I have O365 business, and I shared an Excel file with an external user (not in our AAD/domain).
They can open the Excel file in their browser with Excel Online, but the "open in desktop app" doesn't show up for them.
Is there a setting I can change to allow this external user to open the file in the full Excel program?

@Shawn Keene To allow "Open in Desktop" functionality, you need to add the person you are collaborating with as a Guest in your Azure Directory. Follow these steps: https://docs.microsoft.com/en-us/azure/active-directory/external-identities/b2b-quickstart-add-guest...
Once your Guest is added, go to the file or folder you would like to share, and enter the Guest email address.
Note: In order for it to work, make sure your org settings allow sharing with guests: https://docs.microsoft.com/en-us/sharepoint/turn-external-sharing-on-or-off
If this worked for you, please give it a thumbs up.
