The UA is not serving up a username when connecting to Onedrive (per screenshot info) and therefore is unable to check if the user is in our policy group, causing denial. This is only occuring with Onedrive and no other websites that I’m aware of. The policy blocking Onedrive is by the File Storage/Sharing Category.
For a little more info on our Policy, we have one setup to allow all File Storage/Sharing sites, and when I add a user to this group, all websites work just fine with the exception of Onedrive.
This is occuring on all OS, fresh UA installs, different browers, etc… Any suggestions would be greatly appreciated.
