I'm a SharePoint designer and I work in SharePoint Server 2013. I work in a
test environment, I do not have OWA configured (but it will be on the production environment).
I uploaded a document to a document library for testing purposes (nothing special about it just a default document library with a dummy document), and when I clicked on the document I could choose to either open it in edit mode or open it in view only mode.
I chose the edit mode, the Word document opened in my MS Word client and I added some lines. I then saved the file, and I was amazed by the fact that it saved the file to SharePoint again (I thought I had a local copy).
If I try to reproduce these steps now, it just keeps downloading the document. I no longer get an option to open it, it just automatically downloads a copy of the document. I didn't even change anything in the site, I just refreshed the page and suddenly I can't edit the document no more (I can still download a copy of it, but that's not what I'm looking for).
Now my question: how was I able to open and edit it the first place, and why can't I do this anymore? I changed nothing at all, just refreshed the page and suddenly I can only download the document instead of edit it.
Any help and info is really appreciated, thanks!
