I have problem with opening documents in SharePoint. For time to time users reported me that they can't open documents (word, excel but the most often excel), when they try to open they see "Document is locked for editing" or that "Documents is locked for other user" but none is editing documents. This is very annoying, because sometimes we must save copy of documents to be able to work.
How I can fix this?
I will very grateful for help, Andrzej
