Hi all,

We are having an issue with excel files becoming protected out of the blue. We create files using a template from another user. The template contains macros and links to other documents. We are able to work within the file and save to it for a couple of days and then poof, it becomes unusable because the worksheets become protected. We do not know the password because the creator has left the company and we don't have any way of contacting them. Is there a function key or maybe keystrokes which would enable the protection feature? We are at a lost and it's only happening to a few documents. We use the template frequently and most of the documents are working fine. I really would appreciate any help/advice on this issue. Thanks!
