For all the nice things I say about OneDrive, i'm frustrated with them today. Someone shared a folder with me, and I can no longer make the "Add Shortcut to my Drive" option appear reliably for me. This was the way to accept a folder invitation previously, and it worked reliably as of last month. Now, when I do locate the option, it just adds a web shortcut (.url) to my drive. The previous shortcut was more like a symlink, allowing me to access the files through Explorer. Now I just get a file that opens my browser to the folder. These are obviously not the same thing at all. Maybe this is what happens when someone only gives me read access to the folder? Either way, this is not intuitive and as much as Dropbox sucks in most other ways, they got this part right.
Although whenever I do figure this out, at least the folder won't be taking up space in two people's drives.
