Today, during the keynotes sessions a quick overview of the new Office tools capabilities has been given.
Looking at One Drive, a lot has happened since the last ESPC. I have picked couple of features that I particularly liked.
The possibility to highlight a file and list any conversations or tasks around the files.
The one drive sync change is now smarter, instead of uploading the entire file, it can check for what has changed and only upload/downlod the fragments that changed.
Working between outlook and onedrive, the recently changed files is a great feature when trying to attach something from one drive.
