Dropbox: Unable to Open Microsoft Files Locally Through Dropbox Desktop App / "This App Has Been Blocked" Error

Environment

U-M Dropbox, Microsoft 365

Issue

When I open a Microsoft file in the Dropbox desktop app, I receive a pop-up that says to sign into a Microsoft 365 app for Dropbox. If I sign in, I receive an error that states, "This app has been blocked for your team." When I try to close out of the pop-up, I receive an error that the file cannot be opened.

Resolution

This issue occurs when someone has previously connected "Dropbox for Teams" as a Place/Connected Service in the locally installed Microsoft 365 desktop apps. The "Dropbox for Teams" connection must be removed to resolve this issue.
