when using the two features mentioned above.
Bonus points: Live document collaberation - https://support.office.com/en-us/article/document-collaboration-and-co-authoring-ee1509b4-1f6e-401e-b04a-782d26f564a4
Big thanks to ssquires , LincolnDeMaris , cfiessinger , and anybody else involved with these changes. They were a game changer when they launched and they've been much appreciated by consultants and end-users alike!!
The other way that is open is using the OneDrive for business sync client.
Still requires config to sync libraries people use frequently, but for bulk upload you just save to the local location. It at least cuts out the go find and navigate to the Sharepoint library part.
