WOPI Version of .xlsm files opening in Desktop App. Why is this happening?

Hey hshupe16, let's jump right into this! 

Does this only happen when the user is trying to open .xlsm files? Do you notice the same behavior with other files too? 

I'd love to know an estimate as to when this started happening. 

You also mentioned that the files are offline. Do you mean they're available offline, or online only, and if so have you tried changing their status to see if you notice any difference? 

Lastly, you mentioned you've reached out to our Support team. Can you share your ticket number reference with me, in order to locate it on our system? 

Keep me posted, and we'll take it from there!

Here is my ticking reference Ticket #24999726

This started happening Friday but with ChatGPT I was able to solve it my turning off the extension to excel for this user as all xlsm files are offline not online-only. Is this a permeant fix I am not sure but now for this user xlsm files open with ease in the desktop app. 

Thanks for the ticket ID hshupe16 -  I was able to locate it in our system and pass your comments on so that we can have all the relevant information under one place.

Apart from that, I'm glad to hear you managed to sort it out in the end and thanks for keeping us in the loop too!

I have one user that I just setup a new PC for that is having this issue. Seems that opening Excel files causes this "https://wopi.dropbox.com/wopi/files...[file name].xlsx" is open in another application error. Never had this with any other user and I'm struggling for a solution at this point. The only way to open files is to force close the dropbox app, open the file, then open the dropbox app again; which is not exactly convenient.

It sounds like this has something to do with co-authoring, which I never explicitly turned on. Would like to know if there is a way to disable this from the admin side so none of my users have this problem.

Hi Jon_DFH, could you clarify exactly how the user is opening the file from the following options:

• Within the Excel app by navigating to the file
• Selecting it from the Recent files page in Excel
• Double clicking the file in the Dropbox folder
• Or, some other method

This info will help us out!

Double clicking on the file through the Dropbox folder. We have our files set to online-only by default. I set ever PC up exactly the same and this is the first time I've ever seen this error.

Could you try marking the file as available offline/local to see if there are any changes when opening the file?

If you believe you enabled co-authoring, have you tried disabling it to see if this helps?

We did try marking as local with the same error message. I have not changed anything on the admin side, so as far as I know co-authoring was never turned on.

I just went ahead and set all the Microsoft apps to "block" though as a precaution. Is there anything local for this user I need to do to disable co-authoring?

There shouldn't be any local options, as co-authoring is disabled from the admin console, which would disable it for the whole team.

Looks like at some point "Dropbox for Teams" was added as a connected service in Office 365. Not sure why. Removing that looks like it solved the issue. Doesn't sound like whatever that service is works properly.
