What does "locked for Shared Use" mean, exactly?

I'm sorry, but I don't think it's reasonable to expect users to clear their entire browser cache just to make Office 365 function semi-normally. The cache exists for valid reasons, and I have valid uses to retain some of the information stored in the cache. I don't want to delete this just to get into a document that I haven't locked.

This worked for me, my "check-out requirement" was already set to "no".  When will this need to clear the cache be fixed?

It is now 2020 and I have the same problem. Nothing helps but wait, wait, wait.... And then it suddenly goes away. Hurray!

I had a similar issue (user has a spreadsheet that they want to do concurrent authoring with another user).  It only allowed the first person to edit the file and locked the workbook.  What I discovered is that while the file was saved with a .XLSX extension, it was actually saved as a Strict Open XML Spreadsheet (*.xlsx).  Saving the file back as Excel workbook (*.xlsx) removed the artificial lock and allowed for concurrent authoring.

Writing as of Aug. 14, 2019. I am experiencing the same issue, which I have experienced countless times in the year that I have used OneDrive. As you note in your post, this issue seems to appear at random (i.e., not prompted by any discernible activity caused by the issue), and it disappears just as randomly. 

Clearing cache and credentials manager does not fix this issue, neither does rebooting, nor signing out of Office 365, or even signing in using InCognito/InPrivate mode. Changing browsers has no effect. Flipping the VPN on/off has no effect. As the user who apparently locked the file, I am certain that indeed this did not happen (i.e., if it got locked, I have no idea how), and that the file is not also being used by another person. It simply fixes itself at some point....

which is entirely unworkable in an enterprise environment. 

I was able to speak to and conduct remote support with a MSFT Tech Support Employee. In fact, one of the greatest pleasures I've ever experienced was watching this person read (ヾﾉ•᷅ ༬•᷄ )'s post line-by-line, which I am copying below for posterity. Spot on. 

As someone else noted, MSFT basically gave up when they saw that the issue was "fixed" - that is, we could not replicate the error. I don't understand this logic at all - if a tumor comes and goes, wouldn't you still want to know how you contracted cancer? 

At the same time, I do understand that O365 is a complicated piece of tech, so this bug could be buried nice and deep like. That said, it's clearly a bug that's affecting productivity of users. I never had this issue with Google Drive, which has its own host of concerns, so I don't think we're asking for too much - I simply want to be able to move files consistently!

Please allow me to paraphrase for Microsoft...since they can't say it.

Dear O365 User,

If you cannot already tell by our responses, we don't care about your feedback, or about your work files. If you cannot access your OneDrive files through the Office 365 account that you or your organization pay for, that's your own fault. Before you ask anything, are you on a Mac? If so, just expect us to blame everything on that.

Please re-read the generic responses we posted back in 2007, and you will find that there are no helpful links or relatable information regarding your "widespread" issue. If you haven't quit after you were reprimanded for not completing work by your deadline because your files were locked by yourself, then we will ask you if this "answered your question" just to drive the point home. Besides, when you complain about OneDrive, you inadvertently become a perpetual marketing vehicle employed at zero cost, so what's wrong with that? Hm, seems not testing our products is a two-fold return on investment. Good luck!
