Something I find myself wanting to do pretty frequently is storing an email attachment somewhere into SharePoint or OneDrive for Business. I want to simply drag the attachment from Outlook directly into SharePoint or OneDrive in the browser. Alas, I cannot. I am forced to save the attachment somewhere (my Desktop, most likely) then either drag+dropping it into SharePoint/OneDrive or using the upload function in SharePoint/OneDrive to get it uploaded.
It should be easier than that. Microsoft, please consider adding this functionality to get even more user-friendly integration between your suite of products. I’ve submitted a UserVoice suggestion for their consideration. Please vote for it?
