Excel sharing violations when saving to Dropbox

[ECRFF]

I just started having problems saving Excel files to Dropbox yesterday. 

First, I get this message:

Then when I click select, I get this:

Then when I click okay, I get this:

Then it creates a temporary file, which I can’t find, and if I try close the Excel file, I get the same series of messages.  What is going on?

When I access the files through the web instead of on my local drive, I can see the updates so I think it's ok. I made an excel file copy just in case though and that won't save to Dropbox locally or my desktop so I think the issue is with Excel. If I can see the file updates online on Dropbox will they definitely be there if I abandon the Excel copy in order to check the Excel status?

I should also clarify that all the work I did on this spreadsheet was done online on Dropbox as I couldn't open the file any other way. I'm not sure of file size. Where can I view that?

Thanks for the screenshots @Janine45 - much appreciated! 

Have you granted Dropbox full disk access as outlined here?

Hi Walter, no, not yet. But I will do in the morning. Have to finish for today. Thanks

Let us know of any updates when you get the chance @Janine45

Morning Walter, all appears to be working now. I had a colleague check they could view my changes on Dropbox files, then I shut everything down and did a full reboot. Fingers crossed the issue is fixed. Thanks for your help
