Morning all (at least it is here in the UK!),

I'm hoping someone will have come across the following error in the past and
may be able to suggest a course of action to remedy.

It appears on opening the excel document, and is in an "exclamation" message
box, with a "Microsoft Excel" title.

Content reads: "File is locked. In order to save changes to the file, you
can either close the file before making any changes and then re-open it, use
Save As (File Menu) to save the file using another filename, or turn off
Shared Workbooks and then save the file."

Saving the file under another name doesn't work, as the new version also
suffers from this "lock" issue and displays the same message on opening.
The file is not shared, so we can't really turn off Shared Workbooks...

Any suggestions gratefully received!

Thanks
DS
