I have Office 365 and this happens only when I close any file in Excel. I do not have this with Word files.

I ran into the issue again this morning when I tried to close a file, in Word, that had been created some time ago. It did not occur when I closed another file that I had looked at last night and that had been created more recently. I am trying to explore the previously suggested idea that this glitch affects files that were created before one of the recent updates. In any case, the workaround, x-ing out the dialogue box, seemed to work just fine. It is only frustrating that Microsoft does not seem to have any sense of urgency with these kinds of frustrations.

Thanks, I hope that they get on this ASAP. It does become rather tedious having to go through on more step when things should be quicker these days.

Just a reminder - in my experience:  When it requests your login, you can simply exit the pop-up (X) and it will go away and the file will be stored as expected (OneDrive).  Check with Windows Explorer for date and time.  This is my experience - 100% of the time.   Therefore, I have not downgraded - I just live with it for now, hoping for a fix in the next release.

Certainly if you want to get rid of this annoying pop-up you could downgrade but that might reverse some security patches.

For me, it appears that if I exit one time, the pop-up does not return until a reboot.

Again: Win 10 Pro, Office 2016 (not 365).

Just a thought..

That's what I've been doing too; least hassle and seems to be risk-free.  Indeed it seems to be related to a login on another machine.  Now waiting until there will be a fix....

I have recently noticed that this dialog box appears to also trigger sometimes when I attempt to open the PowerPoint file menu. But, for some reason, it is a lot more disruptive in PowerPoint, as the window cannot be closed and is completely non responsive. So far, in such situations, I have only been able to exit by terminating PowerPoint via Task Manager. 

Just to clarify, this non responsive version of the dialog has only appeared in PowerPoint so far. I do see the box in Word/Excel but they can always be closed in such situations.
