The real genius is how office365, office, sharepoint, Onedrive and even lync refuse to play nicely.
Click on a document in Sharepoint, opens in office365, click on edit, opens it then says, "this needs to checkout", click checkout, says this can only be done in word, click to download, get a warning that this might damage your computer, click ok, Click to edit again,
Work on doocument
save, don't even think about saving the document to onedrive
It might checkin depending on the phase of the moon and the I-ching.
Check status in sharepoint, it may or may not show it as checked out to you.
Try and send document by lync to somebody else because they can't get the sharepoint "allegedly locked" version.
In the end we have created a wonderful collaboration tool of all sitting in a group around a single laptop reading the document together. We are thinking calling it "reading circle" or "watch with mother"
