On our SharePoint 2007 SP1 farm, intermittently, when a userÃÂ opens a Microsoft Office document (usually Excel)ÃÂ for editing by single-clicking its name in IE,ÃÂ the following error dialog mysteriously occurs when Office opens:
File in Use
myfile.xlsm is locked for editing
Open 'Read-Only' or click 'Notify' to open read-only and receive notification
when the document is no longer in use.
The problem is, nobody else is editing this document, and the identified user ('domainname\yourname') is the name of the current user (the person opening the document right now)!
This is not "user error", e.g., the same user editing the file from two different computers, or the file being checked out. This is a real, intermittent problem. If the same user opens the same file again 1 minute later, the problem might be gone, even though nothing changed.
It's almost as if some kind of intermittent race condition is happening, where the document gets locked too early...?
We are completely stumped. Any ideas?
