Can multiple users simultaneously check-out a file from document library in MOSS 2007?If yes then how can we do thatIf no then is there any way to put a document in document library so that multiple users can work on this document at a time.
no. You can not put a document in a state that allows for collaboration efforts to be saved. You do not have to force check out but if you do not, the last one in wins.If you do force check out, then only one person can have the file at once.
