Have a customer complaining that on some large files (~1Gb) he is getting a message that the file can’t be opened, it is open elsewhere in “exclusive mode” (translating from French, I have never seen this message box before). This does look like it’s on a network share of some sort (address blanked out below for confidentiality reasons).
I have experienced problems saving files on a network - and there has been some noise of that here as well from various people - but never about opening a file… Normally it should just tell you it’s read-only if it is in use elsewhere - which is not the case in this instance either…
