When trying to apply a certificate and save a pdf on a network drive, I'm presented with:
]
The document could not be saved. The disk you were saving to or the disk used for temporary files is full. Free some space on this disk and try again, or save to a different disk.

I am using Acrobat Pro, I saw on some forums the solution was to disable "Enable protected mode on startup" but this seems to be an Acrobat reader option.

I have full access to the network drive, there is plenty of space both locally and on the remote location. I can even copy the file to my local drive, attach certificate, and then transfer/overwrite the file back on the network , but this seems inneficient.
