Read-only error saving to network
 

We have many Excel files saved to a server. All but one of our users can
open the files directly from the server and make changes. They can then save
the file back directly to the server. One user gets a read-only error
message each time he tries to save the file on the server. It prompts him to
make a copy. None of the files are marked as read-only. He has no problem
opening the files, just can't save them. Doesn't seem to matter if he
created the file or someone else did.

Thanks for any help
