I have a user that has a strange problem.
Every time he opens a particular Excel document, and it is in use by another user, Excel shows the e-mail header, as if he had pressed Files/Send to.../Mail reciepient.
But if the same document is not in use by someone else when it is opened, the mail header doesn't show up.
So it shows every time the document is opened as write protected.
He tried opening other Excel documents as write protected, and all of them show up normally - without the mail header.
Does anyone know what could be the problem??
