I posted this in windows 7 as it was the operating system that the error is occuring on, but this could be for any office network environment operating system.
User A is using Adobe Acrobat to create a PDF saved to the network, User B attempts to open the PDF from a competitors PDF software (bluebeam) and is getting "File in use..." on bluebeam. If user B opens the file in Adobe Acrobat everything is fine but gets this error if opened from bluebeam.
Can someone please explain how the file in use or read only process in general works. This file is obviously not read only, but IS while its in use, but for some reason after exiting acrobat the PDF is still acting as though it is in use.
