Hi,
In Dynamics 365 Finance and the upper top right you have the "Open in Microsoft Office" button which allows you to Download/Open or save documents (Excel).

When clicking the "Download" button (in my example for the Trial balance but its consistent for other exports) then the Excel file is opened in the Office Web Preview (WOPI) where you then can see "Save a copy to OneDrive" button.

Web preview after clicking the Download button (https://view.officeapps.live.com/) where you can see the Save a copy to OneDrive:

Clicking the "Save a copy to OneDrive" presents a sign in option to a Microsoft Personal account (https://login.live.com/) and not the Work account sign in (which would be expected). My question is there a way to configure or change this behavior so when clicking the "Save a copy to OneDrive" actually uses "for Business" sign-in. Preferably SSO and the user that is signed in the Edge browser which is the default behavior when using other Microsoft applications?
