I have a spreadsheet in OneDrive that I have shared with another user (can edit). At first, it shows up in her "Shared With Me" location for about a day. The next day her "Shared With Me" shows up empty.
If I create a link to share, it works fine so she is able to access the file. I have several files I need to share with several different users and they all have the same problem. I really want the "Shared with me" option to work so we aren't having to keep up with multiple links for multiple users.
