I have never seen anything like this before. I work for a Uni as IT support, I have a user who is trying to send a PDF attachment outside of the Uni using Office 365. When he uploads the attachment he gets a notice advising that people outside of the Uni won't be able to view or edit this file. I have changed the permissions to allow this.
Now when anyone opens the file, they are directed to our Staff Intranet share point and told they don't have access.
The file in question was created locally on his home PC, using a local install of Expert PDF. There is nothing to even tell how the file knows how to direct to where our share point is.
I have found a work around and it doesn't seem to be effecting any other files so the user is up and running but I would like to know how this has happened in the first place.
Any ideas?
Thanks in advance.
