We're trying to share an excel workbook through SharePoint which sends a link through mail with "web=1" which calls for excel web access. since the document has unsupported features in OWA, it prompts us to open in Excel client,, but surprisingly the "open" button is disabled. .
things we tried:
- "Open in Client" feature is enabled at the site collection.
- Office 2013 is installed
- Added the sites to trusted sites list in IE
- verified on multiple browsers IE 11, Google Chrome and Firefox.
- Have full control permissions.
We believe it's a bug,, do you have any clue about it or any workarounds?
