Some O365 users who recently got migrated from exchange server are unable to open SharePoint site office documents in internet explorer. They are able to open in chrome though.

I have checked reinstalling both IE and O365 , But no luck. I know something is blocking IE office addons to open the file in browser But don't know how to fix it.

here is the very famous error message he gets

"To open this workbook, your computer must have a version of Microsoft Excel installed and your Web browser must support opening files directly from Excel in the browser"
