Security issue regarding connection information.
Implemented a SharePoint and the users open the spreadsheets through the web, but they have the option to open in Excel too, can you block this option?
Or if it is not possible, when they open the file in Excel, can you block the data visualization of the connection to the bank?
In reading mode, they can not edit, but still have access to the menu. In restricted reading mode they are not even able to access the file.
The only solution would be to implement IRM through AD RMS?
